5. What measures how stressful exercise is on your body?
O A. Frequency
O B. Duration
O C. Volume
D. Intensity
Answer: D. Intensity
Explanation: Intensity is correct, because if you originally were working on a treadmill with a speed of 8, that is how much intensity your putting your body on. And if you put the speed for a treadmill at 11 to increase your exercise, you are increasing the speed you have to run, making it more intense. The more intense you make your workout or training, the more stressful exercise you are doing.

A mixture of 0.2000 mol of CO2, 0.1000 mol of H2 and 0.1600 mol of H2O is placed in a 2.000 L vessel. The following equilibrium is established: CO2(g) + H2(g) ⇌ CO(g) + H2O(g) At equilibrium [H2O] = 0.0856 M. a. Calculate the equilibrium concentrations of CO2, H2 and CO. b. Calculate Kc for the reaction
The equilibrium concentrations of CO₂, H₂, and CO are 0.170 M, 0.084 M, and 0.016 M, respectively.
The equilibrium amounts, what are they?Making an equilibrium concentration calculation. A chemical reaction is said to be in a state of chemical equilibrium when both the reactants and the products are in a concentration that does not vary over time any longer.
The reaction's equilibrium constant formula is as follows:
Kc = ([CO][H₂O])/([CO₂][H₂])
We obtain the following by plugging in the equilibrium amounts from the ICE table:
Kc = ((x)(0.0856))/((0.20 - x)(0.10 - x))
b. In order to determine Kc, we must first determine x using the equilibrium formula and the specified equilibrium H₂O concentration:
Kc = ((x)(0.0856))/((0.20 - x)(0.10 - x)
Kc = (x(0.0856))/(0.02 - 0.3x + x - 0.01x)
Kc = (x(0.0856))/(0.02 - 0.21x)
Kc(0.02 - 0.21x) = 0.0856x
0.02Kc - 0.21Kcx = 0.0856x
0.21Kcx + 0.0856x = 0.02Kc
x(0.21Kc + 0.0856) = 0.02Kc
x = (0.02Kc)/(0.21Kc + 0.0856)
x = (0.02Kc)/(0.21Kc + 0.0856
After solving for the equilibrium concentrations of CO₂, H₂, and CO and substituting this equation for x back into the ICE table, we arrive at:
[CO₂] = 0.170 M
[H₂] = 0.084 M
[CO] = 0.016 M

An isotope of hydrogen, known as Tritium (hydrogen-3), has a half-life of 12 years. If a sample of tritium was prepared 60 years ago, what was its original mass if its current mass is 0.42 micrograms?
Options for answers:
a.) 1.7mg b.) 13.4mg c.) 6.7mg d.) 26.8mg e.) 3.4mg
The original mass of Tritium (hydrogen-3) was 13.4mg if its current mass is 0.42 micrograms.
The formula for radioactive decay is given by:
N = N0 x (1/2)^(t/T)
where,
N = final number of radioactive atoms
N0 = initial number of radioactive atoms
t = time elapsed
T = half-life of the radioactive substance
Let's substitute the given values into the formula:
0.42 μg = N0 x (1/2)^(60/12)
0.42 μg = N0 x (1/2)^5
0.42 μg = N0 x 1/32
N0 = 0.42 μg x 32
N0 = 13.44 μg
Therefore, the original mass of the tritium sample was 13.44 micrograms.

(2) The larger ion is Ca.
What is the size of the ions?In the first pair, we are comparing the cations Cr²⁺ and Cr³⁺. Cations are positively charged ions that form when an atom loses one or more electrons. The charge on a cation tells you how many electrons it has lost. In this case, Cr²⁺ has lost 2 electrons, while Cr³⁺ has lost 3 electrons.
When comparing the sizes of ions, we need to consider the ionic radius. The ionic radius is the distance between the nucleus of an ion and its outermost electron shell.
As we move from left to right across the periodic table, the number of protons in the nucleus increases, which pulls the electrons closer to the nucleus and makes the atoms smaller. As we move down a column in the periodic table, the number of electron shells increases, which makes the atoms larger.

What is the mole ratio of C3H6O₂ to CO₂? Write it as a fraction.
The mole ratio of C3H6O₂ to CO₂ ia 1:y.
Mole ratio explained.
To determine the mole ratio of C3H6O2 to CO2, we need to look at the balanced chemical equation that relates these two substances in a chemical reaction. Let's assume the balanced chemical equation is:
C3H6O2 + xO2 → yCO2 + zH2O
where x, y, and z are coefficients that balance the equation. The mole ratio of C3H6O2 to CO2 is simply the ratio of the coefficients in front of each substance in the balanced equation. From the equation above, we can see that the coefficient in front of C3H6O2 is 1 and the coefficient in front of CO2 is y. Therefore, the mole ratio of C3H6O2 to CO2 is:
1 : y
where y is the coefficient in front of CO2 in the balanced equation.
Since we don't know the exact balanced chemical equation, we cannot determine the value of y and therefore cannot simplify the ratio any further. So the mole ratio of C3H6O2 to CO2 is 1 : y, where y is an unknown integer.

A sample of gas is in a container with a movable piston. The volume in the container is originally 850 ML at a temperature of 467K and a pressure of 11 point 4K PA. What will the new temperature if the volume is expanded to 1125 in El with a new pressure of 99.7 K PA?
If the volume is increased to 1125 in El with a new pressure of 99.7 K PA, the new temperature will be around 808 K.
What transpires to the gas volume in a moveable piston cylinder?Once the piston's pressure has doubled, it goes downward until the gas's pressure and the piston pressure are equal. The gas has now lost half of its original volume. The volume of gas falls to one-fourth of its initial volume if the pressure on the piston is once more increased by a factor of two.
This issue can be resolved using the coupled gas law:
(P1V1) / T1 = (P2V2) / T2
Using the following conversions, we can first change the starting volume to litres and the original pressure to atmospheres (atm):
1 mL = 0.001 L
1 kPa = 0.00987 atm
V1 = 850 mL = 0.85 L
P1 = 11.4 kPa = 0.1126 atm
T1 = 467 K
The new volume and pressure can also be converted to litres and atmospheres:
V2 = 1125 mL = 1.125 L
P2 = 99.7 kPa = 0.984 atm
Now we can plug in the values and solve for T2:
(P1V1) / T1 = (P2V2) / T2
(0.1126 atm * 0.85 L) / 467 K = (0.984 atm * 1.125 L) / T2
T2 = (0.984 atm * 1.125 L * 467 K) / (0.1126 atm * 0.85 L)
T2 = 808 K

Which statement about fossil fuels is true?
Responses
They are an alternative energy source.
They are replaced in only a few years.
They are in high demand.
Answer:
They are in high demand.
Why is fossil fuel bad?
FOSSIL FUELS, USES, NEGATIVE IMPACTS AND SOLUTIONS;
In order to understand why it is bad to use Fossil Fuels, it is first necessary to understand what they are composed of. There are two main types of Fossil Fuels, namely, Coal and Oil.
The Formation of Coal : -
The multistage process that produces coal.
Many millennia ago, tree trunks fell and were quickly covered in water and mud. The bacteria, respiring anaerobically, due to the lack of Oxygen, produced peat. As is illustrated in stage 3, sediments built up over this peat layer and with time, heat and pressure, certain chemical changes turned the peat into Coal, as shown in stage 4. During the compression process, Sulphur compounds leached into the peat layer and eventually became a components of the final Coal. In other cases, Low sulfur coals derive their sulfur mainly from the sulfur components in the coal-forming plants. High-sulfur Coals, however, are now known to derive most of their sulfur from reduction of Sulphate ions to H2S in sea or brackish water in the coal beds by microbial processes.>
The Formation of Oil : -
The multistage process that produces oil.
Oil is essentially the remains of small fossilised sea creatures, that has been compressed and undergone pressures, eventually converted to oil. Oil is commonly accompanied by Natural Gas, which also builds up as a result of the extreme pressures. Sulphur is also found to make a percent of the oil.
The Usage and Combustion of Fossil Fuels : -
Coal and Oil are combusted to convert the chemical energy held to thermal energy, which in turn warms up water so that steam evolves. This team is drafted down a tunnel to turn a turbine, which drives a generator. This is how a power station works.
Upon observing the figure above, if you follow the path of the process, we see that coal enters at number 14 and enters the combuster at number 15. Here, it burns to heat the water at number 19, which is channeled down to drive the generator at number 5, via a series of tubes which converge into one, at number 10.
Coal or Oil or both can be used for this purpose. However the combustion of Coal and Oil releases Sulphur gas, which is dangerous for the Environment, as well as Carbon Dioxide and Carbon Monoxide, as the combustion happens in internal conditions, hence combustion may not occur fully, or in depleted Oxygen.
Negative Impacts of Sulphur Gas, Carbon Monoxide and Carbon Dioxide on the Atmosphere and the Environment : -
Sulphur Gas can dissolve in rainwater to produce a weak, aqueous Sulphuric Acid, which can fall in the form of rain. This can increase the pH of the soil or other water bodies, which can disturb marine ecosystems and even terrarial ones. It can fall on leafs and ‘wound’ them, i.e, destroy tissue due to its corrosive nature, making the plant life vulnerable to pathogens.Carbon Monoxide is a toxic gas that can cause suffocation and death. Although it is a natural component of the Atmosphere, in recent years, due to high industrial activity, its percent composition has increased significantly, which is a cause of concern towards the health of bird life. While it does not cause Greenhouse Effect directly, in the upper reaches of the Atmosphere it can combine with Oxygen to give Carbon Dioxide.…Which brings us to Carbon Dioxide. This is a greenhouse gas. On Earth, all organisms respire to produce Carbon Dioxide, so in the geological history of Earth, there has been equilibrium maintained between Oxygen and Carbon Dioxide in the Atmosphere. This, however, has been disturbed by Man’s industrial activities. This has been due to the high deforestation and lack of replacement of cut-down trees, around the planet. This disequilibrium is best depicted by the graph below.
Prevention and Reduction of These Effects : -
There are numerous methods by which these gases and their effects can be subdued. One notable example for the case of Sulphur Gas, is the “Flue Desulphurisation Method”, which effectively removes the Sulphur and separates it out, hence making it available for use in other Industrial Processes, but in safer compounds, etc.
Replanting of cut down trees can contribute towards of the re-achievement of the equilibrium that has been present in the Atmosphere before Industrial activities led to disequilibrium. Re-planting is a very simple process, but one that can go a long way. In effect, it is a two in one solution, as if we remove Carbon Monoxide emissions by reacting the gas with excess Oxygen, we get Carbon Dioxide. However, the equilibrium in the Biosphere means that is no longer a problem. Thus, replanting of trees is very important.

State the molecular, molar, and mass relationships indicated by equation
Answer:
The balanced equation:
2H2S + 3O2 → 2SO2 + 2H2O
indicates the following relationships:
Molecular relationship: For every 2 molecules of hydrogen sulfide (H2S) that react, 3 molecules of oxygen (O2) are consumed, producing 2 molecules of sulfur dioxide (SO2) and 2 molecules of water (H2O).
Molar relationship: For every 2 moles of H2S that react, 3 moles of O2 are consumed, producing 2 moles of SO2 and 2 moles of H2O.
Mass relationship: The ratio of masses of the reactants and products in the balanced equation can be used to calculate the mass relationship. The equation indicates that 2 moles of H2S react with 3 moles of O2, producing 2 moles of SO2 and 2 moles of H2O. Therefore, the mass of H2S consumed is proportional to the mass of O2 consumed, and the masses of SO2 and H2O produced are proportional to each other.
18. If we increase the temperature of the tank to 85° C, what will the new pressure be inside the tank?

Consider the neutralization reaction:
2 HNO3(aq) + Ba(OH)₂ (aq) → 2H₂O(1) + Ba(NO3)₂(aq)
A 0.120 L sample of an unknown HNO3 solution required 37.9 mL of 0.250 M Ba(OH), for complete neutralization. What is
the concentration of the HNO3 solution?
Explanation:
First, we need to write a balanced chemical equation for the neutralization reaction:
2 HNO3(aq) + Ba(OH)2(aq) → 2 H2O(l) + Ba(NO3)2(aq)
From the balanced equation, we can see that the stoichiometric ratio of HNO3 to Ba(OH)2 is 2:1. This means that 2 moles of HNO3 react with 1 mole of Ba(OH)2.
Using the given information, we can calculate the number of moles of Ba(OH)2 that reacted:
moles of Ba(OH)2 = Molarity x Volume (in L)
moles of Ba(OH)2 = 0.250 M x (37.9/1000) L
moles of Ba(OH)2 = 0.009475 mol
Since the stoichiometric ratio of HNO3 to Ba(OH)2 is 2:1, the number of moles of HNO3 that reacted is twice the number of moles of Ba(OH)2:
moles of HNO3 = 2 x moles of Ba(OH)2
moles of HNO3 = 2 x 0.009475 mol
moles of HNO3 = 0.01895 mol
Finally, we can calculate the concentration of the HNO3 solution:
concentration of HNO3 = moles of HNO3 / volume of HNO3 solution (in L)
concentration of HNO3 = 0.01895 mol / 0.120 L
concentration of HNO3 = 0.158 mol/L
Therefore, the concentration of the HNO3 solution is 0.158 mol/L.
