What is the mole ratio of C3H6O₂ to CO₂? Write it as a fraction.

Yes, a research in 2012 called the ENCODE project showed that about 75% of noncoding DNA or Junk DNA do get transcribed.

The term "Junk DNA" is often used to refer to regions of the DNA that do not appear to code for functional genes, and their function or lack thereof is still a subject of active research and debate in the scientific community.

While it was once believed that these non-coding regions of DNA were "junk" and had no functional role, recent research has shown that some of these regions may have important regulatory functions, such as controlling gene expression or modulating chromosome structure.

In 2012, the ENCODE project determined that around three-quarters of the noncoding DNA in the human genome did undertake transcription and that almost half of the genome was accessible to proteins involved in genetic control such as transcription factors.

Some scientists, however, have questioned these findings, claiming that the accessibility of these genomic sequences to transcription factors does not necessarily imply that they have any biochemical significance or that transcription of the segments is favorable in terms of evolution.

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 : -

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.

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.

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

Answer: Solubility increases so more solute dissolves

Explanation:

The solubility is a measure of the concentration of the dissolved gas particles in the liquid and is a function of the gas pressure. As you increase the pressure of a gas, the collision frequency increases and thus the solubility goes up, as you decrease the pressure, the solubility goes down.

Answer:

Absolute zero is the theoretical temperature at which all matter would have zero thermal energy and all molecular motion would stop. This temperature is equal to -273.15 degrees Celsius or -459.67 degrees Fahrenheit. It is the lowest possible temperature in the universe and cannot be reached in practice, as it is impossible to completely eliminate all thermal energy from matter.

(1) The larger ion is Cr³+

(2) The larger ion is Ca.

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.

Lithium's electron configuration is 1s^2 and 2s^1 , therefore the orbital diagram would have 2 in 1s box and 1 in 2s box. Thus, option A is correct.

An atom in the neutral state has the same number of protons and electrons. Since protons carry the positive charge and electrons carry negative charge of equal magnitude as that of protons, so, in neutral state the overall charge on the atom is zero.

Atomic number of Lithium is 3. Under neutral state it has 3 protons and 3 electrons. So, its overall electric charge is 0.

If an atom of Lithium loses one of its outermost electron, it is left with 2 electrons and 3 protons. Since, number of protons is 1 more than the number of electrons, the electrical charge on Lithium atom would be positive and the magnitude of charge will be equal to the number of electrons lost, which is 1 in this case.

Solubility.

Explanation:

Solubility is the maximum concentration of a solute that can dissolve in a solvent at a given temperature. At the maximum concentration of solute, the solution is said to be saturated. The units of solubility can be provided in mol/L or g/L.

The equilibrium concentrations of CO₂, H₂, and CO are 0.170 M, 0.084 M, and 0.016 M, respectively.

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

Answer: Therefore, 70.7 mL of 9.89 M nitric acid solution should be used to prepare 3.50 L of 0.200 M HNO3.

Explanation:

To prepare 3.50 L of 0.200 M HNO3, we need to calculate the amount of HNO3 required and then determine the volume of 9.89 M nitric acid solution needed to prepare this amount of HNO3.

The amount of HNO3 required can be calculated using the formula:

amount of HNO3 (in moles) = volume of solution (in liters) x concentration of HNO3 (in moles per liter)

Substituting the given values:

amount of HNO3 = 3.50 L x 0.200 mol/L = 0.700 mol

Now, we can use the amount of HNO3 and the concentration of the nitric acid solution to calculate the volume of the nitric acid solution needed:

volume of nitric acid solution = amount of HNO3 (in moles) / concentration of nitric acid solution (in moles per liter)

Substituting the given values:

volume of nitric acid solution = 0.700 mol / 9.89 mol/L = 0.0707 L

Finally, we can convert the volume to milliliters:

volume of nitric acid solution = 0.0707 L x 1000 mL/L = 70.7 mL

Therefore, 70.7 mL of 9.89 M nitric acid solution should be used to prepare 3.50 L of 0.200 M HNO3.

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.

The volume of the gas will be 560 mL when the pressure is reduced to 125.0 kPa, assuming the temperature remains constant.

Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.

Boyle's law is expressed as;

P₁V₁ = P₂V₂

Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.

Substituting the given values, we get:

P₁ = 350.0 kPa (initial pressure)

V₁ = 200 mL (initial volume)

P₂ = 125.0 kPa (final pressure)

V₂ = ?

Solving for V₂, we get:

V₂ = ( P₁ × V₁ ) / P₂

V₂ = (350.0 kPa × 200 mL) / 125.0 kPa

V₂ = 560 mL

Therefore, the final volume of the gas is  560 mL.
