Answer:
To convert 675000 to scientific notation, we need to express it in the form a × 10^n, where a is a number between 1 and 10 (but not 10 itself), and n is an integer.
Starting with 675000, we can divide by 10 repeatedly until we get a number between 1 and 10.
675000 ÷ 10 = 67500 (one division by 10)
67500 ÷ 10 = 6750 (two divisions by 10)
6750 ÷ 10 = 675 (three divisions by 10)
Now we have a number between 1 and 10 (namely, 6.75), and we know that we divided by 10 three times, so the exponent is -3.
Therefore, we can express 675000 in scientific notation as:
6.75 × 10^5
(Note that we could also express it as 6.75 × 10^2 × 10^3, but this is not in standard scientific notation, which requires the coefficient to be between 1 and 10.)
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

Yes, shining light on metal can cause it to get warm, regardless of the type of light used. When light strikes surface, some of its energy is absorbed by material, which causes atoms to vibrate, leading to increase in material's temperature and this effect is known as thermal radiation.
Does it matter what type of light shines on the meta?The amount of heat generated depends on several factors, including the intensity of light, duration of exposure, and material's properties, such as its reflectivity, emissivity and specific heat capacity.
I case of the metal used to make satellites, it absorbs infrared light, which means that it will be heated up if exposed to this type of light. However, metal transmits X-ray light and reflects visible light, so it will not be heated by these types of light.
Therefore, it is essential to consider type of light used when assessing heat generated by material. Different materials have different spectral responses to light, which means that they will absorb, reflect or transmit different types of light, and as a result, they will behave differently when exposed to light.

18. If we increase the temperature of the tank to 85° C, what will the new pressure be inside the tank?
The new pressure inside the tank would be approximately 101.8 kPa.
What is the relationship between temperature and pressure of a gas?
According to the ideal gas law, PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is temperature in Kelvin.Since the volume of the tank is constant, we can use the simplified form of the ideal gas law: P1/T1 = P2/T2, where P1 is the initial pressure, T1 is the initial temperature, P2 is the final pressure, and T2 is the final temperature.Converting 85° C to Kelvin (85 + 273.15 = 358.15 K), we can solve for P2: P2 = P1(T2/T1) = 101.3 kPa (358.15 K / 298.15 K) = 101.8 kPa.Increasing the temperature of the tank to 85° C would result in a new pressure inside the tank of approximately 101.8 kPa.

Pls needed answer asap thnku smmm
Yes, a research in 2012 called the ENCODE project showed that about 75% of noncoding DNA or Junk DNA do get transcribed.
What is Junk DNA?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.

Esters, amines, and amides have many uses in medicine. Investigate one of the following drugs further: aspirin, Benadryl, or Tylenol and give its scientific name. What kind of functional groups does it contain?
Esters, amines, and amides have many uses in medicine, and so do carboxylic acids, such as aspirin. Aspirin is the drug that will be investigated further. Its scientific name is acetylsalicylic acid.
What kind of functional groups does Aspirin contain?Acetylsalicylic acid contains two functional groups: a carboxylic acid group (-COOH) and an ester group (-COO-CH₃). The carboxylic acid group is responsible for the acidic properties of aspirin and allows it to form salts with bases. The ester group is formed from the reaction between the carboxylic acid group of salicylic acid and acetic anhydride. This esterification reaction makes aspirin more soluble in organic solvents and less irritating to the stomach than salicylic acid.
Aspirin is a widely used medication that has anti-inflammatory, analgesic, and antipyretic properties. It works by inhibiting the production of prostaglandins, which are responsible for pain, inflammation, and fever. Aspirin is commonly used to treat headaches, fever, arthritis, and other inflammatory conditions. It is also used as a blood thinner to prevent heart attacks and strokes.

How many milliliters of 9.89 M nitric acid solution should be used to prepare 3.50 L of 0.200 m HNO3? _____mL
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.

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.
What is radioactive decay?
Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting ionizing radiation, such as alpha particles, beta particles, and gamma rays. This process can result in a change in the number of protons and/or neutrons in the nucleus, leading to the transformation of one element into another. The rate of decay is typically characterized by a half-life, which is the time required for half of the atoms in a sample to decay.

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

How is dry ice defined as solid carbon dioxide?Because the gas when it solidifies resembles ice, ice ice is actually just carbon dioxide that has been solidified. Unlike regular ice, it instantly transforms into CO2 gas instead of melting into a liquid.
Why is dry ice a good illustration of sublimation?Solid carbon dioxide is sometimes referred to as "dry ice." That's because when something warms up and changes state, it doesn't just dissolve into a liquid. Instead, it skips the liquid step and transforms right into a gas.
