Finally, Ke = 1358. Therefore, none of the provided options (A, B, C, or D) is the correct answer. The equilibrium constant Ke under these conditions is approximately 1358 in pressure.
The force that a substance applies to its surroundings as a function of area is known as pressure. It is a fundamental physical characteristic that is important to many branches of science, including as physics, chemistry, and engineering. The interaction of molecules or particles with a container's or surface's walls results in pressure. Units like pascals (Pa), atmospheres (atm), millimetres of mercury (mmHg), or pounds per square inch (psi) are frequently used to measure it. The behaviour and characteristics of gases, liquids, and solids are influenced by pressure, which also has an impact on processes including fluid flow, gas compression, chemical reactions, and atmospheric conditions. In many real-world scenarios, from industrial operations to medical equipment, understanding and managing pressure is crucial.
To calculate the equilibrium constant (Ke) for the given reaction:
2SO2(g) + O2(g) ⇌ 2SO3(g)
First, we need to find the equilibrium concentrations of each species by dividing the moles by the volume of the vessel (10 L):
[SO2] = [tex](7.60 x 10^(-2) moles) / 10 L = 7.60 * 10^(-3) M[/tex]
[O2] = [tex](8.60 * 10^2 moles) / 10 L = 8.60 * 10^1 M[/tex]
[SO3] = [tex](8.20 * 10^2 moles) / 10 L = 8.20 * 10^1 M[/tex]
Now, we can plug these concentrations into the equilibrium constant expression for the given reaction:
Ke =[tex][SO3]^2 / ([SO2]^2 * [O2])[/tex]
Note that the coefficients in the balanced equation become the powers in the equilibrium constant expression.
Ke = [tex](8.20 * 10^1)^2 / ((7.60 * 10^(-3))^2 * (8.60 * 10^1))[/tex]
Next, calculate the values:
Ke = (6724) / (5.76 x[tex]10^(-3)[/tex] 10^(-5) * 86)
Ke = 6724 / (4.95 x [tex]10^(-3)[/tex])
Finally, Ke ≈ 1358. Therefore, none of the provided options (A, B, C, or D) is the correct answer. The equilibrium constant Ke under these conditions is approximately 1358.

When 30.0 g of carbon is heated with silicon dioxide, 28.2 g of carbon monoxide is produced. What is the percent yield of carbon monoxide for this reaction? SiO₂(s) + 3C(s) SiC(s) + 2CO(g)
Answer: 60.5%
Explanation:
When 30.0 g of carbon is heated with silicon dioxide, 28.2 g of carbon monoxide is produced. 60.5% is the percent yield of carbon monoxide for this reaction.
The % ratio of the theoretical yield to the actual yield is known as the percent yield. It is calculated as the theoretical yield times by 100% divided by the experimental yield. The percent yield equals 100% if the theoretical and actual yields are equal.
SiO₂(s) + 3C(s)→ SiC(s) + 2CO(g)
moles of carbon =30.0 / 12=2.5moles
3 moles of carbon give 1 moles of SiC
1 mole of carbon will give 1/3 moles of SiC
2.5 mole of carbon will give (1/3)×2.5 =0.83 moles of SiC
mass of SiC = 0.83× 40.09=33.27
percent yield = (actual yield/theoretical yield) x 100%

The final pressure of the nitrogen gas with the increase in volume is 2.91 atm.
What is Boyle's Law?Boyle’s law is a gas law that states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it.
The relation can be given as:

If chemical A has a toxicity level of one and chemical B has a toxicity level of two and the mixture of these two chemicals has a toxicity level of three, it means that the mixture of these two chemicals form a synergistic mixture. This is condition is known as synergism.
A synergistic effect is exerted when a greater effect is exerted than the added effect of both the chemicals together. This is applicable for toxic chemicals as well as non-toxic chemicals. Synergism can be dangerous in the case of both toxicology or chemicals in general.

A helium balloon has a volume of 2600 cm 3 when the temperature is 21°C. What is the
volume of the balloon when it's placed in a freezer with a temperature of -15°C?
Answer:
2,282 cm³
Explanation:
If all other variables are being held constant, you can find the new volume of the balloon using the Charles' Law equation. The equation looks like this:
V₁ / T₁ = V₂ / T₂
In this equation, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature. Before you can solve for the new volume, you need to convert Celsius to Kelvin (negative values do not work in this equation). This can be done by adding 273.15 to each temperature.
V₁ = 2600 cm³ V₂ = ? cm³
T₁ = 21 °C + 273.15 = 294.15 K T₂ = -15 °C + 273.15 = 258.15 K
V₁ / T₁ = V₂ / T₂ <----- Charles' Law
