The ratio of H2 gas to O2 gas will always remain 2:1, and the ratio of H2 gas to H2O gas will remain 1:1 so if the gas volumes are measured at the same temperature and pressure: 44.8 liters of H2 + _____ liters of O2 → ____ liters of H2O

Answers

Answer 1
Answer:

Final answer:

Given 44.8 liters of H₂ gas, 22.4 liters of O₂ gas would be required for a complete reaction, producing 44.8 liters of H₂O gas. This conclusion is reached by leveraging Avogadro's law, ideal gas law, and understanding stoichiometry.

Explanation:

The question involves understanding how standard molar volumes and stoichiometry play into gas reactions. Avogadro's law states that the volume of a gas is directly proportional to the number of moles of the gas. Therefore, if you have 44.8 liters of H₂ gas, complying with Avogadro's law and the given ratios of gases as stated in the problem, you can conclude that to react completely, you would need 22.4 liters of O₂ gas, producing a total of 44.8 liters of H₂O gas as per reaction stoichiometry.

Avogadro's law is critical to understanding gas behavior and stoichiometry. Equally, understanding the concept of the ideal gas law is necessary to perform stoichiometric calculations involving gaseous substances.

Dalton's law of partial pressures also plays into calculations involving gaseous mixtures and helps to understand how different gases within a mixture interact. Overall, comprehending these concepts grants insights into gas behavior under varying temperature, pressure, and volume conditions and how gases react in chemically balanced equations.

Sulfur dioxide is a main component of: photochemical smog, thermal inversion, industrial smog.

Answers

Answer: industrial smog.

Explanation:

The industrial smog typically exists in the urban industrial areas where the large scale burning of the fossil fuels may lead to generation of huge amount of smoke and sulfur dioxide gas liberated into the atmosphere. These gaseous products gets mixed with the droplets of fog already present in the atmosphere. This lead to the formation of industrial smog. The industrial smog forms a thick blanket of smog or haze nearly close to the ground.

Final answer:

Sulfur dioxide is a primary component of industrial smog and photochemical smog, but it does not directly influence thermal inversion. It is released into the atmosphere predominantly from burning fossil fuels.

Explanation:

Sulfur dioxide is a significant component in the creation of both industrial smog and photochemical smog, two serious urban air pollutants. During industrial activities, fossil fuels such as coal and oil that contain sulfur are burned, releasing sulfur dioxide into the atmosphere. This gas then reacts with water vapor and other compounds to form industrial smog. In the case of photochemical smog, when sulfur dioxide interacts with sunlight, volatile organic compounds, and nitrogen oxides, it contributes to the formation of this harmful type of smog. However, sulfur dioxide does not directly relate to the occurrence of thermal inversion, a weather-related phenomenon that can trap smog and other pollutants close to the ground.

Which of the isotopes is the most abundant isotope in the sample?Cd-106
Cd-108
Cd-112
Cd-114
Cd-116

Answers

Answer: Cd-112

Explanation: to find out the most abundant isotope, look at the weighted average on the periodic table. the one closest to it in mass is going to be the most abundant isotope. in this case, the weighted average of cadmium is 112.411, so the answer is Cd-112.
