Answer 1

Метан,Гелий,Водород.

2H2+O2=2H2O

CH4+2O2=CO2+2H2O

4He+O2=He4O2

Answer 2

Composition of Uranus' Atmosphere

The atmosphere of the planet Uranus is primarily composed of three gaseous substances: A, B, and V. The known information about these substances is as follows:

- Substance A has a molecular mass that is 16 times lighter than the molecular mass of oxygen. - Substance B has a molecular mass that is 8 times lighter than the molecular mass of oxygen. - Substance V does not interact with oxygen. - The volumetric proportions of these substances in Uranus' atmosphere are 2%, 83%, and 15% respectively.

Identification of Substances in Uranus' Atmosphere

Based on the given information, we can identify the substances present in Uranus' atmosphere and write the equations for the reactions between gases A and B with oxygen.

1. Substance A: - Molecular mass: 16 times lighter than oxygen. - Reacts with oxygen to form carbon dioxide (CO2) and water (H2O).

Equation: A + O2 → CO2 + H2O.

2. Substance B: - Molecular mass: 8 times lighter than oxygen. - Does not react with oxygen.

Equation: No reaction with oxygen.

3. Substance V: - Does not interact with oxygen.

Equation: No reaction with oxygen.

Therefore, the substances present in Uranus' atmosphere are: - Substance A, which reacts with oxygen to form carbon dioxide and water. - Substance B, which does not react with oxygen. - Substance V, which does not interact with oxygen.

Presence of Substances A, B, and V in Earth's Atmosphere

The given information does not provide any details about the presence of substances A, B, and V in Earth's atmosphere. Therefore, we cannot determine if these substances are present in Earth's atmosphere based on the provided information.

Mass Fractions of Gases A, B, and V in Uranus' Atmosphere

The volumetric proportions of the substances in Uranus' atmosphere are given as 2%, 83%, and 15% for substances A, B, and V respectively. However, the question asks for the mass fractions of gases A, B, and V in Uranus' atmosphere.

To determine the mass fractions, we need additional information such as the molar masses of substances A, B, and V. Unfortunately, the given information does not provide the molar masses of these substances. Without this information, we cannot calculate the mass fractions of gases A, B, and V in Uranus' atmosphere.
