Final answer:
The statements that ammonia gas reacts with oxygen gas, nitric oxide gas and liquid water are produced, and platinum is used as a catalyst, are accurate. However, a specific unbalanced equation must be provided to assess the number of hydrogen atoms on both sides of the equation, but we can still determine the accuracy of statements using the provided balanced chemical equations.
Step-by-step explanation:
When examining the statements provided about chemical reactions, we can deduce the following:
- Ammonia gas reacts with oxygen gas. This is true as shown by the balanced equation 4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O(g), where ammonia gas (NH₃) reacts with oxygen gas (O₂) in the presence of a catalyst.
- Nitric oxide gas and liquid water are produced. This is accurate as indicated by the products of the reaction mentioned above.
- Platinum is used as a catalyst. This statement is accurate; platinum acts as a catalyst in the reaction of ammonia with oxygen gas.
- The equation must be balanced to make a correct statement about the conservation of atoms. The balanced equation for the synthesis of ammonia provided is 3H₂(g) + N₂(g) = 2NH₃(g), which shows the number of hydrogen atoms is the same on both sides of the equation.
- Information has been provided to determine the accuracy of descriptions relating to chemical reactions and balancing equations, particularly in the context of ammonia synthesis and its oxidation.
Therefore, the statements a, b, and c are accurate, while statement d is not applicable unless a specific unbalanced equation is provided for analysis. Statement e is incorrect, as we have information provided through various balanced chemical equations and reaction descriptions.
