In which of the following chemical equations, the abbreviations repres...

Explanation:

Correct Option:
C. 2 H2 (g) + O2 (g) → 2 H2O (g)

Explanation:

- State Symbols: The state symbols used in chemical equations represent the physical state of the reactants and products involved in the reaction. The most common state symbols are (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous solutions.

- Given Equation: 2 H2 (g) + O2 (g) → 2 H2O (g)

- Interpretation: In the given chemical equation, the reactants hydrogen gas (H2) and oxygen gas (O2) are both in the gaseous state, which is represented by (g). The products formed, water (H2O), is also in the gaseous state, as indicated by the (g) state symbol.

- Explanation of Correctness: At reaction temperature, hydrogen and oxygen exist as gases, and when they react to form water, the resulting water vapor is also in the gaseous state. Therefore, option C is the correct representation of the chemical equation with the appropriate state symbols for the reactants and products involved.

In summary, the correct option is C, where all reactants and products are correctly represented in the gaseous state.
