Answer:
C. HCI(g)
Explanation:
The following equation between hydrogen gas (H2) and oxygen gas (O2) is given below:
H2(g) + Cl2(g) ►
Based on these unbalanced equation, the products of the reaction was not given, however, if one molecule of hydrogen and oxygen combine, hydrogen chloride (HCl) should be produced as the product of the reaction as in:
H2(g) + Cl2(9) ► 2HCl(g)
