Answer:

One mole of water was produced from this reaction.

Explanation:

According to this question, the following equation is given as follows:

2H2 + O2 → 2H2O

Two (2) moles of hydrogen gas produces two (2) moles of water in this balanced chemical equation.

If 1 mole of hydrogen gas was used, then:

1 × 2/2 moles of water would be produced

1 mole of water would be produced.

Answer:

2.1 M is the molarity of the HCl solution.

Explanation:

$HCl+NaOH\rightarrow H_2O+NaCl$

Molarity of HCl solution = $M_1=?$

Volume of HCl solution = $V_1=50.0mL$

Ionizable hydrogen ions in HCl = $n_1=1$

Molarity of NaOH solution = $M_2=1.05 M$

Volume of NaOH solution = $V_2=100.0 mL$

Ionizable hydroxide ions in NaOH = $n_2=1$

$n_1M_1V_1=n_2M_2V_2$ (neutralization )

$M_1=\frac{M_2V_2}{V_1}=\frac{1.05M\times 100.0 mL}{50.0 mL}$

$M_1=2.1 M$

2.1 M is the molarity of the HCl solution.
