In the image, a chemistry problem is presented. The task is to complete the chemical reactions:

1. \( \text{Na} + \text{HCl} \rightarrow \)

2. \(\text{Реакция на получение водорода с помощью сплава $\text{SnH}_4$ и нашатыря = $\text{NH}_3$}\)

Solutions:

1. \( \text{Na} + \text{HCl} \rightarrow \text{NaCl} + \text{H}_2 \)

2. The second reaction describes producing hydrogen using a hydride and ammonia (\(\text{NH}_3\)). The specific equation isn't provided, but typically, a metal hydride in reaction with an acid or other substance can release hydrogen gas. However, further context is needed for a precise equation.
