Answer 2

The chemical reactions you've provided seem to be incomplete. However, I can help you complete them and provide the balanced chemical equations. If you have specific reactants and products in mind, please provide them so that I can assist you better.

For instance, let's complete the first reaction:

NaCl + H2 → NaH + HCl

If you could provide the missing information for the other reactions, I'd be happy to help you balance and complete them as well.
