Question

predict which of the following hydrides is a gas or a solid a) HCl b) NaH. give reasons

Answer 1

hey buddy !! here's your answer...

✔️NaH is a solid as the ions Na+ and H- are held together by strong electrostatic forces but it's not so in HCl.
therefore HCl is a gas...

hope it helps !! ❤️✌️

Answer 2

HCl keep up the two different gases that easily produce the hydrogen gas.  

This one acts as the best dehydrating agent that ideal for the organic solvents.  

NaH is the solid that produces the ions like Na+ and H-.

They are mixed together and produce the excellent electrostatic force.

The hydrides are suitable for the metallurgical process.
