Question

Na (g) + 2HCl (g) -> H2 (g) + 2NaCl (s) is a balanced equation? True or false?

Answer 1

False, the given equation is not balanced.

Step-by-step explanation:

The given equation is:

Na(g) + 2HCl(g) → H₂(g) + 2NaCl(s)

And it is not balanced, the number of atoms of Na is not the same on both sides of the equation.

The balanced equation is:

2Na(g) + 2HCl(g) → H₂(g) + 2NaCl(s)

Now, the given equation is balanced, we have the same number of atoms on both sides of the equation.

Therefore, the answer is false, the given equation is not balanced.

I hope it helps you!
