Question

_H2+_Cl2->_HCl fill in the blanks if necessary.

Answer 1

H₂ + Cl₂ → 2HCl

Step-by-step explanation:

The given reaction expression is shown below:

H₂ + Cl₂ → HCl

We are to balance this given reaction expression.

Let us do this mathematically;

aH₂ + bCl₂ → cHCl

Conserving H : 2a = c

Cl: 2b = c

Now, let a = 1, c = 2 , b = 1

So:

H₂ + Cl₂ → 2HCl
