Question

for the chemical formula add coefficients then draw your finished product second equation

Answer 1

For the unbalanced equation:

$H_2+Cl_2\to HCl$

We can balance by checking how many of each element there is in both sides.

We need to have the same number of H and Cl on both sides.

For now, the equation has 2 H and 2 Cl on the left side and 1 H and 1 Cl on the right side.

If we leave the coefficients of H₂ and Cl₂ as 1 and put a coefficient of 2 on HCl, we will get:

$H_2+Cl_2\to2HCl$

Now, we have 2 H on both sides and 2 Cl on both sides, so the equation is balanced.

Thus, the alanced equation is:

$H_2+Cl_2\to2HCl$
