Question

32. Balance the following skeleton equation as illustrated below. (Ref: 282-288)

Answer 1

Answer: H2 + Cl2 => 2HCl

Explanation: the equation is now balanced. 2 H and 2 Cl atoms both in the reactant and product side.

Answer 2

Answer:

1/2H2 (g) + 1/2Cl2 (g) —> HCl (g)

Explanation:

Step 1:

The equation for the reaction is given below:

H2 (g) + Cl2 (g) —> HCl (g)

Step 2:

Balancing the equation.

H2 (g) + Cl2 (g) —> HCl (g)

The above equation can be balanced as follow:

There are 2 atoms of H on the left side and 1 atom on right side. It can be balance by putting 1/2 in front of H as shown below:

1/2H2 (g) + Cl2 (g) —> HCl (g)

There are 2 atoms of Cl on the left side and 1 atom on the right side. It can be balance by putting 1/2 in front of Cl as shown below:

1/2H2 (g) + 1/2Cl2 (g) —> HCl (g)

Now we can see that the equation is balanced
