Question

Use coefficients to balance the following chemical equation. Remember a balanced chemical equation has the same number of atoms of each element on each side of the equation. Hint: create a table on scratch paper to count your atoms on each side of the equation so_(g) + ___02(g) → _so, (g)​

Answer 1

Answer: The given equation is balanced as
`SO_(2)(g) + O_(2)(g) \rightarrow SO_(3)(g)`

Step-by-step explanation:

A chemical equation that contains same number of atoms on both reactant and product side are called balanced chemical equation.

For example,
`SO_(2)(g) + O_(2)(g) \rightarrow SO_(3)(g)`

Here, number of atoms on reactant side are as follows.

• S = 1

• O = 4

Number of atoms on product side are as follows.

• S = 1

• O = 3

To balance this equation, multiply
`SO_(2)` by 2 on reactant side and multiply
`SO_(3)` also by 2 on product side.

Hence, the equation will be rewritten as follows.

`2SO_(2)(g) + O_(2)(g) \rightarrow 2SO_(3)(g)`

Here, number of atoms on reactant side are as follows.

• S = 2

• O = 6

Number of atoms on product side are as follows.

• S = 2

• O = 6

As there are same number of atoms on both reactant and product side. So, this equation is a balanced equation.

Thus, we can conclude that the given equation is balanced as
`SO_(2)(g) + O_(2)(g) \rightarrow SO_(3)(g)`
