the 2nd option is right...

THANKS!!

Answer 2

Answer: Option (d) is the correct answer.

Step-by-step explanation:

A balanced equation is an equation in which the number of atoms on reactant side are equal to the number of atoms on product side.

For example,
`Ca(OH)_(2) + HNO_(3) \rightarrow Ca(NO_(3))_(2) + H_(2)O`

Number of atoms on reactant side are as follows.

• Ca = 1

• O = 5

• H = 3

• N = 1

Number of atoms on product side are as follows.

• Ca = 1

• O = 7

• H = 2

• N = 2

Therefore, to balance the chemical equation multiply
`HNO_(3)` by 2 on reactant side and on product side multiply
`H_(2)O` by 2.

Hence, the balanced chemical equation will be as follows.

`Ca(OH)_(2) + 2HNO_(3) \rightarrow Ca(NO_(3))_(2) + 2H_(2)O`
