Which chemical equation is balanced? a) 2pcl5 + 2h2o → 2hcl + h3 po4 b) pcl5 + h2o → hcl + h3 po4 c) pcl5 + 3h2o → 5hcl + h3 po4 d) pcl5 + 4h2o → 5hcl + h3 po4

Option (D) is the correct answer.

Explanation:

A balanced equation is defined as the equation which contains same number of atoms on both reactant and product side.

For example,

Number of atoms on reactant side are as follows.

P = 1

Cl = 5

H = 8

O = 4

Number of atoms on product side are as follows.

P = 1

Cl = 5

H = 8

O = 4

Since, there are same number of atoms on both reactant and product side. Hence, this equation is balanced.

Thus, we can conclude that out of the given options , this chemical equation is balanced.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
