How many species will have multiples of .2. in the following equation after balancing? Balanced equation must contain least integral multiples. `CrSCN^(2+) + BrO^(-)+OH^(-) rarr Br^(-)+ NO_(3)^(-1) +CO_(3)^(2-)+SO_(4)^(2-)+CrO_(4)^(2-)+H_2O`

Answer

5

Explanation

Balanced equation is
`2CrSCN^(-) +19BrO^(-) +18 OH^(-) rarr `
`19 Br^(-)+2NO_(3)^(-)2SO_(4)^(2-)+2CrO_(4)^(2-)+9H_2O`
Thus, five species have coefficient equal to 2.
