Chemistry - Mole Concept Question with Solution | TestHub

Calcium cyanamide ($CaC{N}_2$), also known as nitrolim, is used primarily as a fertilizer. The hydrolysis reaction is slow and occurs in moist soil:

$CaC{N}_2+3H_{2}O\to CaC{O}_3+2N{H}_3$

For nitrolim:

100 g of nitrolim undergoes complete hydrolysis and releases $N{H}_3$ at a rate of 2 g per day. Nitrolim is considered better than urea ($CO(N{H}_2{)}_2$) for restoring soil health and reducing water pollution.

$CO(N{H}_2{)}_2+H_{2}O\to C{O}_2+2N{H}_3$

For urea:

100 g of urea undergoes complete hydrolysis and releases $N{H}_3$ at a rate of 10 g per day.

An ideal fertilizer mixture containing nitrolim and urea is prepared such that the amount of $N{H}_3$ released in one day is completely absorbed by the soil, resulting in zero water pollution.

Soil requirement of $N{H}_3=5$ g per day.

Which of the following statement(s) is/are incorrect?
