Ammonium nitrate, $\text{NH}_4\text{NO}_3$, is a fertiliser that is put on fields to promote crop growth. Slaked lime, $\text{Ca(OH)}_2$, is an alkali that is added to fields to decrease the acidity of the soil. Ammonium nitrate and slaked lime must not be applied to a field together because they react with each other and produce a gas, Z. What is the identity of Z?
- Aammonia
- Bhydrogen
- Cnitrogen
- Doxygen
