The equation shows the reaction of calcium oxide with water to produce calcium hydroxide.
CaO+H2O→Ca(OH)2 \text{CaO} + \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 CaO+H2O→Ca(OH)2Calculate the maximum mass of calcium hydroxide, Ca(OH)2\text{Ca(OH)}_2Ca(OH)2, that could be produced from 280 tonnes of calcium oxide, CaO\text{CaO}CaO. (Relative formula masses: CaO=56\text{CaO} = 56CaO=56, Ca(OH)2=74\text{Ca(OH)}_2 = 74Ca(OH)2=74)
