Translate the following word equations into formula equations: 1: iron (III) oxide decomposes into iron metal and oxygen gas 2: magnesium nitrate reacts with lithium sulfate to produce lithium nitrate and magnesium sulfate

1. The word equation "iron (III) oxide decomposes into iron metal and oxygen gas" can be translated into the formula equation as follows:<br /><br />2Fe2O3(s) → 4Fe(s) + 3O2(g)<br /><br />In this equation, Fe2O3 represents iron (III) oxide, Fe represents iron metal, and O2 represents oxygen gas.<br /><br />2. The word equation "magnesium nitrate reacts with lithium sulfate to produce lithium nitrate and magnesium sulfate" can be translated into the formula equation as follows:<br /><br />Mg(NO3)2(aq) + Li2SO4(aq) → 2LiNO3(aq) + MgSO4(aq)<br /><br />In this equation, Mg(NO3)2 represents magnesium nitrate, Li2SO4 represents lithium sulfate, LiNO3 represents lithium nitrate, and MgSO4 represents magnesium sulfate.
