How would you calculate the amount of heat transferred when 3.55 g of Mg(s) react at constant pressure? How many grams of MgO is produced during an enthalpy change of -234 kJ? Consider the following reaction: 2Mg(s) + O2(g) → 2MgO(s) ΔH=−1204kJ
Consider the following reaction: 2Mg(s)+O2(g)â2MgO(s)ÎH=â1204kJ
1. Calculate the amount of heat transferred when 3.54 g of Mg(s) reacts at constant pressure.
2. How many grams of MgO are produced during an enthalpy change of -235 kJ ?
3. How many kilojoules of heat are absorbed when 40.8 g of MgO(s) is decomposed into Mg(s) and O2(g) at constant pressure?
