Section 1:
Complete these word equations with the missing chemical names.
(1) magnesium + hydrochloric  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater ==> magnesium chloride +  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater
(2) carbon +  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater ==> carbon dioxide
(3) potassium hydroxide + sulfuric acid ==>  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater + water
(4) magnesium carbonate + hydrochloric acid ==> magnesium chloride +  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater + carbon dioxide

Balance the following symbol equations with the missing numbers, symbols or formula. For software reasons subscript numbers in formulae have to be entered in separate boxes.
(5) Fe + CuSO₄ ==>  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater _{24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater} + Cu
(6) 2 24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater + O₂ ==>  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewaterMgO
(7)  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewaterH₂ + O₂ ==>  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewaterH₂O
(8) C + CO₂ ==>  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewaterCO
(9) Cl₂ + H₂ ==> 2 24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater
(10)  24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater + HCl ==> NaCl + H _{24acidFeSOHClhydrogenMgNaOHoxygenpotassiumsulfatewater}O
