: Phương trình H+ + OH- -> H2O là phương trình ion rút gọn của phản ứng nào sau đây? * H2SO4 + Ba(OH)2 -> BaSO4 + 2H2O
HCl + Cu(OH)2 -> CuCl2 + H2O
CH3COOH + NaOH -> CH3COONa + H2O
HNO3 +NaOH -> NaNO3 + H2O

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
