Select the chemical equation that most likely represents the reaction between the vinegar and the dolomite.
MgCO3 + 2HCH3COOMg+CO3 +(CH3COO + H2O
MgCO3 + 2HCH2COO → Mg(CH2COO)2 + CO2 +H2O
MgCO3 + 2HCH3COO → Mg(CH3COO)2 +H2O
MgCO3 + 2HCH3COO → Mg(CH2COO)2 + CO2

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?
