Question

Match the reaction to the type that best describes it.NaCl + KBr NaBr + KClMg + FeCl2 Fe + MgCl22H2O 2H2 + O2N2 + O2 2NO?Combination?Decomposition?Single replacement

Answer 1

Reaction 1: NaCl + KBr > NaBr + KCl - double replacement reaction

Reaction 2: Mg + FeCl2 > Fe + MgCl2 - single replacement reaction

Reaction 3: 2H2O 2H2 + O2 - decomposition reaction

Reaction 4: N2 + O2 2NO - combination reaction
