Part 1: Name the type of chemical reaction that occurs when magnesium chloride solution (MgCl2) reacts with sodium carbonate solution (Na2CO3). Part 2: Explain why aluminum (Al) would react with copper chloride (CuCl2) but not with magnesium chloride (MgCl2).

Part 1: double replacement reaction

Part 2: Because on the activity series, Aluminum is above copper meaning it is stronger and can kick copper out. but aluminum is underneath magnesium meaning it is weaker so it isn't able to kick Mg out, so there was no reaction.

Explanation:

When MgCl2 react with Na2CO3 it gives MgCO3 and NaCl as products. It proceed as a double replacment reaction.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

you gotta add the following molecules so we can give u an answer
