Detailed explanation-1: -Magnesium (Mg) combines with chlorine (Cl2) to form a new product as magnesium chloride (MgCl2). Therefore it is a combination reaction and the balanced equation can be written as: Mg(s)+Cl2(g)→MgCl2(s)

Detailed explanation-2: -c. single displacement reaction. Which type of chemical reaction occurs in Ca + Cl2 → CaCl2?

Detailed explanation-3: -A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound. The starting materials are always pure elements, such as a pure zinc metal or hydrogen gas, plus an aqueous compound.

Detailed explanation-4: -The answer is a. single displacement reaction. Single displacement reactions are those that involve the replacement of an element in another compound. In the reaction given, magnesium metal reacts with hydrochloric acid resulting in the formation of magnesium chloride and hydrogen gas.
