Question

Which type of chemical reaction occurs in Ca + Cl2 +CaCl2?

Answer 1

Answer: The correct answer is synthesis reaction.

Explanation:

Synthesis reaction is defined as the reaction in which two substances in their elemental state combine together to form a single molecule.

$A+B\rightarrow AB$

Combustion reaction is defined as the reaction in which hydrocarbon in the presence of oxygen decomposes to form carbon dioxide and water molecule.

$\text{Hydrocarbon }+O_2\rightarrow CO_2+H_2O$

Single replacement reaction is defined as the reaction in which more reactive element replaces a less reactive element from its chemical reaction.

$A+BX\rightarrow AX+B$

Double replacement reaction is defined as the reaction in which exchange of ions takes place.

$AB+CD\rightarrow CB+AD$

For the reaction given:

$Ca(s)+Cl_2(g)\rightarrow CaCl_2(s)$

This reaction is a type of synthesis reaction because calcium and chlorine reacts to form calcium chloride.

Answer 2

almost positive that its synthesis
