Question

For the following reactions, write out the BALANCED reaction.

calcium + chlorine -> calcium chloride:

a) Ca + Cl2 -> CaCl2
b) 2Ca + Cl2 -> 2CaCl2
c) Ca + 2Cl -> CaCl2
d) 2Ca + 2Cl -> 2CaCl2

Answer 1

The balanced reaction for the reaction between calcium and chlorine to form calcium chloride is 2Ca + Cl2 -> 2CaCl2.

Step-by-step explanation:

The balanced reaction for the reaction between calcium and chlorine to form calcium chloride is:

2Ca + Cl2 → 2CaCl2

In this reaction, two atoms of calcium react with one molecule of chlorine gas to produce two molecules of calcium chloride.
