Solution
The correct option is B Sodium hydroxide + calcium bromide → Calcium hydroxide + sodium bromide; calcium; 2
A word-equation shows change of reactants to products through an arrow placed between them. The reactants are written on the left-hand side with a plus sign (+) between them. Similarly, products are written on the right-hand side with a plus sign (+) between them. The arrowhead points towards the products, and shows the direction of the reaction.
The word equation for the given reaction will be written as:
Sodium hydroxide + calcium bromide → calcium hydroxide + sodium bromide.
In CaBr2, the valency of calcium is 2 and the valency of bromine is 1.
