Question

Name the type of equation shown here: 2NaBr+Ca(OH)2 —>CaBr2+2NaOH

Answer 1

A) Double replacement
Because the reactants switch when they become products

Answer 2

Answer: A) double replacement

Explanation:

1. Double displacement reaction is one in which exchange of ions take place.  

Example: $2NaBr+Ca(OH)_2\rightarrow CaBr_2+2NaOH$

2. Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

Example: $Zn+2HCl\rightarrow ZnCl_2+H_2$

3. Combustion is a type of chemical reaction in which fuel is reacted with oxygen to form carbon dioxide and water.

Example:  

$C_6H_{12}O_6+O_2 \rightarrow CO_2+H_2O$

4. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.

Example: $Li_2O+CO_2\rightarrow Li_2CO_3$
