Name the type of equation shown here: 2nabr+ca(oh)2 —> cabr2+2naoh a) double replacement b) single replacement c) combustion d) synthesis

A) double replacement

Explanation:

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

Example:

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

Example:

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

Example:  

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

Example:  

answer: they produce more slow than unicellular organisms.
