Name the type of equation shown here: 3pb+2h3po4 ==> 3h2+pb3(po4)2 a. double replacement b. single replacement c. combustion d. synthesis

B.  single 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:
