Question:

Complete the following reaction and balance it, and identify whether it is a single or double reaction, synthesis, combusting

$$\mathrm{K_2Cr_2O_7} + \mathrm{Li_3PO_4} \rightarrow$$

Answer:

The following reaction is a reaction between two salts:

$$\mathrm{K_2Cr_2O_7} + \mathrm{Li_3PO_4} \rightarrow \mathrm{K_3PO_4} + \mathrm{Li_2Cr_2O_7}$$

$\mathrm{Li_2Cr_2O_7}$ is a precipitate. The reaction can be balanced in the following way:

$$3\mathrm{K_2Cr_2O_7} + 2\mathrm{Li_3PO_4} \rightarrow 2\mathrm{K_3PO_4} + 3\mathrm{Li_2Cr_2O_7}$$

It is a double displacement reaction because two salts are changing their anions and cations: AB + CD → AD + CB.
