Questions: 3 CaSO4 + 2 AlBr3 → 3 CaBr2 + Al2(SO4)3 Indicate if the reaction is synthesis, decomposition, single replacement double replacement or combustion

Solution Steps

To determine the type of chemical reaction, we need to analyze the reactants and products. The given reaction is:

\[ 3 \mathrm{CaSO}_{4} + 2 \mathrm{AlBr}_{3} \rightarrow 3 \mathrm{CaBr}_{2} + \mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3} \]

In this reaction, we have two compounds, \(\mathrm{CaSO}_{4}\) and \(\mathrm{AlBr}_{3}\), reacting to form two new compounds, \(\mathrm{CaBr}_{2}\) and \(\mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3}\).

This reaction involves the exchange of ions between two compounds, resulting in the formation of two new compounds. This is characteristic of a double replacement (or double displacement) reaction.
