During this chemical reaction, the solution becomes B. colder. This is because the process of dissolving sal ammoniac absorbs thermal energy from the surroundings, resulting in a decrease in temperature.
Read the passage about a chemical reaction that absorbs or releases thermal energy. Then, follow the instructions below.
Sal ammoniac, a rare mineral made up of ammonium chloride
(NH4Cl)
, is usually found near the vents of active volcanos. To collect samples of sal ammoniac, geologists must work when the weather is dry. If rainwater falls on the sal ammoniac, the mineral quickly dissolves to form a solution of ammonium ions
(NH4+)
and chloride ions
(Cl−)
. The process of forming the ions absorbs thermal energy from the surroundings and converts it to chemical energy.
Complete the statement.
during this chemical reaction, the solution becomes
A.warmer
B colder
