Answer:
d. decomposition
Explanation:
decomposition reaction is a reaction in which a compound breaks down into 2 or more substances.
the general form is: AB → A + B
Answer:
The molarity of the solution is 0.29 
Explanation:
Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.
Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:

Molarity is expressed in units
.
In this case:
- number of moles of solute= 2.1 moles
- volume= 7.3 liters
Replacing:

Molarity= 0.29 
<u><em>The molarity of the solution is 0.29 </em></u>
