What is the balanced chemical equation for the reaction of solid calcium metal and aqueous aluminum nitrate?

3 Ca(s) + 2 Al(NO₃)₃(aq) ⇒ 3 Ca(NO₃)₂(aq) + 2 Al(s)

Explanation:

Let's consider the single displacement reaction between solid calcium metal and aqueous aluminum nitrate. The unbalanced chemical equation is:

Ca(s) + Al(NO₃)₃(aq) ⇒ Ca(NO₃)₂(aq) + Al(s)

We have 3 nitrates on the left and 2 nitrates on the right, so we will multiply Al(NO₃)₃(aq) and Ca(NO₃)₂(aq) by 2 and 3, respectively, to balance them.

Ca(s) + 2 Al(NO₃)₃(aq) ⇒ 3 Ca(NO₃)₂(aq) + Al(s)

Finally, we have to add coefficients before Ca(s) and Al(s) to balance the equation.

3 Ca(s) + 2 Al(NO₃)₃(aq) ⇒ 3 Ca(NO₃)₂(aq) + 2 Al(s)

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
