Final answer:
The reactants in the given chemical equation are Calcium (Ca) and Iron(III) chloride (FeCl3), while the products are Calcium chloride (CaCl2) and Iron (Fe). The balanced chemical equation represents how these reactants combine to form the products.
Step-by-step explanation:
To identify the reactants and products of the chemical equation: 3Ca + 2FeCl3 -> 3CaCl2 + 2Fe, we start by writing the correct formulas for the substances involved.
Identify the reactants and the products in the reaction.
Reactants: Calcium (Ca) and Iron(III) chloride (FeCl3)
Products: Calcium chloride (CaCl2) and Iron (Fe)
Write the equation with the reactants on the left of the arrow and the products on the right. The balanced equation gives us the ratio in which the substances react and form products:
3Ca(s) + 2FeCl3(s) -> 3CaCl2(s) + 2Fe(s)
This equation shows that three atoms of calcium (Ca) react with two formula units of iron(III) chloride (FeCl3) to produce three formula units of calcium chloride (CaCl2) and two atoms of iron (Fe).
