Question

choose the best answers. 3. if the reactants of a chemical equation are na + cl₂, what can you assume about the products? a there will be a total of five atoms in the products. b there will be three atoms of sodium in the products. c there will be a total of three atoms in the products. d there will be two atoms of chlorine in the products.

Explanation:

Step1: Balance the chemical equation

The reaction is $2Na + Cl_2
ightarrow 2NaCl$.

Step2: Analyze the number of atoms in products

In $2NaCl$, there are 2 sodium atoms and 2 chlorine atoms, a total of 4 atoms. Initially, we had 1 sodium atom and 2 chlorine - atom in $Na + Cl_2$, but we need to balance the equation. After balancing, we can see that for the products of the reaction of $Na$ and $Cl_2$ (which is $NaCl$), there will be two atoms of chlorine in the products.

Answer:

D. There will be two atoms of chlorine in the products.
