Question

How does the balanced chemical equation show the conservation of matter in this chemical reaction?

F2+2NaBr->2Naf+Br2

A.)There are fewer Na atoms in the reactants than in the products
B.)The compound NaF is a substance that is different from the compound NaBr
C.)The number of F atoms in the reactants equal the number of F atoms in the products
D.) There are more Br atoms in the reactants than in the products

also, please explain your answer. i dont understand this whatsoever

Answer 1

Step-by-step explanation:

Answer is C!

Answer 2

F₂ + 2NaBr→ 2NaF +Br₂

The chemical equation above show the conservation of matter because

The number of F atoms in the reactants equal the number of F atoms in the product (answer C)

Explanation

According to the law of mass of matter conservation, the number of atoms in the reactants side should be equal to number of atoms in products side.

For example in reaction above the number of F atoms in reactants side equal the number of F atoms in the products side.Therefore the equation above show the conservation of matter.
