Answer:False
Explanation:
Kinda of a opinionated question, but unless you call -12 C warm then the answer is False
Explanation:
it reacts with acid .......
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)
<u><em>Explanation</em></u>
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.
