Question

Mr. Peters’ class conducted a fun experiment during class. For homework, Jason had to analyze the data and make a conclusion. What should Jason conclude?
OBSERVATIONS_ A cloudy white substance is formed, tiny bubbles forming at the top, A sweet odor.
A.Several chemical changes occurred. I conclude that no chemical reaction occurred.

B.Several chemical changes occurred. I conclude that a chemical reaction took place.

C.Several chemical and physical changes took place. I conclude that there was no chemical reaction.

D.Several physical changes occurred. I conclude that a chemical reaction took place

Answer 1

Answer:

B. Several chemical changes occurred. I conclude that a chemical reaction took place.

Explanation:

Hello,

Chemical reactions are carried out when the composition of a substance radically change due to a typically exhibited bonds breaking in the reactants which leads to the formation of new substances called products.

In this case, since a cloudy substance is formed, the formation of a new product is substantiated as well as the tiny bubbles which suggest the release of an additional gas product which has a particular sweet odor.

In such a way, we sum up that "several chemical changes occurred. I conclude that a chemical reaction took place", therefore, the answer is B.

Best regards.

Answer 2

B.Several chemical changes occurred. I conclude that a chemical reaction took place

Explanation:

From the observation, Jason can conclude that several chemical changes occurred and a chemical reaction has taken place. In a chemical change, often times, new products are usually formed.

• A chemical change is one in which new kind of matter is formed.
• Chemical changes are products of chemical reactions.
• The rearrangement of atoms in reacting species and the formation of bonds leads to chemical reactions.
• Chemical changes are irreversible, no change in mass(mass is conserved) and they require considerable amount of energy.
