When wood combines with oxygen and burns, ashes and carbon dioxide are produced. How does the Law of Conservation of Matter relate to this observation? A. The mass of the wood will be destroyed.
B. The weight of these substances will change but the mass will stay the same.
C. The mass of each of these substances will be the same before and after the reaction.
D. The mass of the wood and the oxygen burned will equal the mass of the ashes and the carbon dioxide produced during the reaction.

Option C

Explanation:

Conservation of matter states that matter can not be created nor it can be destroyed. It can only be changed from one form to the other.

In this case, the matter contained is wood (solid) is converted into ash (solid) and carbon dioxide (gas).

The amount of all substances remains constant irrespective of any condition during a chemical reaction

Hence, option C is correct

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
