Answer:
A geologist would observe how the material that the sculpture is made out of reacts to the acid.
<span>The formula actual yield /
theoretical yield is used to calculate the percent yield of a reaction.
This value is a measure of how much product is produced relative to the what is
supposed to be produced. It seems that the given in the problem is incomplete so we cannot really give a specific value. </span>
Answer:
Anhydride, any chemical compound obtained, either in practice or in principle, by the elimination of water from another compound. Examples of inorganic anhydrides are sulfur trioxide, SO3, which is derived from sulfuric acid, and calcium oxide, CaO, derived from calcium hydroxide
Explanation:
