A theory proposed by Harold Hotelling states that owners of nonrenewable resources will only produce that resource if it wills the yield will have more value than other financial instruments available in the market, such as interest bearing securities and bonds. This assumes such owners are only motivated by profit and that markets are efficient. The theory is used by economists to predict the price of nonrenewable resources like oil, based on prevailing interest rates.

Answer:
Quartz is not pure in this rock.
Explanation:
When quartz shows effervescence in contact with an acid, it means that it is not in its pure state, but rather related to other substances that may be cementing the quartz. This effectiveness is caused by substances that do not react like quartz, such as calcite.
In this case, we can conclude that in relation to the calcium-rich rock shown in the question above, the calcium is not pure, but it is likely to be related to calcite, or other material that does not react to acid.
