The answer is; C
Fossil fuels are the remains of an organism that lived in the past and have been preserved or their impression has been preserved. Fossils are studied to identify the difference (genetic and phenotypic) between past and future related organism and are carbon dated to determine the time in which the organisms existed. The study of fossils is called paleontology.
Answer:coastal Oregon, Washington, British Columbia, and southern Alaska in North America
Explanation:the climate characteristics of the marine west coast is its west coast location in the midlatitudes. Here maritime polar air masses are constantly coming ashore bringing mild temperatures and high humidity. In some cases like northern Europe, warm ocean currents moderate the temperature of the site.

There will be more acid particles to interact with the limestone at higher concentrations hence the rate of reaction increases.
The question is incomplete but I will try to help you the much I can. If you have carried out the experiment properly, you will notice that the rate of reaction increases as the concentration of the acid increases.
This is because, if the amount of limestone is held constant and the concentration of acid is increased, there will be more acid particles to interact with the limestone at higher concentrations hence the reaction proceeds faster.
