Hello!
To answer your question lets go over what Chemical Sedimentary Rock is.
Chemical Sedimentary Rocks are formed by the cementation, saturation and deposition of minerals in the solution causing them to be inorganic and preciptate.
The most known example of this is rock salt.
Of the list you have provided of possible examples the following are defined as chemical sedimentary rock:
- Rock Salt
- Iron Ore
- SOME limestones
I hope this helps in answering your question.

Explanation:
A major problem with using 15 years of data to predict 100 years of data is that the 15 years could have been setting a trend, then level off.
For example, if the 15 years of data was a graph, and it was going up every year, then what if 20 years into the 100 years it stops going up? Then that means the data was invalid because there wasn't enough to base any trends off of.
You can prevent this from happening by extending the collection time of data and to reduce the amount of time that the data will be used to predict.
Hope this helps!
One way in which the study of populations ( human populations - I assume) affects us is that they can help predict the population size in the future and prepare us for it. For example, if we see that the population is decreasing, a country might want to consider supporting child-bearing or immigration to avoid the problem of too many people receiving pensions but not paying taxes.
