Question

heating of lime stone gives carbon-dioxide and powered lime this is a chemical or exothermic or endothermic or chemical combination ???​

Answer 1

Answer:

The chemical and physical properties of limestone, especially when reasonably pure, make it highly sought after for hundreds of everyday uses. With salt and coal, it formed the main feedstock for the chemical industry until about 1914. It is still important today as shown by the wide range of uses in Tables 1 - 4 (Appendix). The chemistry is relatively straightforward and can be used to illustrate many types of simple reactions and properties. It is then possible to relate these to industrial and domestic applications (see Limestone in everyday life).
