this is true. hope i helped!
Answer:
CaCO3+2HCl=CaCl2+H2O+CO2 this is the balanced reaction occur between calcium carbonate and HCl to minimize the hyperacidity.
Explanation:
CaCO3 reacts with hydrochloric acid produced by oxytonic cells of the stomach to generate calcium chloride (CaCl2) and water(H2O) along with the release of carbon dioxide(CO2) gas.
This reaction helps to minimize hyperacidity.
Answer: a bench made of composite plastic
Explanation:
The chemical weathering can be defined as the process in which a chemical causes the degradation and decomposition of the rocks into small particles. The iron rods, feldspar, and marble will weather considerably with a greater danger as the have a strong solid body. But plastic when exposed to a chemical agent usually melts and thus there is least or no danger of chemical weathering of plastic.
