Many over-the-counter antacid tablets are now formulated using calcium carbonate as the active ingredient, which enables such tablets to also be used as dietary calcium supplements. as an antacid for gastric hyperacidity, calcium carbonate reacts by combining with hydrochloric acid found in the stomach, producing a solution of calcium chloride, converting the stomach acid to water, and releasing carbon dioxide gas (which the person suffering from stomach problems may feel as a "burp"). write the balanced chemical equation for this process

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.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

i'm wiling to try and you : )
