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.

let that person have a turn to speak : )

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
