antacids which contain CaCO3 react with stomach acid to the equation . it gives the eq but I cant type it. what is the mass of stomach acid that reacts with 1.00 grams CaCO3 ?
It was later determined that each molecule of the unknown base could accept two protons. What is the molar mass of this unknown compound?
addition of excess NH3 to this acidic solution produces only a blue solution. Which group III ions are present, which are absent and which are in doubt? How would you remove all doubt?
what are the ground state electron configuration of the elements in period 2 of this alternate reality?
Solubility of calcite (CaCO3) will increase with a decrease in temperature and decrease with an increase in temperature. This is because the solubility of calcite is dependent on the solubility of CO2.
