moisture creates calcium to react with concrete
halite because the molecules within it react with the acid causing a bubbling reaction also Calcite and Dolomite when it is powered
Calcium nitrate and magnesium will not react since calcium is more reactive than magnesium and so, magnesium does not displace calcium (See Reactivity Series). However, if Calcium nitrate is in aqueous solution (dissolved in water), some bubbles may be seen when Magnesium is added to it, since the Magnesium would be reacting with the water and producing hydrogen bubbles.
what is a chemical change that could happen to an antacid tablet
Yes. Calcium will react vigorously with acid and even water.
"Calcium tablets" is a bit vague. If you put calcium metal in water it will form bubbles as the calcium reacts with water to form calcium hydroxide and hydrogen gas (the bubbles). If you put tablets of some calcium salt in water ... you'd need to be more specific about what it is for us to answer the question.

no
Yes. For instance, combining hydrochloric acid and calcium carbonate creates calcium chloride, water, and carbon dioxide gas.
Both of these substances are alkaline and they react with excess acid in the stomach to produce a Calcium or Magnesium salt solution and Carbon dioxide gas.
Calcium chloride will not further react with chloride ions.
Yes. Calcium will react vigorously with acid and even water.
Calcium Hydroxide (Alkali in the stomach) and Gastric Acid (in the stomach)
Calcium carbonate and sodium chloride doesn't react.
