Example:
CaCO3 + 2HCl = CaCl2 + CO2 + H2O
no reaction
Na2CO3 + Ca
Na(3)Co(2)+Ca
NaNO3+CaCl2->NaCl+Ca(NO3)2
This is a vigorous exothermic reaction.
The general reaction is Acid + Metal Carbonate -> Salt + Carbon Dioxide + Water Hope this helps!
A carbonate of Al or Mg can neutralize the acidity in the stomach.
Na(3)Co(2)+Ca
The resulting compounds of this reaction are a metal salt of the acid, water and carbon dioxide.
When metal is brought into contact with fruit juice, the reaction is that of mild corrosion. This is because of the chemical makeup of both substances.
The answer is during a metal reaction to acid, it makes salt and hydrogen. Another way is Acid + Metal > Metal Salt + Hydrogen
Since it is a double displacement and the products of the reaction would be sodium nitrate and calcium carbonate, the precipitate would be calcium carbonate. This is because this reaction is a solubility based reaction, and sodium nitrate is a soluble compound (every metal is soluble in nitrate, and sodium dissolves in almost everything too). Whereas calcium carbonate is insoluble, and therefore will remain solid and form the precipitate.
