Enter a balanced equation for the dissolution of caco3.
Tatiana [17]

Answer:

CaCO3(aq) → Ca2+(aq ) + CO3 2-(aq)

Explanation:

  • Dissolution reactions are reactions that occur when a solute either in gaseous, liquid, or solid form dissolves in a solvent such as water to form a solution.
  • In this case we are given Calcium carbonate (CaCO3) which undergoes dissolution according to the equation;
  • CaCO3(aq) → Ca2+(aq ) + CO3 2-(aq)
  • Then<em><u> the bicarbonate ion combines with two protons from water to form a weak acid H2CO3. The weak acid is then broken down to form CO2 and H2O since its unstable.</u></em>

They pull of push without actually touching the body. The charged particles interact by pulling or pushing the uncharged particles.

These charges are released when they come closer to some uncharged or other charged particles like the electrostatic charges. It is the charge build up in an area.
