Probably protons because when it changes it becomes a whole new element
Answer:
CaCl2 (aq) + K2CO3(aq) ---------> CaCO3(s) + 2KCl(aq)
Explanation:
We have the reactants as calcium chloride and potassium carbonate. Recall that we are expecting that the reaction will yield a precipitate. We must keep that in mind as we seek to write its balanced chemical reaction equation.
So we now have;
CaCl2 (aq) + K2CO3(aq) ---------> CaCO3(s) + 2KCl(aq)
Recall that the rule of balancing chemical reaction equation states that the number of atoms of each element on the right side of the reaction equation must be the same as the number of atoms of the same element on the left hand side of the reaction equation.
This fixed percent is called the definite proportion. Specifically, this phenomenon is states in the Law of Definite Proportions. According to John Dalton, all the individual elements making up the compound has a fixed ratio, whether in mass or in moles. For example, for any amount of H₂O, there will always be a fixed proportion of 2 H atoms: 1 O atom.
