2Na + CaCl2 = 2NaCl + Ca. Just make sure same number of elements are on both sides.
HCl + NaOh -> H2O + NaCl No coefficients are needed because the number of atoms are present on each side by default. Mixing an acid and a base always makes water and a salt, thus the sodium chloride.
The balanced molecular equation is CaCl2 + Na2S -> CaS + 2NaCl. To write the ionic equation, we need to break down the reactants and products into their respective ions. This results in the ionic equation: Ca2+ + 2Cl- + 2Na+ + S2- -> CaS + 2Na+ + 2Cl-. Cross out spectator ions that appear on both sides of the equation to obtain the net ionic equation: Ca2+ + S2- -> CaS.
When NaHCO3 is combined with CaCl2 and H2O, a reaction will occur. However, the specific products depend on the conditions of the reaction - typically, NaHCO3 will react with CaCl2 to form NaCl, CaCO3, and H2O.
When CaCl2 reacts with NaHCO3, the products formed are CaCO3 (calcium carbonate), NaCl (sodium chloride), and H2O (water).
2NH4Cl + Na2CO3 --> 2NH3 + CO2 + H2O + 2NaCl
The answer is TWO (2)Na2CO3 + CaCl2 --> 2 NaCl + CaCO3
The balanced equation for CaSO4 + 2NaCl is CaCl2 + Na2SO4.

2NH4Cl + Na2CO3 --> 2NH3 + CO2 + H2O + 2NaCl
HCl + NaOH = H2O + NaCl is already balanced.
The balanced equation is: CaCl2 + H2CO3 -> CaCO3 + 2HCl. So, the coefficient needed is 2 in front of HCl to balance the reaction.
The balanced equation for the reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) is: 2HCl + CaCO3 -> CaCl2 + H2O + CO2.
Ca + Cl2 ---> CaCl2
The balanced equation for the reaction between calcium (Ca) and chlorine (Cl2) to form calcium chloride (CaCl2) is: 2Ca + Cl2 -> 2CaCl2
