CaCl2 + H2CO3 = CaCO3 + 2HCl
The molar ratios (coefficients) are 1:1::1:2
The balanced equation is: CaCl2 + H2CO3 -> CaCO3 + 2HCl. So, the coefficient needed is 2 in front of HCl to balance the reaction.
That's not a chemical equation. But I believe the coefficient (the number in front of HCl) is 1. Normally, when you write equations, you don't put the 1. It's just inferred.
The coefficient of HCl in the balanced equation is 2. This is because the balanced equation shows that 1 molecule of CaCl2 reacts with 1 molecule of H2CO3 to form 1 molecule of CaCO3 and 2 molecules of HCl.
Na2CO3 (aq) + CaCl2 (aq) -----> 2 NaCl(aq) + CaCO3(s) This is a double displacement reaction.
The balanced chemical equation for the reaction between HCl and CaCO3 is: 2HCl + CaCO3 → CaCl2 + H2O + CO2. The molar ratio between HCl and CaCl2 is 2:1. Calculate the number of moles of HCl from 14.6 g, then use the mole ratio to find the moles of CaCl2. Finally, convert moles of CaCl2 to grams.

The balanced equation is: CaCl2 + H2CO3 -> CaCO3 + 2HCl. So, the coefficient needed is 2 in front of HCl to balance the reaction.
The balanced chemical equation for the reaction between Na2CO3 and CaCl2 to form CaCO3 and NaCl is: Na2CO3 + CaCl2 -> CaCO3 + 2NaCl. Therefore, the coefficients are 1, 1, 1, and 2 for Na2CO3, CaCl2, CaCO3, and NaCl respectively.
That's not a chemical equation. But I believe the coefficient (the number in front of HCl) is 1. Normally, when you write equations, you don't put the 1. It's just inferred.
The overall equation is: CaCO3(s) + 2NaCl (aq) Na2CO3(aq) + CaCl2(aq),
The other side of the equation K2CO3 + CaCl2 is 2KCl + CaCO3.
The balanced equation for the reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) is: 2HCl + CaCO3 -> CaCl2 + H2O + CO2.
The answer is TWO (2)Na2CO3 + CaCl2 --> 2 NaCl + CaCO3
The coefficient of HCl in the balanced equation is 2. This is because the balanced equation shows that 1 molecule of CaCl2 reacts with 1 molecule of H2CO3 to form 1 molecule of CaCO3 and 2 molecules of HCl.
CaCO3 + 2HCl --> CaCl2 + H2O + CO2
The balanced chemical equation for the reaction between CaCO3 (calcium carbonate) and KCl (potassium chloride) is: CaCO3 + 2KCl -> CaCl2 + K2CO3
Na2CO3 (aq) + CaCl2 (aq) -----> 2 NaCl(aq) + CaCO3(s) This is a double displacement reaction.
