2 HCl + CaCO3 -> CaCl2 + H2O + CO2
In words, two moles of hydrochloric acid reacts with one mole of calcium carbonate to yield one mole of calcium chloride, one mole of water, and one mole of carbon dioxide.
The chemical equation is:K2CO3 + CaCl2 = CaCO3(s) + 2 KCl
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 balanced equation for this reaction is: 3H2 + N2 -> 2NH3
To write an ionic equation, first write the balanced chemical equation for the reaction. Then, separate the soluble ionic compounds into their respective ions. Finally, eliminate the spectator ions that do not participate in the reaction to form the net ionic equation.
The ionic equation for the reaction between calcium carbonate (CaCO3) and an acid is: CaCO3(s) + 2H+(aq) → Ca2+(aq) + H2O(l) + CO2(g). In this reaction, calcium carbonate reacts with acid to form calcium ions, water, and carbon dioxide gas.
The chemical equation is:K2CO3 + CaCl2 = CaCO3(s) + 2 KCl
Ca(OH)2 + CO2 -----> CaCO3 + H2O + 74 kJ/mol
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.
2h2 + o2 2h2o
An example is:2 KOH + H2SO4 = K2SO4 + 2 H2O

how do you write the balance equation of sucrose?
Ca(OH)2 + CO2 = CaCO3 + H2O

The substance 'x' could be calcium hydroxide (Ca(OH)2), commonly known as lime water. When exposed to CO2, it forms a white precipitate of calcium carbonate (CaCO3) and water. The balanced chemical equation for this reaction is: Ca(OH)2 + CO2 -> CaCO3 + H2O.
Phosphine is not very soluble in water compared to nonpolar substances. If you were to write a balanced equation for the reaction of PH3 with water, it would be an equilibrium reaction.
you have to write... 2KI + Cl2 = 2KCl + I2
