The balanced chemical equation for the reaction between HCl (hydrochloric acid) and H2O (water) is:
HCl + H2O → H3O+ + Cl-
This equation represents the dissociation of hydrochloric acid in water to form hydronium (H3O+) and chloride (Cl-) ions.
To balance the equation Cl2 + H2O = HCl + HClO3, you need to add coefficients to the molecules so there is an equal number of atoms on each side of the equation. The balanced equation is: 3Cl2 + 6H2O = 6HCl + 2HClO3.
To balance the chemical equation between hydrochloric acid (HCl) and sodium carbonate (Na2CO3), you first write the unbalanced equation: HCl + Na2CO3 -> NaCl + H2O + CO2. Then you balance the equation by ensuring the same number of each type of atom on both sides of the equation, which in this case would be: 2HCl + Na2CO3 -> 2NaCl + H2O + CO2.
The balanced equation for NaCO3 + HCl is: Na2CO3 + 2HCl -> 2NaCl + H2O + CO2. Balancing the equation involves making sure there are the same number of each type of atom on both the reactant and product sides.
NaOH(hydroxide) + HCl(acid) ---------> NaCl(salt) + H2O(water)
The molecular equation for the reaction between hydrochloric acid (HCl) and water (H2O) is: HCl + H2O -> H3O+ + Cl-
