H2 + Cl2 --> 2HCl
It is already balanced, you have the same number of H's and the same number of Cl's in each side of the equation.
The balanced equation for the reaction between zinc and hydrochloric acid (HCl) is: Zn + 2HCl -> ZnCl2 + H2.
It is called dissolving the acid. balanced equation: HCl+H(OH)-> H+Cl+H(OH)
The balanced equation is 2HCl + Na2S → H2S + 2NaCl. This is balanced as the number of atoms of each element is the same on both sides of the equation.
1 HCl + 1 NaOH ---> 1 NaCl + 1 H(OH)
The reaction between K₂S and HCl forms KCl and H₂S gas. The balanced chemical equation is: K₂S + 2HCl → 2KCl + H₂S.
the term 'balanced' in science refers to balancing an equation. For example, if your equation is HCl --> (yields) H + Cl, there has to be an equal amount of H and Cl on both sides of the equation, making it balanced.
The chemical equation is:Na + OH- + H+ + Cl- = Na+ + Cl- + H2O(l)
The name is potassium carbonate, but there's NO (balanced) equation for just one compound. An equation is about a reaction e.g. synthesis or decomposition of K2CO3. This should be clearly stated in a question. Please rephrase it.
There is no reaction, because all product ( if reaction goes) would be soluble. so : H+ + Cl- + K+ + I- = H+ + Cl- + K+ + I- and than all of them dare present as a ions only.
The correct balanced chemical equation for the reaction between zinc (Zn) and hydrochloric acid (HCl) is: Zn + 2HCl → ZnCl2 + H2 This reaction produces zinc chloride (ZnCl2) and hydrogen gas (H2).
2H2 + O2 --> 2H2O
