The balance the equation for a half-reaction that occurs in acidic solution is given as,
→
The half-reaction method to balance redox reactions in acidic aqueous solutions follows rule.
- Balance elements in the equation other than O and H.
- Balance the oxygen atoms by adding the appropriate number of water opposite side of the equation.
- Balance the hydrogen atoms by adding proton ions ( ion) to the opposite side of the equation
- Add up charge on each side of the equation by adding enough number of electrons to more positive side.
- The on each side must be equal . Multiply by appropriate integers if they are nit equal.
- The half -equation are added together, by cancelling out the electrons to form one balanced equation.

1. They are isotopes of oxygen
2. they have the same number of protons and electrons
Answer:
15 moles of hydrogen gas are needed to react with 15 moles of chlorine gas.
Explanation:
The balanced reaction is:
H₂ (g) + Cl₂ (g) → 2 HCl (g)
By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of the compounds participate in the reaction:
- H₂: 1 mole
- Cl₂: 1 mole
- HCl: 2 moles
Then you can apply the following rule of three: If 1 mole of Cl₂ reacts with 1 mole of H₂, 15 moles of Cl₂ with how many moles of H₂ does it react?
moles of H₂= 15
<u><em>15 moles of hydrogen gas are needed to react with 15 moles of chlorine gas.</em></u>
