Question

HCl+MgO2=Cl2+MgCl+H2O

Answer 1

пероксид магния + хлороводород = хлорид магния + вода + дихлор

Answer 2

The chemical equation you've written is not balanced. Let's balance it:

HCl + MgO₂ → Cl₂ + MgCl₂ + H₂O

To balance this equation, we need to make sure that the same number of each type of atom is present on both sides of the equation. Here's the balanced equation:

2HCl + MgO₂ → Cl₂ + MgCl₂ + H₂O

Now, let's count the atoms to verify that it's balanced:

On the left side:

• 2 hydrogen (H) atoms
• 2 chlorine (Cl) atoms
• 1 magnesium (Mg) atom
• 2 oxygen (O) atoms

On the right side:

• 2 chlorine (Cl) atoms
• 1 magnesium (Mg) atom
• 2 oxygen (O) atoms
• 2 hydrogen (H) atoms

All the atom counts are equal on both sides, so the equation is balanced.
