To balance chemical equations, you need to ensure that there are the same number of each type of atom on both sides of the equation. Here's how you can balance the given equations:
Equation 1: KHF₂ ➡️ KF + H₂ + F₂
On the left side, you have one potassium (K), one hydrogen (H), and two fluorine (F) atoms. On the right side, you have one potassium (K), two hydrogen (H) atoms, and two fluorine (F) atoms.
To balance it, you can put a coefficient of 2 in front of KF on the right side:
KHF₂ ➡️ 2KF + H₂ + F₂
Now, both sides have the same number of each type of atom.
Equation 2: P4O10 + H₂O ➡️ H3PO4
On the left side, you have four phosphorus (P), ten oxygen (O), and two hydrogen (H) atoms. On the right side, you have three hydrogen (H), one phosphorus (P), and four oxygen (O) atoms.
To balance it, you can put coefficients to balance the number of atoms:
P4O10 + 6H₂O ➡️ 4H3PO4
Now, both sides have the same number of each type of atom.
