How to Balance Potassium + Oxygen gas → Potassium oxide |
How to Balance: K + O2 → K2O
Type of Chemical Reaction: This is a combination reaction.
Word Equation: Potassium + Oxygen gas → Potassium oxide
| Balancing Strategies: In this equation we have potassium and oxygen gas combining to form potassium oxide. This is a combination reaction.
To balance the equation, the first thing to do is to change the coefficient in front of K2O if and and to balance the oxygen atoms. For a complete explanation, watch:
About Balancing Chemical EquationsWhen balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.Only change the coefficients (these are the numbers in front substances).
 Never change the subscripts (the small numbers after elements).
