How to Balance K + O2 = K2O (Potassium + Oxygen gas)

To balance K + O2 = K2O you will need to be sure to count all of atoms on each side of the chemical equation.

Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Potassium + Oxygen gas .

Important tips for balancing chemical equations:

Only change the numbers in front of compounds (the coefficients).
Never change the numbers after atoms (the subscripts).
The number of each atom on both sides of the equation must be the same for the equation to be balanced.

Doesn't the K + O2 equation create KO2 tho?
And only after following reactions you get K2O?
KO2 + K = K2O2
K2O2 + 2K = 2K2O

why does the potassium have a small 2 on the products side?

[williamtaylor]

why does it become k2 though, I've been looking for an answer but all I'm getting is some waffle about vitamins and kidney stones.

Isn't potassium/Rb/Cs only form peroxide when reacted with O2 ?

So y’all don’t actually understand your teacher and ended searching for this video? (I’m talking about the people in the comments)
