Flauer [41]3 years ago
5 0

Hey there!

Na + O₂ → Na₂O

Balance O.

2 on the left, 1 on the right. Add a coefficient of 2 in front of Na₂O.

Na + O₂ → 2Na₂O

Balance Na.

1 on the left, 4 on the right. Add a coefficient of 4 in front of Na.

4Na + O₂ → 2Na₂O

Our final balanced equation: 4Na + O₂ → 2Na₂O

Hope this helps!

Answer:

2B2 + 3O2 → 2B2O3

Explanation:

Balance The Equation: B2 + O2 = B2O3

1. Label Each Compound With a Variable

  aB2 + bO2 = cB2O3

2. Create a System of Equations, One Per Element

  B: 2a + 0b = 2c

  O: 0a + 2b = 3c

3. Solve For All Variables (using substitution, gauss elimination, or a calculator)

  a = 2

  b = 3

  c = 2

4. Substitute Coefficients and Verify Result

  2B2 + 3O2 = 2B2O3

      L R

  B: 4 4 ✔️

  O: 6 6 ✔️

hope this helps!
