Answer:

2B2 + 3O2 → 2B2O3

Step-by-step 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!
