Question

I need to balance these biology equations please help:

1. K + B2O3 ---> K2O + B
2. C + S8 ---> CS2
3. Na + O2 ---> Na2O2
4. N2 + O2 ---> N2O5
5. H2 + O2 ---> H2O2

Answer 1

Explanation:

1)6K+B2O3------3(K2O)+2B

2)4C+S8----------4(CS2)

3)2Na+O2---------Na2O2

4)2N2+5O2----------2(N2O5)

5)H2+O2-----------H2O2

Answer 2

1,,,6k+ B2O3,,,,,,,,,,,3(K2O)+ 2B

2,4C+S8,,,,,,,,,,,,,4(CS2)

3, 2NA+ O2,,,,,,NA2O2

4,,2N2+5O2,,,,,,,2(N2O5)

5,,,,H2 + O2,,,,,,,2H2O
