Question

BALANCING EQUATION

$1. CH_{4} + O_{2} → CO_{2} + H_{2} O \\ 2. Na + Cl → NaCl \\ 3. Al + O_{2} → Al_{2} O_{3} \\ 4. N_{2} + H_{2} → NH_{3} \\ \ \ 5. Al + HCl → AlCl_{3} + H_{2} \\ \ \ 6. Fe + Cl_{2} → FeCl_{3} \\ \ 7. S_{8} + O_{2} → SO_{3}$
Pls answer fast ​

Answer 1

Answer:

balanced chemical is equation has equal numbers of atoms for each element ... For example, both product species in the example reaction, CO2 and H2O

Answer 2

Answer:

1.)CH4+O2=CO2+2H2O

2.)already balanced

3.)4Al+3O2=2(Al2O3)

4.)N2+3H2=2NH3

5.)
