Choose the chemical equation that is correctly balanced. 2Ca(s) + Cl2(g) → CaCl2(s) 2Mg(s) + O2(g) → 2MgO(s) Li(s) + Cl2(g) → 2L

iCl(s) 2C(s) + O2(g) → CO2(g)

Answer:

2Mg(s) + O₂(g) → 2MgO(s)

Explanation:

2Ca(s) + Cl₂(g) → CaCl₂(s) (incorrect)

Ca(s) + Cl₂(g) → CaCl₂(s) (correct)

Li(s) + Cl₂(g) → 2LiCl(s) (incorrect)

2Li(s) + Cl₂(g) → 2LiCl(s) (correct)

2C(s) + O₂(g) → CO₂(g) (incorrect)

C(s) + O₂(g) → CO₂(g) (correct)

Answer:

2Mg(s) + O2(g) → 2MgO(s) Li(s)

Explanation:

because adding those 2 compounds if u see on the product oxygen would have a subcript of 2 but since it's being multiplied by 2 that overtakes the subcript.. Also for whoever still confuse or need help in that watch that video i saw it and understood better how to define a balanced and unbalanced equation =)
