How do I balance the chemical equation Ca(s) +O2(g) =CaO(s)
2 answers:
Hey there!
Ca + O₂ → CaO
Balance O.
2 on the left, 1 on the right. Add a coefficient of 2 in front of CaO.
Ca + O₂ → 2 CaO
Balance Ca.
1 on the left, 2 on the right. Add a coefficient of 2 in front of Ca.
2 Ca + O₂ → 2 CaO
Our final balanced equation: 2 Ca + O₂ → 2 CaO
Hope this helps!
Answer:
2Ca(s) + O2(g) = 2CaO(s)
Explanation:
2 moles of calcium reacts with 1 mole of oxygen gas to yield 2 moles of calcium oxide.
Thus, the reaction shows the formation of calcium oxide when calcium metal burns in the presence of oxygen. This is also the laboratory preparation of calcium oxide from calcium and oxygen.
