Please check to see if I got these right and specifically for #2, I am not sure if I have this balanced correctly.
Write the complete balanced equations for the following:
1) Potassium metal reacts with oxygen gas to form solid potassium oxide. My answer:
4K(s)+O2(g)=4KO2(s)

2) Carbon monoxide gas and oxygen gas combine to form carbon dioxide gas. My answer: 2CO(g)+ O2(g)= CO2(g)
Is that right?

  • Chemistry - ,

    K+O2 >> K2O you balance.
    second is right, but not balanced, need a 2CO2 to balance.
