Question

C + O2 = Mg+ O2 = K+O2=

Answer 1

C + O2 = CO2
2Mg + O2 = 2MgO
4K + O2 = 2K2O

Answer 2

It looks like you've written a series of chemical equations involving different elements and compounds. Let me break down each equation for you:

1. C + O2 → This equation seems incomplete. It appears to represent the combustion of carbon (C) with oxygen (O2) to form carbon dioxide (CO2). The balanced equation would be: C + O2 → CO2

2. Mg + O2 → This equation represents the reaction between magnesium (Mg) and oxygen (O2) to form magnesium oxide (MgO). The balanced equation is: 2Mg + O2 → 2MgO

3. K + O2 → This equation represents the reaction between potassium (K) and oxygen (O2) to form potassium oxide (K2O). The balanced equation is: 4K + O2 → 2K2O

Please note that the coefficients in the balanced equations indicate the relative quantities of reactants and products, ensuring that mass and charge are conserved during the chemical reactions.
