What is the right equation for reactants if the product is MO (oxide of a metal)?
M + O2 = MO or M2 + O2 = MO

[chenbeier]

Neither nor. It is like to calculate fractions in mathematics, You have M and you have O₂ . How many M you need to get MO and how many of it you get?

I need 1 mole of M to get MO.
I have 1 mole of M.

[chenbeier]

But you have 1 mole O₂. So how many mole M you need and how many mole MO you get? Or other way around, if you only have 1 mole M, how many moles O₂ you need.

I need 1 mole of M
I have 1 mole of MO because the coefficient is 1 before MO. So I have a mole of MO

[chenbeier]

Please write the correct equation.

[IBM]

Please write the correct equation.

2M + O2 = 2MO

[chenbeier]

If you have only one mole M then it is.

M + 0.5 O₂ => MO 

The other half mole O₂ will be left.

Please write the correct equation.

2M + O2 = 2MO

Finally, yes this is correct but as everyone has been trying to point out to you this is 2 moles of metal M reacting with one mole of diatomic oxygen O₂ giving 2 moles of metal oxide MO.

Please write the correct equation.

2M + O2 = 2MO

Finally, yes this is correct but as everyone has been trying to point out to you this is 2 moles of metal M reacting with one mole of diatomic oxygen O₂ giving 2 moles of metal oxide MO.

You mean 1 mole of diatomic oxygen = 2 moles of monoatomic oxygen? Could you simplify this point, please?

[chenbeier]

Yes it is, but this was not the point.

[IBM]

Yes it is, but this was not the point.

Could you explain please what you mean by 'Yes it is, but this was not the point'?

[chenbeier]

You mean 1 mole of diatomic oxygen = 2 moles of monoatomic oxygen?

Yes it is.  But in this discussion is was not the point.

If you have 1 mole M and 1 mole O₂ and you get 1 mole MO,

then the equation is M + 0.5 O₂  MO

the other half O₂ will be left.

[IBM]

'Mg + 0.5 O2 = MgO"
1. Is here 1 mole of O atoms in the product = 0.5 moles of O atoms  + 0.5 moles of O atoms in the reactant?
'2Mg + O2 = 2MgO
2. is 2  moles of O atoms in the product = 1 mole of O atoms + 1 mole of O atoms = 1 mole of O2 molecules?
