How many moles of kmno4 can be produced from 0.886 moles of carbon dioxide?

To answer this question, you need to know the equation of the reaction. I think the equation should be

3K2MnO4 + 2 CO2 = 2 KMnO4 +1 MnO2 + 2 K2CO3 

If you look at the coefficient, for every 2 CO2 there will be 2 KMnO4 formed. The amount of KMnO4 formed for 0.886 CO2 with 100% yield would be:
2/2 * 0.886 moles= 0.886 moles

covalent bonds

Explanation:

Inter molecular forces are present between molecules.

Intra molecular forces are present in the molecule.

The Inter molecular forces further give strength to a substance. These are less stronger than intra molecular forces.

Here London dispersion forces , van der Waals forces , hydrogen bonds are inter molecular forces [between molecules]. While covalent bonds are intra molecular [within the molecule].

London dispersion forces are common to all matter.

Van der waals forces depends upon nature of the compound.

Hydrogen bonds are formed between hydrogen (bonded to F, O or N] and another atom of F, O or N.
