Answer:
Explanation:
The structure of the methane, CH4, molecule exhibits single covalent bonds. Covalent bonding involves the sharing of electrons. In the methane molecule, the four hydrogen atom share one electron each with the carbon atom
 
        
                    
             
        
        
        
Use the p table and take 2 times the atomic mass of Fe and then 3 times the atomic mass of C and 9 times the atomic mass of O 
So I know that O= 16×9
 C=12×3
 Fe= Then add all the products up to find molar mass
        
             
        
        
        
1) Reactions which<span> involves both a </span>reduction<span> process and a complementary </span>oxidation<span> process are called </span>oxidation-reduction.they <span>can't be double replacement reactions.</span>
Hence,
 WO3 + 3H2 ---> W + 3H2O is an oxidation-reduction reaction
