Answer:
There is 30.74% of carbon in dimethylsulfoxide
Answer:
C.
Explanation:
The mass of the reactants should not change, in fact it would be equal because the only thing that changes is the form in which your products are in. The reactants will still have the same amount of mass from the products as no products were removed or added, the structure changed, the mass did not.
The given balanced reaction is,
The stoichiometric coefficients of each element or compound represents the number of moles of that element or compound required for the complete reaction to take place.
The mole ratios of different products and reactants will be:
So the mole ratio comparing iron (Fe) and oxygen gas (
) is
4 : 3
I think the best answer is B. Even this is the broadest case for the Conservation of matter and the one for Energy, the only way this can be applied is in nuclear rxns.
Its a covalent bond formed by Potassium and Chlorine.
The product obtained is POTASSIUM CHLORIDE.
Hope this HELPS !!!
