What are the coefficients when the chemical equation below is balanced? ___ FeS + O2 = ___ Fe2O3 + ___ SO2
Select one:
a)1, 1, 1, 1
b)4, 6, 1, 2
c)4, 7, 2, 4
d)2, 3, 1, 2

c)4, 7, 2, 4

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken.

In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.

The balanced chemical equation will be :

The coefficients when the chemical equation below is balanced are 4, 7, 2, 4

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
