Answer:

C. 4

Explanation:

From the left hand(reaction) side of the equation hydrogen exist as a molecule in hydrogen sulfide(2H2S) . what this simply means it contain two atoms . Now multiplying the bold number in 2H2S with 2 atoms of hydrogen which constitute a molecule .it will give 4 . On the left Side hydrogen atom(2H2) is 4.

On the right(product) side where Hydrogen appear in the water molecules(2H20), multiply 2 by 2 (2H2) you will get 4 also.

so Hydrogen atom is 4 on both side of the equation.

Show that, with appropriate coefficients, the two reactions can be summed to give the overall oxidation of SO2 by O2 to give SO3

SIZIF [17.4K]

Answer:

See explanation

Explanation:

We know that the process of the oxidation of SO2 to SO3 is catalysed by NO2 gas. It occurs in two stages and i will show the balanced reaction equation of the both stages below;

Step 1

2NO2(g) + 2SO2(g) ------> 2NO(g) + 2SO3(g)

Step 2

2NO(g) + O2(g) -------> 2NO2(g)

So, the overall reaction equation is;

2SO2(g) + O2(g) ------> 2SO3(g)
