I think it would be A because hazardous waste would most likely be found in dust, fumes etc. I'm not sure though.
i think it’s B. a hydrocarbon reacts with oxygen
if i’m correct, a combustion reaction is anything that’ll give a reaction
Balanced chemical equation is :

It is given that the equation is in equilibrium.
We need to find what will happen if we add more
is added .
By Le Chatelier's principle :
Changing the concentration of a chemical will shift the equilibrium to the side that would counter that change in concentration.
It means production of the side where content is added will decrease and concentration on other side will increase .
So , more NO would form .
Therefore, option B. is correct.
Hence, this is the required solution.
Weathering and erosion produce smaller rock particles which, when mixed with dust result in different types of soil.
