A chemist conducted a study on ammonia NH3(g) into hydrogen gas and nitrogen gas. This reaction is represented by the following balanced equation:

2 NH3(g) à N2(g) + 3 H2(g)

The rate of consumption of ammonia gas was determined to be 0.0036 mol/(Ls). What is the rate of formation for hydrogen gas in the experiment?

a. a primary source combines several different accounts of an event. b. a primary source generally benefits from having been written after an event.

explanation:

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

gas

explanation:

smoke is the matter of a gas
