A student ran the following reaction in the laboratory at 765 K: N2(g) + 3H2(g) 2NH3(g)

When she introduced 3.79×10-2 moles of N2(g) and 6.76×10-2 moles of H2(g) into a 1.00 liter container, she found the equilibrium concentration of NH3(g) to be 8.42×10-4 M.

Calculate the equilibrium constant, Kc, she obtained for this reaction.

Kc=

they are both synthetic elements

explanation:

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
