Subtract it's atomic number from it's mass number
Answer:
they identify factors that affect chemical processes then they determine the amount of substance produced or consumed then predict the amount of energy released or absorbed
I'm pretty sure the answer is Temperature
Answer:
300kg
Explanation: The question says about 30%, so I think it is 300kg
Solving this chemistry is a little bit hard because the question didn't give some important detailed.
So first, there are a couple problems with your question.
We will just need to know which direction will it proceed to reach equilibrium.
Your expression for Kc (and Qc ) for the reaction should be:
Kc = [C] / [A] [B]^2
You have not provided a value for Kc, so a value of Qc tells you absolutely nothing. Qc is only valuable in relation to a numerical value for Kc. If Qc = Kc, then the reaction is at equilibrium. If Q < K, the reaction will form more products to reach equilibrium, and if Q > Kc, the reaction will form more reactants.
