Answer:
K = [H₂]² [ O₂] / [H₂O]²
Explanation:
The equilibrium constant of any reaction can be written as,
K = [product]/ [reactant]
For given reaction:
Chemical equation:
2H₂O → 2H₂ + O₂
equilibrium constant:
K = [H₂] [ O₂] / [H₂O]
In stoichiometric calculations, we will put the coefficient of balanced equation in given equilibrium constant equation.
K = [H₂]² [ O₂] / [H₂O]²
Answer:
It changed by -7 degrees Celsius.
Explanation:
A the first one represents an exponential growth chart
Each and every mole of any substance = Avogadro's Number of them
Answer: B or C
Explanation: The question does not include the variable or steps Brian is using so either one could be correct. It has to be the one that he is controlling though. This is because a control group is used to rule out any alternate explanations. Therefore the answer should be the one that he is trying to test out.
