Answer:
Q = 450 J
Explanation:
Given that,
Mass of a piece of glass, m = 45 g
The temperature changes from 10°C to 30°C.
The specific heat is 0.5 J/g°C
We need to find heat required to raise the temperature. The formula that is used to find it is given by :
So, the required heat is 450 J. Hence, the correct option is (c).
Answer:
b. The amount of SO3(g) decreases and the value for K increases.
Explanation:
Hello,
In this case, for the given reaction:
The change in the stoichiometric coefficient is:
In such a way, since the reagents have more moles than the products, based on Le Chatelier's principle, if the volume is increased, the side with more moles is favored. In addition, since the formation of reagent is favored, K is diminished based on the law of mass action shown below:
Therefore the answer is:
b. The amount of SO3(g) decreases and the value for K increases.
Best regards.
