Answer:
No, (But it is all that is the only way out of world war3)
Explanation:
If they take over Ukraine, Russia will now own all the oil and land that Ukraine uses to farm. It would mostly benefit Russia than the U.S
But if Ukraine gives itself up it can prevent a nuclear war between countries. Although it won't benefit the U.S, it wouldn't hurt it either. So the answer is no, it would not benefit the U.S.
The table with the data is in the picture attached.
Answer:
Explanation:
The reaction equation suggests that the law could have this form:
Then, the work is to find the values of the exponents that satisfy the initial rate data.
A first glance shows that for the third and fourth trials the initial rates are the same. Since for these two trials only the initial concentration of substance B changed (A and C were kept equal), you conclude that the reaction rate does not depend on B, and ist exponent (lower b) is 0.
Then, so far you can say:
When you use trials 1 and 2, you get:
Now, you can use trials 1 and 3 to determine the other exponent:
Thus, you have the rate law:
Now, you just use any trial to obtain k. Using trail 1:
Which yields:
