From the figure we can notice that the tip is ended surely before 9 cm .
Also , the tip crossed two cuts after 8 .
Therefore , it is greater than 8.2 .
Now , if we see that the tip end between 2 and 3 .
Therefore , the best estimate is 8.25 cm .
Hence , this is the required solution .
It’s B the cu looses its 2 and passes it to the NH3 that needs a bracket to separate them. The NH3 doesn’t loose its 3 because it’s already a compound!
Hope this helps!
Answer:
The effects of each kind of radiation is different on the molecules.
Explanation:
Microwave causes molecules that have two opposing poles to spin rapidly due to absorption of the electromagnetic radiation waves. When molecules absorb Infrared radiation, changes occur from a ground vibrational state to an excited vibrational state. When the visible light is absorbed by molecule, the electron is excited and goes to an orbital of higher energy than the lower energy. Ultraviolet radiation turns the stable molecule into a reactive species.
Answer:
The rate will increase by a factor of 5.00 too.
Explanation:
Hello,
In this case, given the rate law:
Thus, we can notice it is first-order respect to A, for that reason, increasing its concentration by a factor of 5.00, increase the rate by a factor of 5.00 as well.
Moreover, if the concentration of B is increased by the same factor, the rate will increase by a factor of 25.00, since the rate is second-order respect to B (it is squared).
Best regards.
Since HCl is a strong acid, it readily dissociates, so we can assume that there are 1.0x10^-3 M of H+ ions. We can use the formula:
pH=-log[H+]
pH=-log(1.0x10^-3)
pH=3
We can find the pOH by subtracting 14-pH:
14-3=11
pOH=11
The [OH-] can be found by using the formula:
pOH=-log[OH-]
11=-log[OH-]
10^-11=[OH-]
[OH-]=1.0x10^-10
