Answer:
Explanation:
In the attached picture you may find the structure of betaxolol.
You can see the alcohol group C-O-H as well as the ether group C-O-C.
The arene -or aromatic ring- can also be seen.
There's also a secondary amine group, C-NH-C.
Answer:
The frequencies of the two lines are:
a)
b)
When we heat rubidium compound we will see red color.
Explanation:
c = speed of light
= wavelength of light
a) Frequency of the light when wavelength is equal to
This frequency corresponds to red light
b) Frequency of the light when wavelength is equal to
This frequency corresponds to violet light
When we heat rubidium compound we will see red color.
Answer:
Explanation: The given chemical reaction is:
Equilibrium constant (Kc) in general is written as:
Note:- Coefficients are written as their powers
So, the Kc expression for the above reaction will be:
Equilibrium moles are given for all of them. Let's divide the moles by given liters to get the concentrations.
= 0.040 M
= 0.0658 M
= 0.0217 M
Plug in the values in the equilibrium expression to calculate Kc.
