Experiment because she is actually taking the samples and testing them.
Answer:
Answer
Correct option is
A
9
pK
b
=−logK
b
=−log10
−5
=5
A mixture of ammonium hydroxide and ammonium chloride forms basic buffer solution.
The Hendrson's equation for he basic buffer solution is as given below.
pOH=pK
b
+log
[acid]
[salt]
Substitute values in the above expression.
pOH=5+log
0.1
0.1
=5
Hence, the pH of the solution is pH=14−pOH=14−5=9

Different wavelength are involved.
Explanation:
If magnesium burns with a bright white flame, one can conclude that different wavelengths accompany the electron transitions for the magnesium atom.
- When an atom burns, the electrons in it are excited.
- They give out characteristic light commensurate with their energy.
- A white light is made up of different combinations of wavelength of radiations.
- When we see a white light we can infer that different joined together in the emission observed.

Answer:
is the maximum velocity of this reaction.
Explanation:
Michaelis–Menten 's equation:
v = rate of formation of products =
[S] = Concatenation of substrate
= Michaelis constant
= Maximum rate achieved
= Catalytic rate of the system
= Initial concentration of enzyme
We have :
is the maximum velocity of this reaction.
