Answer:
number of moles = 0.1001 mol
Explanation:
number of moles = mass/molar mass
number of moles = 3.65g / 36.459 g/mol
n = 0.1001 mol
I don’t know not really sure just need the point sorry
Answer:
Explanation:
Hello there!
In this case, since the chemical equation representing the neutralization of the weak base quinine can be written as follows:
Whereas we have 0.100 moles of the base and those of acid as shown below
Which means that the remaining moles of quinine are:
And the resulting concentration:
Now, the calculation of the pH requires the pKb of quinine (5.1) as its ionization in water produces OH- ions:
And the equilibrium expression is:
Which is solved for x as follows:
Which means the pOH is:
And the pH:

Answer: longer wavelength and lower energy.
Explanation:
1) The wavelength is inversely related to the frequency. So, an electromagnetic wave with lower frequency will have longer wavelength.
This is the formula for electromagnetic waves:
λ = c / ν
where λ is the wavelength, c is the speed of light, and ν is the frequency.
2) Energy is directly related to the frequency.
This is the formula E = hν,
where E is the energy, h is Planck constant, and ν is the frequency.
So, the lower the frequency the lower the energy.
3) Conclusion:
<span>An electromagnetic wave that has a lower frequency than infrared radiation will have longer wavelength and lower energy than the infrared radiation</span>
I believe the atomic level increases hope this helps.
