Main Answer: The resultant solution will have 0.125M of HCl.
Explanation:
Given:
Volume of NH3 V1= 25ml = 0.025lit
Molar concentration of NH3 M1= 0.1M
It is titrated with HCl
Molar concentration of HCl M2= 0.25M
Volume of HCl V2= ?ml
At equilibrium,
M1V1 = M2V2
V2 = M1V1/M2
V2 = (0.1*0.025)/0.25
V2= 0.01lit =0.01*1000 = 10ml
Number of moles = M2*V2 = 0.25 * 0.01 = 0.0025
Now 10ml of HCl is added.
then,
V2 = 10 + 10 = 20ml
Molar concentration of HCl = number of moles/Volume
= 0.0025/0.02
= 0.125M
The resultant solution will have 0.125M of HCl.

It was concluded that different liquids do evaporate at different rates, according to the physical properties of the given substance. Nail polish remover vaporized the quickest, followed by water, salt water, vinegar, orange juice and oil.
From the absorption spectra of a gas, we can see the amount of thermal energy the gas contains (option D).
<h3>What is the absorption spectra?</h3>
The absorption spectra shows us the energy that is taken in by a gas. We know that when a gas is heated, it absorbs energy which shows up in its absorption spectra.
Thus, from the absorption spectra of a gas, we can see the amount of thermal energy the gas contains.
