Answer:
b. The pressure in the container will be 100mm Hg.
d. Some of vapor initially present will condense.
Explanation:
The vapor pressure of liquid Pantene rises when there is container where evacuation of water molecules is restricted. The pressure inside the container rises to 100 mm Hg and then liquid molecules start condensing. These molecule form vapors.

<h3>What is the colour of lemon in white light?</h3>
A lemon in white light appears yellow to the human eye because yellow light is reflected by the lemon's surface while all other wavelengths of light are absorbed.
If the same lemon is placed into red light. It will appear to look red. This occurs because the red light will be transmitted by the lemon's surface and red light will be reflected to your eye.
So we can conclude that we see that colour which is reflected by the surface because the object is made up of that colour.

Answer:
1.125moles
Explanation:
mass of NaOH,m= 45g
molar mass of NaOH, M= 23+16+1
= 40g/mol
mole,n =m/M
n= 45/40
n=1.125mole
