CnH2n since the equivalent unsaturation is equal with 1
Answer:
b. In equilibrium with the liquid phase, the pressure exerted by a gas.
Explanation:
When a liquid is warmed up to a temperature , it starts vaporising . The liquid is turning into gas and gas is turning into liquid at different rates . Initially the rate of former is higher but gradually the difference of rate between them decreases to zero . At this point the rate of conversion of liquid into gas and rate of conversion of gas into liquid becomes equal . This is called dynamic equilibrium point .
If we change the temperature , the equilibrium gets disturbed .
At this point the pressure exerted by the gas is called the vapour pressure of the liquid .
So option b ) is correct .
The answer to this questions is letterB
The main function of the right side of your heart is to collect blood from the body and pump it to the lungs.
Hey there !
Mole ratio :
<span>2 KMnO4 + 16 HCl → 2 KCl + 2 MnCl2 + 8 H2O + 5 Cl2
2 moles KMnO4 ----------------- 8 moles H2O
3.45 moles KMnO4 ------------- (moles H2O )
Moles H2O = 3.45 * 8 / 2
Moles H2O = 27.6 / 2
= 13.8 moles of H2O
</span>The option that was given is wrong , <span>You're right.</span>
