Answer:
The initial concentration is 
Explanation:
From the question we are told that
The volume of solution A is 
The concentration of A is 
The volume of solution B is 
The volume of water is 
Generally the law of dilution is mathematically represented as
Where 
is the concentration of the mixture
is the volume of the mixture which is mathematically evaluated as
So
substituting values
Note the mixture obtained is 
Explanation:
A gas has a temperature of 273.15 K and a pressure of 101.325 kPa. It can be concluded that this gas has reached standard temperature and pressure.
Standard temperature is zero degree celcius which corresponds to 273.15 degree kelvin.
Standard pressure is 760 mmHg which corresponds to 101.325 kPa.

Answer:
extensive hydrogen bonding
Explanation:
The high boiling points of water, hydrogen fluoride (HF) and ammonia (NH3) is an effect of the extensive hydrogen bonding between the molecules. The London dispersion force is caused by random and temporary changes in the polarity of atoms, caused by the location of the electrons in the atoms' orbitals.
