Justify the following sentence "the molality is independent from the temperature whereas molarity is dependent on temperature"

The sentence "The molality is independent from the temperature whereas molarity is dependent on temperature" is false. Molarity is also independent of temperature. When solving for the molarity, it does not require any temperature because molarity is just the moles of solute divided by liters of solvent.

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
