Why the brass need to be immersed in the boiling water before place it in the calorimeter?
The brass needs to be immersed in the boiling water for a sufficient enough time that its temperature is the same as the boiling water, 100 degrees Celsius. That will be the initial temperature of the brass. After it is quickly placed in the calorimeter which will contain much cooler water, causing the brass to cool down and the water to heat up until the point where the temperature no longer changes. At that point the temperature of the brass is the same temperature as the water in the calorimeter, which is its final temperature of the brass.
What is Avogadros Theory?
Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. :)
What is Avogadros law?
This law give the variation in volume of a gas with amount of the gas. It states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.
Does a mixture contain molecules?
all chemical compounds contain molecules
What is the law that states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules?
Avogadro's Law

If the temperature of the air is said to be at absolute zero one might conclude?
the molecules contain a minimum amount of energy.
Does boiling water contain any gasses?
it contain gases cause of the minerals coming from the boiling water
Does a mixture contain molecules?
all chemical compounds contain molecules
Which type of molecules would have the lowest melting point?
Covalent molecules which contain only bonds between elements of similar electronegativity. For example: Carbon and hydrogen. They must not contain polar bonds like Oxygen and hydrogen.
The majority of biological molecules contain what atoms?
Organic molecules contain carbon.
What is the law that states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules?
Avogadro's Law
What are molecules and their subatomic particles?
Molecules contain atoms and these atoms contain subatomic particles.
How many atoms are found in 9 molecules of nitrogen gas?
At standard temperature and pressure, nitrogen contains two atoms per molecule. Therefore 9 molecules contain 18 atoms.
What chemical theory explains the difference in the physical property used for fractionation?
fractions with the lowest boiling points generally contain the smallest molecules, which have fewer electrons and weaker London Forces
