State the law of Dulong and Petit's and explain how far it is of
use in the determination of atomic weight. The chloride of a
metal is found to contain 20.2% of the metal. The specific
heat of the metal is 0.224. The vapour density of its chloride is
133.4. Calculate the exact atomic weight of the metal and also
write down the molecular formula of its chloride.

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.

Hey guys so i need to know what is _nh3+> nh4oh ~chemistry~

Using the first volume and temperature reading on the table as v1 and t1, solve for the unknown values in the table below. remember to use the rules of significant figures when entering your numeric response.
