You needn't fret over the elemental properties of the periodic table anymore. Here, you can effortlessly access chemical reactions and reaction principles corresponding to each element. Deductive reasoning from microscopic phenomena to discern the original structure of molecules and atoms is a research technique we staunchly champion.

. Who is known as the "Father of The Periodic Table"?

(3) (ii) 1 g of nitrogen has a volume of 0.86 litres at room temperature and pressure. What volume of nitrogen would be produced from 130 g of sodium azide? (If you did not answer part (a)(i) assume that the mass of nitrogen produced from 130 g of sodium azide is 80 g. This is not the correct answer to part (a) (i).) __ Volume=litres

Atomic weight is A a weighted average of the masses of isotopes of an element based on abundance. B determined by weighting individual atoms. C an average weight of the isotopes of an element. D the number of protons and neutrons in a nucleus.

A propane tank containing 55L has 2.46 moles of the gas . ( C_(3)H_(8) is propane What would be the of moles if 1/2 of the gas is used?

) A flask that weighs 435.8 g is filled with 235 mL.of carbon tetrachloride. The weight of the flask and carbon tetrachloride is found to be 703,55 g. From this information , calculate the density of carbon tetrachloride. (Hint: You first have to find the mass of just the carbon tetrachloride)
