Question

0.8 g mixture of NaCl and NaNO3 was dissolved in water and treated with excess of AgNO3

solution. The precipitate formed was filtered, dried, and weighed. If the mass of the

precipitate was found to be 1.435g. Calculate the composition percentage of the mixture.​

Answer 1

Answer:

It was initially believed that the noble gases could not form compounds due to their full valence shell of electrons that rendered them very chemically stable and unreactive. All noble gases have full s and p outer electron shells (except helium, which has no p sublevel), and so do not form chemical compounds easil by
