explain why silver nitrate sol. is kept in coloured reagent bottle in the lab???
What happens when dil.HCl is added to Iron Sulphide?
What happens when copper nitrate is heated in a test tube
S+HNO3 gives H2SO4 +H20 + NO2 Balance
Iron(iii)chloride is acidic while sodium carbonate is basic. Explain.
how will you separate iodine and alcohol?
what temperature would be neccessary to double the vol of a gas initially at s.t.p if the pressure is decreased by 50%
all substances cannot be changed from one state to another.give an example.
how to find the valency of radical co3(carbonate) is there any way that we can find the valency of radicals without muging up there valency
when iron is heated with sulphur,iron sulphide is formed.The total mass of iron and sulphur is equal to the mass of iron sulphide.why?
explain why sublimation is regarded as a physical change and the slaking of lime as a chemical change???
