Oxygen is prepared by catalytic decomposition of potassium chlorine `(KCIO_(3))` .Decomposition of potassium , chloride gives potassium chloride (KCI) and oxygen `(O_(2))`. If 2.4 mol of oxygen is needed an experiment, how many grams of potassium chlorate must be decomposed ?

What happens when potassium dichromate is heated with sodium chloride and conc. H_2SO_4 ?

The decomposition of potassium chlorate (KClO_3) is a slow process. But the decomposition becomes fast in the presence of a black powder. Answer the following question : Can you name the substance which can slow down the decomposition of H_2O_2 ?

Oxygen gas generated by the decomposition of potassium chlorate is collected. The volume of oxygen collected at 24^(@)C and atmospheric pressure of 760 m m Hg is 128 mL . Calculate the mass ( in grams ) of oxygen gas obtained. The pressure of water vapour at 24^(@)C is 22.4 m m Hg .

A 1.0g sample of a pure organic compound cotaining chlorine is fused with Na_(2)O_(2) to convert chlorine to NaCl. The sample is then dissolved in water, and the chloride precipitated with AgNO_(3) , giving 1.96 g of AgCl. If the molecular mass of organic compound is 147, how many chlorine does each molecule contain ?

The limiting molar condcutance of sodium chloride, potassium chloride and potassium bromide are 126.45, 149.86 and 151.92 ohm^-1 cm^2 mol^-1 respectively. Calculate the limiting molar ionic conductance of Na^+ given that limiting molar ionic conductance of Br^- ion is 76.34 ohm^-1 cm^2 mol^-1 .

Chlorine is prepared in the laboratory by treating manganese dioxide (MnO_(2)) with aqueous hydrochloric acid according to the reaction 4HCl (aq) + MnO_(2)(s) rarr 2H_(2) O(l) + MnCl_(2) (aq) + Cl_(2) (g) . How many grams of HCl react with 5.0g of manganese dioxide?

Is the following name is correct ? K_3[Al(C_2O_4)_3] : potassium tris(oxalato)aluminate (III).
