Silver oxide `(Ag_2O)` decomposes at temperature `300^@C` yielding matellic silver and oxygen gas. A `1.60g` sample of impure silver oxide yields `0.104g` of oxygen gas. What is the per cent by mass of the silver oxide in the sample ?

Rate of diffucion of ozonized oxygen is 0.4sqrt5 times that of pure oxygen what is the per cent degreeof association of oxygen assuming pure O_(2) in the sample initially ?

A given sample of pure compound contains 9.81 g of Zn, 1.8xx10^(23) atoms of chromium, and 0.60 mol of oxygen atoms. What is the simplest formula?

At 0^(@)C , the density of certain oxide of a gas at 2 bar is same as that of dinitrogen at 5 bar. What is molecular mass of the oxide ?

A sample of gas occupies 1.50L at 25 o C. If the temperature is raised to 60 o C, what is the new volume of the gas if pressure remains constant?

How many grams of silver could be plated out on a serving tray by elelctolysis of a solution containing silver in +1 oxidation state for a period of 8.0 hours at a current of 8.46 amperes? What is the area of the tray if the thickness of the silver plating is 0.0025 cm? density of silver is 10.5 g/cm^3 .

The mass of N_(2)F_(4) produced by the reaction of 2.0 g of NH_(3) and 8.0 g F_(2) is 3.56 g. What is the per cent yield ?

The same quantity of electrical charge that deposited 0.583g of silver was passed through solution of gold salt and 0.355g of gold was formed. What is the oxidation state of gold in this salt?

2.0g of a sample contains mixture of SiO_2 and Fe_2O_3 . On very strong heating, it leaves a residue weighing 1.96 g . The reaction responsible for loss of mass is given below. Fe_2O_3(s)rarrFe_3o_4(s)+O_2(s) , (unbalance equation) what is the percentage by mass of SiO_2 in original sample ?

On strongs heating, One gram of the silver salt of an organic dibasic acid yields 0.5934 g of silver. If the mass percentage of carbon in it 8 times the mass percentage of hydrogen and one - half the mass percentage of oxygen, determine the molecular formula of the acid.

Weight of copper oxide obtained by treating 2.16 g metallic copper with nitric acid and subsequent ignition was 2.70 g. In another experiment, 1.15 g of copper oxide on reduction yielded 0.92 g of copper. Show that these results illustrate the law of definite proportions.
