Short Answer TypeExplain how you can determine the atomic mass of an unknown metal if you know its mass density and the dimensions of a unit cell of its crystal.
Differentiate between molarity and molality values for a solution. What is the effect of change in temperature on molarity and molality values?
Molarity is defined as the number of moles of solute dissolved per litre of solution.
Molality of a solution is defined as the number of moles of solute dissolved in 1000 grams of solvent.
The thermal decomposition of HCO2H is a first-order reaction with a rate constant of 2.4 x 10-3 s-1 at a certain temperature. Calculate how long will it take for three-fourths of the initial quantity of HCO2H to decompose.
(log 0.25 = - 0.6021)
What do you understand by the rate law and rate constant of a reaction?
Identify the order of a reaction if the units of its rate constant are:
(i) L-1 mol s-1
(ii) L mol-1 s-1Describe the principle controlling each of the following processes:
(i) Preparation of cast iron form pig iron.
(ii) Preparation of pure alumina (Al2O3) from bauxite ore.
