Bromine particles are almost twice as heavy as chlorine particles. Which gas will diffuse faster , bromine (vapour) or chlorine ? Explain your answer.

Text Solution

Verified by Experts

The correct Answer is:
Chlorine will diffuse faster than bromine vapour. This is because light molecules diffuse faster than heavy molecules

A particle with positive charge Q is held fixed at the origen. A second particle with positive charge q is fired at the first paricle, which follows the trajectory as shown in fig.

(b) Does the Coulomb force that one charge exerts on other charges changes if the other charges are brought nearby?(yes/No)

There is a fixed sphere of radius R having positive charge Q uniformly spread in its volume. A small particle having mass m and negative charge (– q) moves with speed V when it is far away from the sphere. The impact parameter (i.e., distance between the centre of the sphere and line of initial velocity of the particle) is b. As the particle passes by the sphere, its path gets deflected due to electrostatics interaction with the sphere. (a) Assuming that the charge on the particle does not cause any effect on distribution of charge on the sphere, calculate the minimum impact parameter b0 that allows the particle to miss the sphere. Write the value of b_(0) in term of R for the case 1/2mV^(2)=100.((kQq)/(R)) (b) Now assume that the positively charged sphere moves with speed V through a space which is filled with small particles of mass m and charge – q. The small particles are at rest and their number density is n [i.e., number of particles per unit volume of space is n]. The particles hit the sphere and stick to it. Calculate the rate at which the sphere starts losing its positive charge (dQ)/(dt). Express your answer in terms of b_(0)

A sodium salt (A) is heated with cone. Sulphuric acid. The evolved gas truns moist litmus paper red and producess white fumes in contact with a glass rod moistened with ammonia solution. It also gives white precipitate when passed through AgNO_(3) solution. When the salt is heated with MnO_(2) and cone.

Explain your answer with relevant chemical equations.

The oxides of Cl, Br and I are well known. They have various composition. The oxides are thermally unstable and dangerously explosive. They react with alkali. The bromine oxides are thermally more stable than chlorine oxides. The structure of halogen oxides is explained on the basis of VSEPR theory. The hydrides of chlorine, bromine and iodine can be made by direct synthesis an they are well strongly fuming become increasingly more powerful reducing agents. Halogens also form oxoacids of the form HOX,HXO_(2) ,HXO_(3) " and " HXO_(4) The acidic character of oxoacids and halogen oxides decreases from 'Cl' to 'I', however it increases with increase in oxidation number of halogen in them. Which of the following does not dimerise?
