An element X with the electronic configuration 1s 2 , 2s 2 , 2p 6 , 3s 2 , would be expected to form the chloride with the formula: (1) XCl 3 (2) Xcl 2 (3) XCl
explain law of equivalence..
Explain terminal carbons and central carbons The terminal carbons are bound to three groups, and are thus trigonal planar. The central carbon is bound to two groups, and is
Till 20elememts write the no of electrons in outermost shell.if less than 4 then this is the valency otherwise subtract from 8
Distinguish between van''t Hoff Method and Oswald Isolation Method. In each case give an expression for the rate of reaction.
1)Aniline is more basic because of the strong electron withdrawing effect of the carbonyl oxygen on the amide of acetanilide. 2)Aniline is more basic because of the strong electro
Q. What is Stoichiometry? Ans. As you know a chemical equation is like a recipe. Each of the different ingredients combine in certain ratios to form the end product. The
The uncertainty in momentum of an electron is 1 x10 -5 kg- m/s . The uncertainty in its position will be (h= 6.62 x 10 -34 kg - m 2 / s): (1) 1.05 x 10- 28 m
Stereochemical arrangement has an issue whenever an atom is bonded to two or more others. Thus triatomic substance AB2 can be bent or linear. It is observed that when a central ato
