Which of the following is not true in Rutherford's nuclear model of atom:
(1) Protons and neutrons are present inside nucleus
(2) Volume of nucleus is very small as compared to volume of atom
(3) The number of protons and neutrons are always equal
(4) The number of electrons and protons are always equal
Ans: The number of protons and neutrons are always equal
Explain The compound decarboxylates The compound decarboxylates; it is a disubstituted malonic acid in which the two a substituents are connected within a ring. The net effect
1) A 100 mL 0.4M acetic acid soln is titrated with 0.5M NaOH. Write a reaction equation to work the following: a) What volume of the base would be required to reach the equivalenc
A compound exists in 2 forms. One them produces 2moles of AgBr while the other produces 1mole of AgBr with AgNO3
The energy required to dislodge electron from excited isolated H-atom, IE 1 = 13.6 eV is: (1) = 13.6eV (2) > 13.6eV (3) 3.4 eV
Q. Determine Molecular Mass of Atoms Ans: 6.02 x 10 23 is a really big number. It would be hard to count that many of any object. That's one of the reasons we count atoms b
For the following cyclohexane molecule, illustrate clear representations of both possible chair forms of the molecule. Be sure to properly draw all the axial and equatorial groups
Delocalisation of electrons in conjugated system is called resonance. For example there is delocalisation of electrons in benzene ,hence we write kekule structure for benzen.
The transition metal complexes are known to be paramagnetic in character. CFT helps us to understand the magnetic properties in terms of magnetic susceptibility measurements. The m
