IUPAC Nomenclature for Elements with Z > 100 - All elements beyond uranium (Z=92) are synthesized in the laboratories and are known as 'trans uranium elements'. The elements, beyond fermium (Z=100) are known as 'trans fermium elements'. These elements have atomic numbers 101 onw..

The controlled combustion of fuel in the presence of air, gives an internal combustion engine its power. A low quality fuel does not burn smoothly and causes an occasional explosive sound, which is known as knocking. This greatly reduces the power of the engine. The quality of a fuel is indicated ..

; it is the result of trying to force two objects to occupy the same space. Steric interaction As the dihedral angle between the methyl groups approaches 0, the energy maximum is reached. Since the methyl groups are forced even closer together than in the gauche conformation, a large amount of ster..

15. 100 ml of 1N of an acid and 100 ml of 1N of a base are mixed at 298K. During the experiment, the temperature arose to 298.0067 K. Calculate the heat of neutralizatio..

2. A sample of helium has a volume of 520 cm 3 at 100 o C. Calculate the temperature at which the volume will become 26cm 3 . Assume that pressure is constan..

1. The solubility of iodine in water is 1.1 x 10 - 3 mol L - 1 at 288 K. 0.2 g of iodine is stirred in 100 cm 3 of water till equilibrium is reached, what will be the mass of iodine found in solution and the mass that is left undissolved. After equilibrium is reached with 0.2g of io..

14. Commercially available concentrated hydrochloric acid contains 38% HCl by mass. (a) What is the molarity of this solution? The density is 1.19 g/mL. (b) What volume of concentrated HCl is required to make 1.00 L of 0.10 M HC..

6. A gas expands from a volume of 3.0 dm 3 to 5.0 dm 3 against constant external pressure of 3.0 atm. The work of expansion is used to heat 10.0 mol of water at temperature 290.0 K. Calculate final temperature of water. (Specific heat of water = 4.184 JK - 1 g - 1..

In the E isomer above one can't determine whether they are cis or trans. The isomer is in that form because according to priority assignments, the chloro and the ethyl substituents are on opposite sides of the molecul..

Petroleum is a mixture of hydrocarbons. On combustion, it produces mainly carbon dioxide and water vapour. However, on incomplete combustion, they produce carbon monoxide, unburnt hydrocarbons etc. They also produce oxides of nitrogen. Petrol is an important fraction of petroleum used in motor veh..
