Assuming aluminium (At mass = 27) has a density of 2.7 g cm - 3 and its unit cell has an edge of 400 pm, what is the nature of the crystal lattice for the meta..

56 ml of carbon dioxide has a mass at 0.11 g at STP. What is the molar mass of the carbon dioxi..

This is a representative list of topics covered in our Grade 10 Chemistry program - however all programs will be customized for the individual student...

Chemistry of Salt Formation in Seawater - The chemistry of seawater is very complex. Many multistep equilibrium operate simultaneously. A sequence of chemical reactions following the weathering of the igneous rock is given below: Igneous rocks consist of aluminosilicates of calc..

>Catalysis involves reactions where catalysts are used. Catalysts are used to accelerate the rate of reaction. Catalysts accelerate the rate of reaction by providing an alternate reaction pathway in which the activation energy is lower. Homogenous catalysis involves catalysts which are of the same ..

Metals such as silver, gold and platinum adsorb oxygen gas at 500 o C. Molten silver absorbs ten times its mass of oxygen and expels it rapidly on cooling. This phenomenon is called the spitting of silve..

Transparent crystalline solid with ten molecules of water per molecule Soluble in water Washing soda solution is alkaline due to hydrolysis Has detergent or cleansing properties Less corrosive Efflorescen..

These consist of all 's' and 'p' block elements excluding the noble gases (group 18 elements). The chemical properties of the representative elements are determined by the number of valence electrons in their atoms. The number of valence electrons belonging to the above two blocks are: 's' block el..

Representative or Main Group Elements - These consist of all 's' and 'p' block elements excluding the noble gases (group 18 elements). The chemical properties of the representative elements are determined by the number of valence electrons in their atoms. The number of valence electrons belonging t..
