Stoichiometric Calculations Involving Reactions/Solutions - Most chemical reactions are carried out in solutions. It is therefore important to know how to express the concentration of the substance in its solution. Most common ways of expressing concentration of any solute in a ..

The molar volume [22.4L at STP] plays a vital role in stoichiometric calculations because it is the link between volume and mass in reactions involving gase..

One mole of any gas at STP will have a volume of 22.4 L. This is called molar volume. The molar volume [22.4 L at STP] plays a vital role in stoichiometric calculations because it is the link between volume and mass in reactions involving gas..

1. Calcium hydroxide is used in the preparation of lime water. Lime water is a saturated solution of calcium hydroxide in water. 2. It is used to make milk of lime for white washing. When a small quantity of water is mixed with slaked lime, milk of lime paste is formed. It is used for white washi..

The above results can be summarized as follows: When a reaction proceeds, the number of moles converting from reactants to the products may or may not change. The change in the number of moles (except for pure liquids, solids and solvent in excess) converting from reactants to the products is calle..

The natural 'Green-house Effect' is essential for life on earth. Various gases in the atmosphere like water vapour and carbon dioxide trap some of the outgoing radiation from the earth, retain the heat and keep the earth's temperature at levels where living things, including man, can survive. How..

E.g., Water gas and producer gas from coke, coal gas from coal, Bio gas from animal dung, coke from coal, petrol, kerosine, diesel and furnace oil from petroleum, charcoal from wood Moreover different fuels give different amounts of heat on burning. The heat liberated in joules ..

>In a hydro power plant electricity is produced from water. Hydro power plants convert the potential energy of falling water into electricity. Wind Energy Moving air is called wind Wind possesses kinetic energy Wind energy can be used to sail boats, grind grains, pump water and generate electricity..

Submarine - The submarine is another application of 'Archimedes Principle'. On surface, the submarine floats, with its conning tower and most of the deck, being clear of the wate..
