Both lithium and sodium combine directly with hydrogen, sulphur, halogens and other non-metals on heatin..

A basic buffer contains a weak base (BOH), and its salt with strong acid (BX). The buffer solution thus contains large amounts of the weak base BOH, and the cation B + (coming from the dissociation of the salt BX), in addition to H 3 O + and OH - . The addition of an acid or a base to the basic ..

W = FS cos q If the displacement S is in the direction of the force F, q = 0, cos q =1 Then, W = FS x 1 W = FS If q = 90 o , cos 90 o = 0 Therefore, W = FS x 0 = 0 i.e, no work is done by the force on the body. If a stone tied at the end of a string is whirled around in a circle..

Law of Mass Action and Equilibrium Constant - The law of mass action correlates the rate of a chemical reaction and the concentration of the reactants. C.M. Guldberg and P. Waage (1864-67) suggested this relationship. This law states that, at a constant temperature and pressure,..

. In the first experiment, when two spring balances are pulled in opposite directions, they experience the same force acting in the opposite directions. In case of the balloon when you release it, the air inside the balloon rushes out downward, exerting force on the air outside...

Erosion of soil can be due to action of water or air. Erosion of soil by water can be prevented by a) Checking of overgrazing and stopping the cutting down of forests. b) Terracing of sloping lands reduces the speed of water and prevents soil erosion. c) Bunds around the fields checks th..

Causes of Pollution - The ultimate cause of pollution is human activity itself. Pollution is a human contribution to nature. Science has evolved technologies and technologies have helped the human welfare. In the process, the pollution has been a part of technology and therefore a part of human mis..

(action force) and the board in turn pushes the man forward in the opposite direction (reaction force) The birds, while flying, push the air downwards with the help of their wings (action force) and the air in turn exerts a force on the bird in the upward directio..

Inertia is the inability of material body to change, by itself, its state of rest or of uniform motion in a straight line. Mass is a measure of inertia Newton's first law of motion: A body continues in its state of rest or of uniform motion along a straight line unless an external unbalance..

The human circulatory system is a closed circulatory system. The blood flows in closed vessels without coming in direct contact with the cells of the body. The walls of the blood vessels are made up of three layers: Inner endothelium - single layer of cells Tunica media - made of smooth i..
