Calculate the number of molecules in 500g of sodium chlorid..

It is use to fill silos (storage bins) and containers, that are used for storing food grains. After the silos are packed with the food grains, carbon dioxide is pumped into the silos from the top. The gas being heavier then air, slowly sinks down, pushing out the air in between the grains. This pr..

Borax occurs naturally as tincal (contains about 55% borax) in certain inland lakes of India, Tibet and California (U.S.A.). ..

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 calcium, potassium, sodium etc. Rainwater containing som..

The SI units of some of the physical quantities are either too small or too large. To change the order of magnitude, the metric system, which is a decimal system, relates this in powers of ten. These powers are indicated by prefixe..

: With the same number of carbon atoms, it is possible to have different arrangement of atoms and therefore entirely different compounds. With five carbon atoms, it is possible to have three isomers; with ten carbon atoms it is possible to have 75 isomers and with 60 carbon atoms over..

Rate of reaction usually doubles when the temperature is raised by ten degrees near the normal temperature because the rate constant is dependent on temperature. The temperature dependency of rate constant is mathematically expressed by the Arrhenius equation. Arrhenius equation is ..

These carbohydrates liberate two to ten monosaccharide molecules on hydrolysis. They are further classified as disaccharides, trisaccharides, tetrasaccharides, etc. based on the number of monosaccharide units. For e.g., disaccharides like sucrose produce two molecules of monosaccharides ..

'd' block elements are those in which the added electron goes into one of the 'd' orbitals. These elements have valence electrons in both their outermost and penultimate shells (second outermost) and have a general outer electronic configuration of (n - 1) d 1 - 1 0 ns 1 - 2 . The penultimat..
