problems involving mass

On hydration silicates and aluminates of calcium get converted to their respective hydrated colloidal gels. At the same time, hydrolysis precipitates calcium hydroxide and aluminium hydroxide. This calcium hydroxide binds calcium silicate particles together. On the other hand, alumi..

Equivalent Mass and Number of Electrons - Equivalent mass is equal to the molecular or atomic mass divided by the number of electrons involved in the reaction per molecule, atom or ion. For example in the reaction, two electrons are needed to produce one mole..

A proton is actually a hydrogen atom, which has lost its electron. Since the mass of an electron is small, the mass of a proton is equal to the mass of a hydrogen atom. As the mass of hydrogen atom is 1 a.m.u., the relative mass of a proton is 1 a...

Mass - The SI unit is kilogram. 1 kg is defined as the mass of a platinum-iridium cylinder kept at the International Bureau of W and M at Sevres, France, established in 1887. The atomic structure of mass is yet to be develop..

Mass - Mass is the quantity of matter in the body. Mass is measured by finding out the force needed to change the way the object moves. The greater the force needed, greater the mass of the object. If you push a book, it moves faster than if you push a car wi..

Mass is the quantity of matter contained in a body. If you push a book, it moves faster than if you push a car with the same force. This is because the car has more mass than the book. If you had two identical boxes, one containing iron and the other containing cotton we could i..

The extraction of a metal from its ore involves the following step..

Processes Involved in Transport - There are some physical principles and biological processes that explain the transport of materials across the plant body. They are as follow..

Steps Involved in Photosynthesis - Photosynthesis has two main reactions: Light reaction Dark reacti..

Reactions Involving A Slow Step - If k 1 is very much less than k 2 that is k 1 << k 2 then the intermediate B is transformed into the product C as soon as it is formed. In such cas..
