problems involving sets.

. Note: The fast-setting tricalcium aluminate is removed to slow down the setting process. A quick setting will give rise to crystalline hydrated calcium aluminate. A slower setting yields the colloidal gel that imparts greater strength to the set m..

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..

Equilibrium Involving Chemical Systems - In reversible reactions chemical reactions take place in both the forward and backward directions. For example, the reaction between gaseous hydrogen and iodine vapours to give gaseous hydrogen iodide is a reversible reaction and may be expressed a..

In reversible reactions chemical reactions take place in both the forward and backward directions. For example, the reaction between gaseous hydrogen and iodine vapours to give gaseous hydrogen iodide is a reversible reaction and may be expressed as: In this reaction, the products cannot combine to..

Substances exist in three states: solids, liquids and gases. The following types of equilibriums exist in three states: ..
