All acids contain hydrogen. Binary acids contain only two elements one of which is hydrogen. They are named as Hydro, and then the name of the non-metal with the suffix - ic is added. Remember : HCl - Hydrochloric acid HBr - Hydrobromic acid Hl - Hydroiodic aci..

Binary compounds are compounds containing only two elements. If one of the two is a metal (or ammonium), then the suffix - ide , is added to the non-metal atom. Remember : NaCl - Sodium chloride CaO - Calcium oxide AlN - Aluminium nitride If atoms of two elements form more than..

They contain more than 2 kinds of atoms. The term 'hydro' is not used. Instead, the name is based on the second element in the formula. Remember : H 2 SO 4 - Sulphuric acid If the same elements form two acids, then the one containing greater number of oxygen atoms gets the suffix - ic a..

Equality of Matrices - Two matrices are said to be equal if they have the same order and their corresponding elements are equal. e.g., then a = 1, b = 2, c = 3, d = 4, e = 5 and f = ..

Let us refer to a circuit consisting of two switches p and q connected in series with a lamp and battery as shown in figure. The lamp will glow, only if switch p and switch q are closed. If we replace the word 'closed' by T and 'open' by F, the switch will glow only if p = T and q = T. In b..

A manufacturer makes two models A and B of a product ,each should be processed by two machines. To complete one unit of model A, machines I and II must work 1 hour and 2 hours respectively. To complete one unit of model B, Machine I and II must work 4 hours and 2 hours respectiv..
