properties of determinant

If the rows and columns of a determinant are inter-changed, the value remains unaltered. If any two rows (columns) of a determinant are identical, its value of the determinant is zero. If any two rows (columns) of a determinant are interchanged, the v..

Determine whether the associative property satisfied under the division operation. => No or Yes..

Determine whether the set {0, 7, - 7} satisfies closure property with respective to multiplication. => Yes or No..

When the elements are arranged in the order of increasing atomic numbers there is a recurrence of similar properties after certain regular intervals. This regularity is called the periodicity in properties. The distribution of electrons in the various shells determines..

Properties of Matter - A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually crystallin..

Colloidal particles have high average molecular masses. Therefore the mole fraction of the dispersed phase is very low. Hence, in colloidal solutions the relative lowering of vapor pressure, elevation in boiling point, depression in freezing point and osmotic pressure is very low. However, osmotic..

The rate of a reaction is determined by measuring the concentration of the reactant or product at different intervals of time. The concentration is measured, by measuring a related property such as color, pressure or volume (as in the case of gas phase reactions), pH, optical ro..

Experimental Determination of Rate of Reaction - The rate of a reaction is determined by measuring the concentration of the reactant or product at different intervals of time. The concentration is measured, by measuring a related property such as color, pressure or vol..

The excess pressure that must be applied to the solution/conc.solution to prevent osmosis. fig 3.11 - Principle of measuring osmotic pressure fig 3.12 If two solutions of identical composition but different concentration are separated by a semi permeable membr..

The density of a substance remains the same under certain specified conditions. Thus the density of a substance is one of its characteristic properties and this property can be used to determine the purity of any substanc..
