the solutions of the quadratic equation as the solutions.

For two different, real solutions ( z 1 and a 2 ) of a quadratic equation, find the condition for the sum and product of these solutions to be equal. => a 2 = z 1 /( z 1 - 1) or a 2 = z 1 or a 2 = z 1 /( z 1 + 1) or a 2 = 1..

Choose a quadratic equation that has the solutions 13 and 9. => x 2 - 22 x + 4 = 0 or x 2 - 4 x + 117 = 0 or x 2 - 22 x + 117 = 0 or x 2 + 22 x + 117 = 0..

Solutions - Solution is defined as a homogeneous mixture of two or more chemical substances. The state of matter of a solution may be solid, liquid or gaseous. For example, common salt in water (liquid solution), air (gaseous solution), alloys (soli..

The given skeleton equation can be split into two partial equations. Partial eq.1 Partial eq.2 The two partial equations are balanced by hit and trial method. Balanced partial eq.1 Balanced partial eq.2 NaClO does not ap..

is a homogeneous mixture of a solute dissolved in a solvent. Examples: Salt and water, sugar and water, iodine and alcohol. It should be remembered that: 1. A Solution is a homogeneous mixture of two or more substances. These substances can be in any of the three physical stat..

A Solution is a homogeneous mixture of two or more chemically non-reacting substances called components. The composition of the components can be varied with in certain limit..

(a) 38% solution, means 38 g of HCl in 100 g of solution. Then, Mass of the solution= 100 g Molar mass of HCl = 36.5 g mol - 1 (b) The molarity of conc. HCl sample = 12.38 mol/L Molarity of HCl solution to be prepared = 0.10 mol/L Volume of HCl ..

2 M solution of H 2 O 2 means 2 mol of H 2 O 2 in one litre of the solution. Molar mass of H 2 O 2 = (2x1 + 2x16) g/mol =(2 + 32) g/mol = 34 g/mol Thus, there are 68 g (= 2 x 34 g) of H 2 O 2 in one litre of the solution. So, Mass of H 2 O 2 in 100 mL of sol..
