Find the co-ordinates of each vertex of the feasible region. These co-ordinates can be obtained from the graph or by solving the equation of the line..

The two half-cell reactions are written in such a way that the reaction taking place at the left hand electrode is written as an oxidation reaction and that taking place at the right electrode is written as reduction reactio..

The first 2 electrons will go to the 1 st shell = K Shell (2n 2 ) The next shell L takes a maximum of 8 electrons (2n 2 ) In this way 2 + 8 = 10 electrons have been accommodated. The next 2 electrons go to the M Shell. K ..

Write the symbol of the ions of the compound. Cation (positive ion) is written on the left hand side and the anion (negative ion) is written on the right hand side. Put the valency number of the radical or ion below the symbol of the element. Alternatively cross the positive and negative..

Formation of chloride ion from chlorine atom in the gaseous phase. In this step energy equal to the electron affinity of chlorine is released...

We draw straight lines for the equation 2x+ y = 100 ...(2) x + y = 80 To determine two points on the straight line 2x + y = 100 Put y = 0, 2x = 100 x = 50 (50, 0) is a point on the line (2) put x = 0 in (2), y =10..

In case of inequation < or >, draw the line dotted otherwise draw the line thick. This line divides the plane into two equal part..

Purification of SO 2 from air impurities like dust, arsenic etc. are removed as otherwise these will lead to poisoning of catalys..

Let (1) be true for n = k (2..

The group of lowest priority is directed away from us and arrangement of other groups is observed. If our eye travels in a clockwise direction when moving from the group of highest priority to the group of 2 n d priority and then to the 3 r d priority group, the configuration is R. F..
