How many +I and -I atom(s) are available (Respectively)

Broadly speaking there are four types of stereisomers namely conformational isomers geometrical isomers, enantiomers and diastereomers.Although conformational isomers , have same configuration geometrical isomers have different atoms attached to each of the doubly bonded carbon atom, and enantiomers are due to chirality in the molecule Enantiomers are also known as optical isomers and diastereomers are those stereoisomers which are not enantiomers.In simple compound, number of stereoisomers.In chiral molecule is given by the reaction 2^n , where n is the number of dissimilar chiral carbon. Observe the following structures and answer the questions given below : How many stereoisomers are possible in pent-3-en-2-ol, CH_3CH=CHCHOHCH_3

A kite in the shape of a square with a diagonal 32 c m and an isosceles triangle of base 8c m\ a n d\ s i d e s\ 6c m each is to be made of three different shades as shown in Figure. How much paper of each shade has been used in it?

The reagents like AgNO_(3),K_(4)[fe(CN)_(6)],KCNS,KI,K_(2)CrO_(4) Nessler's ect, find extenstive and very important applicasion in quentitative analysis because these resgents form different type of produce with different cation for axample KI form yellow precipitate with Pb^(2+) but at form red iprecipitate with Hg^(2+) , Hence these reagents are widely used in the quantitative amalysis of morgenic salts Which of the following cation (i.e. basic radicals) forms coloured (not white) percipitates with aqueous solution of potassium iodide the precipitete does not dissolve is exiess og reagent?

An electron in an atom can be completely designated with the help of four quantum numbers. Out of these, the first three i.e., principal (n), azimuthal (l) and magnetic (m) quantum number are obtained from the solution of Shrodinger wave equation while the spin(s) quantum number arises from the spin of the electron around its axis clockwise or anticlockwise. Of these principal quantum number tells about the size, azimuthal quantum number about the shape and magnetic quantum signifies the orientation of the electron orbital. How many electrons in a given atom have the following set of quantum numbers? n = 3, l =2, m = +2, s = -1//2
