Calculate the rate of reactant between two interval. eg- the ΔR1 between 0 to 50 seconds is 1.90 and ΔR2 Between 50 to 100 is 1.70. Here rate of reactant(C4H9Cl) is decrease with time.

There are two cases if galvanic cell is dead: 1- if the less amount of CuSo4 in solution. Some time later Cu++(aqua) is not convert copper rod. 2- In this cell after some time the whole Zn electrode convert into Zn++(aqua). so the current is not flow and galvanic cell is dead.

1. In VBT Ligands have atleast one lone pair. 2.The central metal atom makes available the number of empty orbitals for the formation of coordinate bonds. 3. Coordination bond is formed when ligand donate lone pair od electron to the central metal atom. 4. The d- orbital involve hybridization may be either inner (n-1)d or outer(nd). 5.Octahedral ,square planner and tetrahedral complexes are formed as a result of (d²sp³/sp³d²),dsp² and sp³ hybridization respectively of the central metal atom.

In aniline, the N is high electron withdrawing group. Due to this they tightly held H in benzene. So it is not show friendal craft reaction

Because in friedl craft reaction Luis acid is used which is anhy agcl3 and aniline is basic in nature when they react they form salt but not water because of absence of H2

Polonium is a very rare, radioactive metal. There are 33 different isotopes of the element and all of the isotopes are radioactive. It exists in a variety of states, and has two metallic allotropes. It dissolves easily into dilute acids. Polonium does not exist in nature in compounds, but it can form synthetic compounds in the laboratory. It is used as an alloy with beryllium to act as a neutron source for nuclear weapons. Polonium is a highly toxic element. The radiation it emits makes it very dangerous to handle. It can be immediately lethal when applied at the correct dosage, or cause cancer if chronic exposure to the radiation occurs. So look them u can easily find difference b/w them okkkkk.......

Tellurium Tellurium is the metalloid of the oxygen family, with a silvery white color and a metallic luster similar to that of tin at room temperature. Like selenium, it is also displays photoconductivity. Tellurium is an extremely rare element, and is most commonly found as a telluride of gold. It is often used in metallurgy in combination with copper, lead, and iron. In addition, it is used in solar panels and memory chips for computers. It is not toxic or carcinogenic; however, when humans are exposed to too much of it they develop a garlic-like smell on their breaths.
