The blood test report of a patient is given below: (RBC `5.5 million / mm^3` , Neutrophil 65% , Monocyte 5%, Basophil 1%, Eosinophile 15%, Lymphocyte 23%,Platelet `250000 million / mm^3`). Which constituent of his blood is abnormal ?

A standard solution of K_(2)Cr_(2)O_(7) (mol. Mass 294) contains 2.94 g dissolved to make 250 ml solution 20 ml of this solution with excess of 5% Kl solution liberate iodine which when titrated with Na_(2)S_(2)O_(3) solutioin using starch indicator changes blue colour to colourless just at the addition of 18 ml Na_(2)S_(2)O_(3) solution. The average oxidation number of sulphur in the product of titration and the molarity of Na_(2)S_(2)O_(3) are

A small amount of solution containing a radioactive nucleide A was administered into blood of a patient. The activity of the nucleide is 2 xx 10^(3) dps. Its half life is 15 hours. After 5 hours a sample of the blood drawn out from the patient. It's activity was 16 dpm per mL. Radioactive nuclide A^(x) decays by beta^(-) emission (42%) beta^(+) emission (58%) in the patient body Then half value of beta^(-) decay path is

A laboratory blood test is 99 % effective in detecting a certain disease when it is infact,present. However result for 0.5% of the healthy person tested (i.e.,if a healthy person is tested,then with probability 0.005, the test will imply be has the disease). If 0.1% of the population actually has the disease,what is the probability that a person has the disease given taht his test result is positive?

Which of the following statements is not true? (1) Chemically, natural rubber is a linear polymer of isoprene (2) During vulcanisation, natural rubber is heated with sulphur at a temperature range between 373 K to 415 K (3) In the manufacture of tyre rubber 5% sulphur is used as cross linking agent (4) Natural rubber is crystalline

What current would be required to deposit 1.00 m^(2) of chromium plate having a thickness of 0.052mm in 4.5h from a solution of H_(2)CrO_(4) ? The current efficiency is 74% and density of chromium is 7.19 g cm^(-3) . [Atomic mass of Cr= 52u]
