Stearic acid [CH_(3)(CH_(2))_(16)CO_(2)H] is a fatty acid the part of fat that stores most of the energy .1.0 g of Stearic acid was burnt in a bomb calorimeter . The bomb had capacity of 652 J//^(@)C . If the temperature of 500 g water rose from 25.0 to 39.3^(@)C how much heat is released when the stearic acid was burned? ["Given "C_(p)(H_(2)O)=4.18J//g^(@)c]
In order to determine the volume of blood in an animal, a 1.0 mL sample of solution of 10^(3) dpm of ._(1)^(3)H is injected into the animal blood stream. After sufficient time for circulatory equilibrium to be established, 2mL of blood is found to have activity to 10 dpm. The volume of blood in animal is : a) 199 mL b) 198 mL c) 200 mL d) 20 mL
A small quantity of solution containing Na^24 radio nuclide (half-life=15 h) of activity 1.0 microcurie is injected into the blood of a person. A sample of the blood of volume 1cm^3 taken after 5h shows an activity of 296 disintegrations per minute. Determine the total volume of the blood in the body of the person. Assume that the radioactive solution mixes uniformly in the blood of person. ( 1 curie =3.7 xx 10^10 disintegrations per second)
The percentage by volume of C_(3)H_(8) in a gaseous mixture of C_(3)H_(8),CH_(4) and CO is 20. When 100mL of the mixture is burnt in excess of O_(2) the volume of CO_(2) produced is :
Categorize the following compound as strong and weak acid and base: H_2CO_3
A 3.4g sample of H_(2)O_(2) solution containing x%H_(2)O by mass requires xmL of a KMnO_(4) solution for complete oxidation under acidic conditions. The normality of KMnO_(4) solution is :
