Calculate the mass of H2SO4 present in 250 cubic centimetres of semi normal solution

CBSE > Class 12 > Chemistry

1 answers

Palak Gulati 4 years, 10 months ago

Given: volume of solution = 250cm³ = 0.25 litres seminormal solution means normality = 1/2 Solution: we know that, normality= mass of solute/volume of solution in litres therefore, N = mass/ volume(L) 1/2 = mass/0.25 mass = 0.25/2 mass = 0.125g

ANSWER

10 g of sucrose are dissolved in1000g of water. Find mass% of sucrose in solution

What is the anamolus behaviour of nitrogen.

Posted by Nitin Dudy 8 years ago

CBSE > Class 12 > Chemistry

3 answers

Tanuja Biswas 8 years ago

Anamolous behavior means a behavior which is different from the expected trend. Nitrogen, the first element in the group 15. Shows different properties from that of other fellow elements. It does not has d orbital thus it cannot extend its covalence to show +5 oxidation state like phosphorus and other elemnts can. Nitrogen exists as dinitrogen ....gaseous form at room temperature. Its forms triple bonds and unlike others has a very high bond dissociation enthalpy....there are many other anomalies in behavior of nitrogen... Even in all the first elemnts of each group in s n p block ...main reason is small size and absence of d orbital.
