What is the bond order of N2+?
what is the law of reciprocal proportion? with examples
importance of chemistry in our daily life
a sponge can be compressed,yet it is a solid.why?
concentrated aqueous sulphuric acid is 98% H2SO4 (sulphuric acid ) by mass and has a density of 1.80gL-1 (gL raise to the power -1) . Volume of acid required to make one litre of 0.1 M H2SO4 is???
Two oxides of a metal contain 27.6% and 30% oxygen, respectively. If the formula of the first compound is M3O4, find the formula of the second compound.

(c)4/5 (d)None of these
explain MOLARITY, MOLALITY and NORMALITY in DETAIL.?
what is the relation between mole fraction and molality?
please can anyone explain it in a simple way....
