The use of vermilion on rubric of the Tartar Relation is confirmed by the presence of three lines attributed to HgS. Why should this diatomic have more than one vibrational line?
WHAT IS THE SYLLABUS OO GROUP -I?
Normally entropy is expressed as q/T. But, work and heat have same unit. Why can't it be replaced by work?

During Soundness testing of Cement by Lechatelier method the Cement mould expands about 20 mm when merged in curing water for 24 hours after mould preparation.In that Cement MgO content is about 3.0%,SO3 is about 2.6% & Blaine is about 360 M2/Kg.Guess the reason & suggest solution.
In testing of Cement the formula for water requirement for setting time is as below- Water required for setting time = NC x 0.85 The question is that what is the logic of 0.85 in this formula??
what is the difference between elctrefining and electrolysis?
Sr-90, a radioactive isotope, is a major product of an atomic bomb explosion. It has a half life of 28.1 year. Calculate the first order rate constant for this nuclear decay and the fraction of 90Sr that remains after 10 half lives?
The rate constant for the second order reaction is 0.54/M.s at 300oC. How long (in sec) would it take for the concentration of NO2 to decrease from 0.62M to 0.28 M? 2NO2(g) 2 NO(g) + O2(g)
