Compare boiling points of hydrogen peroxide with fluorine and hydrogen sulfide?
by Megara | Posted in Chemistry
How does the boiling aspect of hydrogen peroxide (H2O2) compare to the boiling points of fluorine (F2) and hydrogen sulfide (H2S), two substances with molar masses comparable with that of hydrogen peroxide?
boiling points of H2O2 , F2 and H2S
H2O2 = 150.2 °C (423.35 K)
F2 = 85.03 K (−188.12 °C, −306.62 °F)
H2S = -60.28 °C (212.87 K)
H2O2 molar legions is 34.

INDIA ADULTERATED! 70% Of Milk In Delhi, Country Is Adulterated
NEW DELH -: Take care, your daily glass of good health could actually be doing you badness. As much as 70% of milk samples picked up from the capital by a government means failed to conform to standards.
Of the 71 samples randomly enchanted from Delhi for testing by the Food Safety Standards Authority of India (FSSAI), 50 were found to be contaminated with glucose and skim withdraw powder (SMP), which is usually added to milk in the lean season to elevate volumes.
Elsewhere in the 33 states and UTs study, milk was found adulterated with soap powder, fat and even urea, besides the age-old dilution with water. Across the country, 68.4% of the samples were found contaminated.
Only in Goa and Puducherry did 100% of the samples tested adjust to to required standards. At the other end were West Bengal, Bihar, Chhattisgarh, Jharkhand, Orissa and Mizoram, where not a apart sample tested met the norms.
