9. Calculate the time in seconds for the decomposition of
nitrogen pentoxide which follows first order kinetics when
concentration of N2O5 is dropped from 0.1 to 0.01M
(k=6.22x1045)
10. Explain Swartz reaction with example.
11. How is cast iron different from pig iron? How is pig iron
converted into cast iron?​

Answer 1

Explanation:

10) Swarts' reaction is generally used to get alkyl fluorides from alkyl chlorides or alkyl bromides. This is done by heating of the alkyl chloride/bromide in the presence of the fluoride of some heavy metals (silver fluoride or mercurous fluoride for example).

11)CAST IRON IS MADE FROM PIG IRON BY MELTING PIG IRON WITH IRON SCRAP AND COKE AND BY PASSING HOT AIT BLAST INTO THE MIXTURE. CAST IRON HAS 3% CARBON CONTENT LOWER THAN PIG IRON. CAST IRON IS HARD AND BRITTLE .

i know These two only Hope it helping you
