A sample of caco3 and mgco3 weighing 192 g is ignite to constant weight of 10 g. calculate sample composition.
what is the Difference between Mesomerism and Resonance
Chemical Properties Proteins - Salt formation (i) Salt formation : Due to existence of both -NH 2 and -COOH groups in proteins, they make salts along with acids and bases.
This is an acid-catalyzed addition to the double bond much like hydration, except that an alcohol rather than water is the nucleophile that reacts with the carbocation intermediate
Glucose, (C 6 H 12 O 6 ) or Aldo-hexose Glucose is termed as dextrose as it happens in nature as the optically active dextrorotatory isomer. It is as well known as grape sugar
1. Alcohols and amines are both nucleophilic. Explain why this reaction occurs to form Benadryl (diphenhydramine) 2. Outline a reasonable synthesis of the following:
Fe(atomic number = 26) atom has the electronic arrangement: (1) 2, 8, 8, 8 (2) 2, 8, 16 (3) 2, 8,14, 2 (4) 2, 8, 12, 4 Ans: 2, 8,14, 2
The maximum number of electrons which each sub-shell can occupy is: (1) 2n 2 (2) 2n (3) 2 (2l+1) (4) (2l+1) Ans: 2
