Only a few elements from the periodic table are present in the organic compounds.
Recalling from your memory, create a list of elements present in the first and second periods of the periodic table and place them in their respective positions. Many metals and metalloids are also part of organometallic compounds. Place Na, K, Mg, Al, and Si in your periodic table.
Compound Y is obtained from a plant extract and has a sweet aroma that is similar to that of honey. Elemental composition states that compound Y contains 40.0 % carbon, 6.7 % hydrogen, and 53.3 % oxygen. Determine the empirical formula for compound Y.
During her college days, Dr. Jane Smith obtained 5000 lb of fish liver to extract pure omega-3 fatty acid, an essential nutrient. Dr. Smith burned a 4.00 mg purified omega-3 fatty acid in oxygen. Later, she determined that it had produced 11.73 mg of CO2 and 4.80 mg of H2O. Derive the empirical formula of omega-3 fatty acid.
