If lecithin still had all its ester linkages would you get a positive acrolein test?
Yes, if lecithin still had all its ester linkages intact, it would not give a positive acrolein test. Acrolein test detects the presence of unsaturated carbon-carbon double bonds, which would be available only if ester linkages are broken, releasing the fatty acids from lecithin.
How can a soda be a physical change?
A soda can undergo physical changes such as temperature changes causing condensation on the can, or changes in pressure leading to fizziness. These changes do not alter the chemical composition of the soda itself, making them physical changes.
Why changes of stat are physical changes?
Changes in state are physical changes because they involve a change in the physical appearance or state of a substance without altering its chemical composition. For example, when water changes from a liquid to a solid (freezing) or a gas (vaporization), it is still water chemically. This contrasts with chemical changes, which involve a rearrangement of atoms and result in the formation of new substances.
