The experiment was done as per procedure described above and the results are (a) Filter paper after painted with rose extract
(b) Filter paper after painted with rose extract followed by re-painting with acidic and basic solutions
1) Explain the chemical principles underlying the creation of your art. Use equations and structures. In other words explain why the vase is blue, the petals pink and some petals are light yellow , and other parts of the picture are deep yellow
2) Write mechanisms (using curved arrows) for the reaction (deprotonation of an alcohol by a base) for compound 1 converting to compound 2 as outlined in Scheme 1 3) Write mechanisms (using curved arrows) for the reaction (deprotonation of an alcohol by a base) for compound 2 converting to compound 3 as outlined in Scheme 1

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
