Bicyclic ketone A rapidly equilibrates with a stereoisomer upon treatment with strong base, but ketone B does not. Explain why in a post with others in your group. Comment on the posts of at least two other students - have they correctly explained the difference in behavior between ketones A and B?

Asap! how do you lengthen a pattern piece? (family and consumer science, sewing)

Calculate the percent composition by mass of each element in al(oh)3. use at least three significant figures.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
