answer true or false
Which statements are true for two oppositely charged, isolated parallel plates: C=capacitance, U-stored energy (Q and-Q-charge on the plates). Note: Isolated plates čan not lose their charge Inserting a dielectric increases C Inserting a dielectric increases Q. when the distance is doubled, C increases Increasing the distance increases the Electric field. When the distance is halved,...

8 of 15 If the sign of a reaction rate is positive, that means The reaction does not go in the reverse direction It must be the rate for the appearance of a product. The reaction is an endothermic reaction. The reaction is an exothermic reaction. 9 of 15 Temperature increase often increases the reaction rate at least initially of...

Draw the structures of the organic products in each reaction of the
following two-step synthesis. (Hint:
The nucleophilic amine attacks the electrophilic carbonyl carbon,
and the resulting intermediate undergoes a proton shift and
dehydration. Recall what is eliminated in a dehydration process.
The second step is a reduction reaction; the reducing agent is
NaBH3CN (or H2, metal catalyst). The aromatic...
