The -NH, group is listed in our textbook as the strongest o,p-directing activator in electrophilic aromatic substitution reactions. However, when aniline is subjected to standard nitration conditions poor yields of m-nitroaniline result. Draw all the resonance forms of aniline showing the electron-donating effect of the -NH, a. substituent. b. Clearly, the reaction conditions are influencing the directing effect of the -NH, group. Explain why this occurs, using both words and structures.

True or false? (No need explanation) different types of gloves protect against different types of chemicals.   The most likely route of entry for exposure to chemicals is through your nose and mouth.   Never expose yourself to any meterial unless you know exactly what it is, how it can hurt you and what you need to protect yourself

Below are 3 real life situations. Pick two (2) them and explain ALL the science involved in the scenario. This means describe things like what is happening to the gas/liquid/solid molecules or atoms, which principles or laws are at work, why what is happening is happening, and how you know.  At sea level, a pot of water will boil at 100 °C. Suppose you wanted to boil the same amount of water high in the Rocky Mountains. What do you expect the temperature will need to be (generally speaking)? Why?   A can of soda sits in a sunny spot on the window sill for several hours. It is then opened at the same time as a cold can of soda from the refrigerator. What happens and why?   Weather balloons do not float out into space. They reach an altitude of about 15 miles above the surface (3x the height of Mt Everest) and they burst. Why?

How do I calculate the volume I recorded with a 10 mL pipet?

1.There 17 quips in 1 flop. There are 0.381 flops in 1 trot. There 5.5 trots in 1 maps. How manga cubic trots (trots^3) in 1.25 cubic flops (flops^3)
