Thank you for your response, but I am very familiar with carbonyl reduction with sodium borohydride...I just don't understand how it cannot reduce nitro groups. I have played with the mechanism extensively trying to figure out why but I just don't get it
But to the second part of my question...
I need some help with understanding reducing agent selectivity. I recently did a lab where we used two reducing agents (separately) for 3-nitroacetophenone (benzene with a ketone group on an ethyl branch and a nitro group) sodium borohydride and tin in HCl. I know that sodium borohydride can...
Ok I'm starting to get this a little better now but there is one thing that still puzzles me. You said how much "more" acceleration, but the upwards acceleration is going up and gravity goes down so wouldn't the acceleration be (9.8 m/s2 - 1.2 m/s2)? When I do this I get a higher force when the...
So when the elevator is stationary the forces would be equal since it is not accelerating. When it's accelerating upwards the cable should have more tension right?
The way I'm trying to solve it I found the upwards force and the downwards force in a free-body diagram and then adding them. Am...
Homework Statement
An empty elevator of mass 2.7x10 (3) kg is pulled upward by a cable at an acceleration of 1.2 m/s (2)
a) What is the tension in the cable?
b) What would be the tension in the cable if it was accelerating downward at 1.2 m/s (2)?
c) What would be the tension in the...
