Boat Conformation

I know when writing the chair conformation, you start with an up axial and switch between up and down as you go around, then the equatorial is the opposite, however, the boat conformation does not seem to follow this same pattern, so is there a pattern to the bat conformation, or should we just reme...

H^+ ions and H20

When writing the equilibrium constant, when do you include the H20's and H+ ions? Because I've noticed in some problems you include them, and in some you do not.

Naming

When naming ketones, does the number have to go in the middle, or can it go in front? For example, does it have to be pentan-2-one or can it be 2-pentanone?

quiz 3 naming organic molecules

For the quiz, do we have to use common or systematic naming? Or will we have to know both and the question will tell us which one to write?

Rate Law

When a problem asks for the rate law of the overall reaction and you are given the slow step with a chemical reaction, a fast step with a chemical reaction, and the overall reaction, do you only write the rate law based off the slow step?

Slow vs Fast reaction

When given the steps with chemical equations, how can you tell which one is the fast one and which one is the slow one?

Half reactions for galvanic cells

When writing the half reactions for galvanic cells, how do you know which element comes first? Also, are the electrons always on the left hand of the equation?

Problem 8.31

The problem asks you to calculate the heat released by 5.025 g of Kr(g) at 0.400 atm as it cools from 97.6 C to 25 C at (a) a constant pressure and (b) a constant volume. Now, I know you use the formula Cp=5/2R to solve for the heat capacity for constant pressure and Cp=3/2R to solve for the heat ca...

Homework 8.73 a

In the solution manual, it says the only bonds broken are double bonds between two carbon atoms, however, there are also hydrogen molecules in the formula for the reactants, why is this?

Bond Enthalpies

In using bond enthalpies to calculate delta h of the reaction, how do you determine which bonds are broken or formed? Do you just break all of them and reform them after the reaction or is there a way to tell which ones to break and which ones to form?
