Re: Steric vs. Torsional

When rotating a molecule around a bond, the torsional strain is the repulsion caused by the electrons in between different groups when they pass by each other. Steric Strain is strain caused by the electrons in between different groups. Steric strain cannot be lessened by rotating the molecule aroun...

Re: Final Exam Details and Review Sessions Winter 2017

Will the TA's have example problems at the review sessions? Or will they be centered more around student questions?

Re: Intermediates in pre equilibrium

I think the review session today is limited to the midterm and questions within that. But Do you know if there will be any review of the new organic material?

Significant Figures

When doing old quiz problems to practice, I noticed that significant figures were supposed to be done at the end rather than step by step. Should we do sig figs as we go at each step or just at the end?

Re: Sig Figs

In general, sig figs apply only within the numbers you use for your calculations.

Re: Sig Figs: Rounding Off

If there is a question with a number that has the least amount of significant figures and that value is not used when calculating for the answer, do we use those number of significant figures still or the number of significant digits from a number that is used when calculating that is the least?

Re: Example of isolated System

The entire universe is an isolated system which is why energy is conserved.

Re: -q(Rxn)=q(cal)? [ENDORSED]

The bomb calorimeter is actually an isolated system which means that nothing can exchange with the surroundings.

Re: Sublimiation

If a vapor changes into a solid, this is known as deposition which is the opposite of sublimation.

Re: Standard Reaction Enthalpy of O2

Standard Enthalpy of Formation for elements in their standard state is 0 and the standard state for Oxygen is O2 gas. The standard reaction enthalpy is sum of the products minus the sum of the reactants. So if you have just O2 then this is an element in its standard state which means that the Standa...
