Line Structures for Haloalkanes

When drawing the line structures for haloalkanes, do we draw a bond attaching the halogen atom to the carbon atom or do we just write it next to the carbon?

Settin Up An Overall Rate Law

When eliminating an intermediate from an overall rate law, do we always subtract the rate laws to set up the net rate?

Re: Clarification on Heat Capacity and Specific Heat Capacit

Hi, Yes, heat capacity is an extensive property, meaning that the heat required to increase a substance by 1 degree Celsius depends on the amount of substance. However, specific heat capacity is an intensive property, so it is not dependent on the amount of substance. The specific heat capacities fo...

Writing out a Coordination Compund

If I were to write the formula for tetraamminechloronitrocobalt(lll)chloride, how do I know in which order to write the ligands? Does the order matter? For example, [Co(NH3)4(NO2)Cl]Cl vs. [Co(NO2)(NH3)4Cl]Cl?

Re: Naming in textbook problem 29. d)

It is not incorrect to put mono-, it just isn't used commonly. It is similar to the way we write the term x in math instead of 1x. We just assume the 1 is there.

Re: hybridization

Hybridization allows one to understand why a molecule has sigma bonds or pi bonds and gives a better representation of how the orbitals are interacting with one another, so it should not be considered as a revision, but as a visual tool of what is actually taking place.

Diffraction Patterns

This question is from the Wave Properties of Electrons and The DeBroglie Equation Module Assessment: When neutrons pass through a crystal is a diffraction pattern observed? I'm not sure whether neutrons display a diffraction pattern or not.
