When naming alkenes and alkynes, you start numbering at the double (or triple bond) and continue numbering through it. However, if there is a functional group, you start numbering at the C it is attached to, and then move in the direction that would give the double or triple bond the lowest number.

An alkane is a saturated hydrocarbon, which means there are only carbon-carbon single bonds. The -ane part of the naming is what indicates that the hydrocarbon has only single bonds. Alkyls are the substituents in alkanes. When naming the substituent, the ending -ane is changed to -yl. An alkene is ...

The hydroxide ion appears as a reactant in the first step and as a product in the second step, so it was not consumed in the reaction, which makes it the catalyst. This property allows for catalysts to act repeatedly.

Does anyone know any jokes about sodium? Na. Yeah, I know that was sodium funny!

There's an older post about this. But basically you use the 100 g to cancel out with the grams in the density to give you the volume (convert from cm^3 to L), you do it for both water and ice. Then you find the change in volume and plug into the equation for work. In the end you have to convert to j...

Enthalpy is a state function so only the initial and final states matter. So you can do final-initial, which in this case is the enthalpy of the vapor (the final state) minus the enthalpy of the solid (the initial state).
