Bicycle Mechanics - Chain replacment

My chain decided to explode on my commute today and I stopped at a lbs to buy a new one. Of course the chain and cog didn't like each other, so I replaced the cog as well. Can there be problems with the new chain and my chainring in terms of compatability? There are some nice noises emitting from the ring when I peddle, or does a new chain and older parts need an adjustment period to properly mesh? Thanks.

Not entirely sure what exactly you are asking here, but...

Did you lubricate the new chain after degreasing it? New chains come coated with "cosmoline" a protective agent used to prevent rust in overseas shipping... its like glue for dirt and should be stripped, and the chain properly lubricated with something good. Most bike shops don't do this when they install a chain, for whatever reason. Probably b/c most the bikes we fix get stuck out on the porch again to never see a drop of lube in their lives...

Also, make sure you got the right chain. 7/8/9spd chains are all a bit different

When you use the term "cog" and "chainring" I'm not entirely sure what you are referring to. The rear cassette/freewheel should typically be replaced when changing the chain out, since they wear together. The front chainrings may or may not need to be replaced. Do they look like shark's fins? If so its time to replace.

Are the noises from the ring, or from the chain rubbing the derailleur cage up front perhaps?

Only if you keep on using the same chain for too long! Normally, a cassette should outlast a couple of chains. And the latter are cheaper to replace.

When you use the term "cog" and "chainring" I'm not entirely sure what you are referring to. Since he's referring to the cog and the chainring each in the singular, I inferred that it's a fixie/ss. This gets me wondering: would reverse-mounting the chainring work in this case, since there's nothing about the ring and its orientation that pertains to shifting (as would be the case with a 2x or 3x front)? My understanding is that chainrings and cogs wear on one side of each tooth, and IIRC, I've heard of people reversing the ring/cog to take advantage of the "unworn" side of each tooth, effectively doubling the life of the ring/cog. Anybody else heard of this?

I've done that before when I had a 7 speed. I flipped the chainring and had no problems. Of course I also used a hammer to flatten out the shark teeth on occation.
