Hi,

Just a random question...how are these so-called greenhouse gases cause global warming? Is there a chemical reaction taking place?

Yes, agree with the other answer. These gases give a blanket effect trapping heat. So, the earth's temperature increases which leada to global warming.

Thanks for your inputs. Helps me also.

Hello,

How does paper chromatography works in separating mixture of solutes in a solution?

I think it is measured through the different speeds of different solutes travelling on the paper. It has different speeds so eventually they are separated..

...For printer, buy Brother or Canon, better?...

Canon was advertising some products at a good price. You can also scan/ print from your mobile phone.[/quote]

Wow! Really direct from your mobile phones? This sounds great! How about the consumables like the ink or cartridges? Is it not too expensive?

What do you think are the pros and cons in getting help from a chemistry tuition? Need to collect this to decide whether to get one or not.
