Do you know any link of a page which describes the experiment about light or water and plant growth?

I need to do a experiment to research effect of light or water or transpiration rate of some flowering plant growth.

Chemistry please help?

In an experiment, 50.0 ml of 0.0800 mol/L NaOH is titrated by the addition of 0.0500 mo/L HNO3.What is the hydroxide ion concentration after 30 ml of HNO3 solution has been added?

Ways to make your hair grow faster?

Stay away from heat products. Don't wash your hair every day. Have a healthy diet. Sleep for at least 8 hours a day. make sure you have no dead ends. Otherwise your hair will split, slowly rip off and your hair will never grow. And try not to brush your hair more then twice a day.

I did this experiment,can someone explain this to me?

i add 10 drops of silver nitrate solution to 5 drops of bromoethane and shake vigorously. Test the solubility of the precipitate with a few drops of dilute nitric acid. why does it change color to milky?

What kind of pipe should i buy?

hey guys so i want to buy a weed pipe for college (im going to Columbia) and im not sure what to buy. I am not stupid with weed i smoke it at parties and when im stressed out. I dont like to smoke too much at once, but i like having my own piece because everyone has personal preference. I saw these mini pipes at the store which looked good but i like using my friends bubbler. I hate bongs (too strong for me) and i hate joints and blunt because they waste money and weed. I just need something that will last my first year at Columbia and would be nice to just have. And for all those against weed (i know there are people on here that think weed is the worst thing ever) weed was proven by tests and experiments that it is safer and smarter to use than alcohol or any other drug out there. i dont drink at all and i dont plan on trying weird drugs. Any suggestions please let me know

I'm trying to watch a video on loombo but it won't let me?

Not just you ... other sites that use JW Player are also down -- Frog Movz and Karamba Vidz ... not a good sign ... lots of free video sites are getting knocked off the superhighway ... channelsurfing.net went down a few months ago

Is it safe to use a little vial of anti-flea drops on your dog that's out of date since Feb 1st 2011?

We just washed her (a Yorkie) and dried her and then were going to apply the drops but noticed they are out of date. We're erring on the side of caution and not using it but maybe it is actually ok to? Thanks.
