Question: wut are some Science Experiments that u could do with school aged children?

I need a few web sites 4 that as well as pictures for that

Answer: I don’t have websites off the top of my head but I do suggest you look into the book… The Mailbox Magic Moments- Super Science With Your Kids for ages 5-10. Check your local library. I’m sure that Amazon.com or Barnes and Noble have this in stock. It gives explanations and color descriptions and step by step directions. I’ve used many of them when I worked with school-agers.

Question: PLEASE i have NO IDEA what to do on this TITRATION lab experiment question? i would appreciate some help ?

I did an experiment and found that the mean concentration (M) of HC2H3O2 (acetic acid) is 838. I also initially had the molarity of NaOH to be 0.25, and the volume of NaOH to be 34 mL.

they are asking me this:

the manufacturer of the vinegar used in this experiment claims that the vinegar contains 5% acetic acid by weight. Use your results and a density of 1.0 g/mL to investigate this claim.

thank u
oops, i meant the acetic acid’s molarity was 8.38 M

Answer: Wow, 838 M acetic acid? Are you sure you didn’t do something wrong? The most concentrated I’ve used was 15-20 M acetic acid.

I would say that the manufacturer of your vinegar is trying to kill you if they wanted to sell you 838 M acetic acid, or you got a really good deal.
