I am doing a project for science. I need to find 20 products from my house that have one elements from the perodic table like iron, calcium, lithium, berylium, carbon, silicon, argon, neon, cobalt, lead, etc... I need to do this project by October 16, 2006. I need to do the project on 20 different elements. I have looked every where for elements but I cannot find any in the ingredients of the products. The product can be the pure sample of the element, compound, or mixture. My teacher prefers for the product to be pure. I need label as evidence that the product does have the element. I would really appreciate your help.

You should be able to find (1) iron in vitamin pills, (2) calcium in milk or orange juice, (3) carbon in charcoal, (4) argon in fluorescent light bulbs, (5) silicon and (6) gold in computers. (7) Oxygen and (8) hydrogen in bottled water. Salt contains (9) sodium and (10) chlorine. Meat products contain (11) nitrogen. Regrigerator magnets may contain (12) nickel. Electrical wires contains (13) copper. Lithium ion batteries will contain well (14) lithium. (15) Potassium nitrate is used in gunpowder, for those who have guns at home. Compounds of (16) fluorine, including sodium fluoride (NaF), stannous fluoride (SnF2) and sodium MFP, are used in toothpaste to prevent dental cavities. (17) Zinc oxide is used as a white pigment in watercolours or paints. (18) Sulfur is used in matches. (19) Titanium is used in watches, eye glasses and cookware. Lastly, (20) Magnesium can be found in spinach, peanut butter, and black-eye peas.

Calcium is obvious - milk
Iron is obvious too - vitamins
Lithium - unless you're crazy, you're not gonna have any - unless you can find and old digital watch.
Berylium - can be found mixed with copper to make it harder - so get a penny.
Most everything contains carbon - use a plant as an example
Silicon - your computer
Argon - Light bulb
Neon - Get a bar sign - maybe a fluorescent tube light
Cobalt - be creative, get a pic of a Chevrolet Cobalt - otherwise don't know.
Lead??? Stay the hell away from lead if you know what's good for you.

what are the instruments for the charges? i.e. human beings/12 months etc? i assume this question demands a sprint extra history.. ought to the 0.05 be a 5% enhance according to 12 months? if so you will possibly desire to calculate the quantity of years necessary to double the present (probably given?) inhabitants if the upward push is 5% according to 12 months, which you will recalculate each and every time with the hot values. the doubling time equation is T(d) = (log(2)) / (log (a million + annual enhance %)) so... i'm thinking this problem is asserting the each and every year enhance fee is 5%, so log2 / log1.05 = extensive style years. (approximately 14.21) i'm assuming the values are for annual costs, however.

Find a banana for potassium. :) A helium balloon for - well, I'll let you guess that one. A glass of water contains oxygen and hydrogen. A box of empty air contains nitrogen. Salt contains sodium and chloride, toothpaste often contains flouride. Tap water probably contains trace amounts of chloride and flouide as well.
