Hi guys..... i urgently need a damm gud chemistry project for my school assignment....... Recently i got a idea abt estimation of nickel content in food.......especially in chocolates...........but didn't get any methods to find so.......Do any one of u know....anyway to do this???>........i have to estimate the amount of nickel......or test the presence in excess in chocolate.....

hai visit http://www.sciencebuddies.org for simple ideas.....

well....also the simple water electrolysis which can be shown...... veggie power (electricity from vegetable)......

what was the distance between u and the object? Describe the structure. Where did u see the ship? tell the state and city. I am also from India.

the 3 motion formulas can be used v = u + gt s = ut + 1/2 gt^2 v^2 = u^2 + 2gs

got it G = 6.67 × 10−11 N m2 kg-2

it said to collect some form of radiations

I heard that ( i have seen) a huge plasma develop when we keep a candle in microwave!!!!!!!!!! what is it??

how is that we gulp in air with drink????????

u r right........i always experience that.

isn't wave and particle by the substitution of planks equation and e = mc2

some scientist created a equation to derive pi. anyone knows???

sorry,...........guys. it was pi

can anyone help me how to derive pie the value is commonly known as 22/7 and it is circumference by diameter. but is it broughty in no.???
