hello guys, this is my first topic here
we jut started stochiometry in school and did a lab
we used 12.5g of copper sulfate pentahydrate and mixed it in water
and then we added fe (ii) and slowly heated it
then i decanted the extra water and measured the total mass
it was 2.57g total
i was asked to answer these ollowing questions
someomeof them i know but i don know the balanced equation or percent yiled calculations
1.what is the type of rxn that tok place? double replacement?
2. write the word equation and the BALANced formmula equation for thisreaction. inculde states of matter
its cuso4 + fe = cu + feso4 + 5h2o right? i do not think its balanced though
3.what is the name and formula of the solid product? i do not get what this question is asking me
lol i don't know neof these
i got this too
4.start by using the mass of iron powder and complete the folowing: i can get these if i get the right balanced equation
a.what is the mole ration for this reaction?
b.calculate the amount of moles of product
c.calc the theoretical yeild in grams of the product
5.what is the actual yield of the product?
6.calc the percent yiled of the product
7.based on your calc percent yiled, describe two source of error from your experiment
any help would be appreciated
thing is due tommorow >.< i cqan answer some of these if i know the anwsers to others
thanks, ruth
