who can get this right?

1a) Nickel exists as a mixture of 3 isotopes nickel-58, nickel-60 and nickel-62

i) Define isotopes
ii) Complete the table o show the atomic structures of the 3 isotopes

isotope | Protons | Neutrons | Electrons
Ni-58 ..|.........|..........|..........
Ni-60 ..|.........|..........|..........
Ni-62 ..|.........|..........|..........

hint: u will need a periodic table for this question


maths
solve the simultaneous equations
1) y+x^2 & 6x+y=7
2) y=x+1 & xy-4x=10

3) what does the graph of x^2+y^2=4 look like?

im not doing all your homework you know!

and you thought he wasn't that smart wallace.....

(I told you you need to cover it up a bit more)

wow! I never even did Chem for Leaving cert level (alevels) and I can do that question

This was my French homework from last year:

Qu'est-ce que tu fais ce week-end?
