Can you jump thru loopholes in time?
in other words.. instead of traveling from point A to point B
you BEND the spectrum until A and B are one and the same
therefore you never really travel at all.. you just jump thru the bend.

hello! so in my handout, the equation is
2Na + Cl (2) --> 2NaCl
the (2) means it's subscript 2
and then it says:
If you want to make 82.59 grams of sodium chloride, how many grams of each reactant are you going to need? Write both answers as complete sentences.
i got the sodium thing, yes. but for chlorine i'm not sure how it works because it's a gas, right? so am i supposed to have the ratio be 1 L Cl (2) / 2 mol NaCl
or should i just leave the ratio like 1 mol Cl / 2 mol NaCl?

If we write
x^(n) = a^(m) - b^(m)
I need to prove that for finding natural solutions of "x" , "a" & "b" Either "n" Or "m" should be 2 (not >2).
Can u help me out?
