thank you ALisha for answering my question. you just did my homework

For that part I thought that the formula would be NiF2.

I HATE CHEMISTRy

Those are all the numbers in the problem. I worked further in the problem and found... (a) 15.9/20.29= 78.54% and for part (b) I found that 20.29g of MgCO3 makes .24mol CO2. So.... Pressure of CO2 = 12.54 atm. Does that seem right?

So that would give you .39 mol. Which would then give you P = 20.77 atm. I see what you are saying about the numbers in this problem. Unfortunately my teachers often gives problems that seem to have something missing, and I don't know what to do about it....

I gave three different answers. Which one looks OK?

That is what I am thinking. Thanks.

When I use the lowest number of digits (i think your talking about .09) I get 4.7atm.

Ok. I did that and I found that Q= 1.64 x 10 ^ -18. I then divided that by 1.6 x 10 ^ -19. The answer I got was 10.23. I am being told that is the wrong answer. Could you please double check that for me? Thank you!!

I submitted it online and I was told it was wrong. I also tried 10.22 and 10.24 to see if there was a rounding error.

I just realized that the answer had to be 10. Im sorry for any confusion. Thank you for your help though.

great thanks a lot, soz bout double post

it depends on whether (a t3) is (a*t3) or if it is (a+t3.)if (180s) is one term as well then. your expansions are either for (a*t3)(1) 180s*a*t3 or for (a+t3)(2) (180s*a)+(180s*t3)

ok it can sometimes be easier to put in an equation of sorts. 6,279,000,000=2,556,000,000 * x then we multiply x by 100 to get % making x the %increase then just solve for x so 6,279,000,000/2,556,000,000=x x=2.4566 then multiply by 100 =245.66% now this...

ok well maybe changing them to decimals then adding will count as another way

on a very basic level decimals are just parts of numbers, like fractions of a whole. with each place to the right being 10 times less than what it was previously eg 0.1 is ten times less than 1 and 0.01 is ten times less than 0.1. this also makes 0.01, 10...

well if F=ma and a=v-u/t (final velocity-initial velocity/time) so combining these two equations we get F=m(v-u/t) which gives us F=mv-mu/t if the car is to stop then obviously the final velocity is zero (now this will give us a negative answer but that i...

if something dissociates then that means that it completely dissolves in a solution. so DrBob222 is completely correct as NaCl, MgCl2 and CaCl2 all dissolve. unlike table sugar. check a solubility table if you are ever unsure.

a=(v-u)/t where v=final velocity, u=initial velocity and t= time in seconds initial is 0 m/s go from here yourself :)

sorry the answer to the original question is 21,100,000. the example i used would be 22,000,000 because this has been rounded to the nearest 100,000 but in doing so we have reached another million, make sense?
