i googled the coastline of mexican gulf! its there

equivalent fractions have the same value after calculation but look different you work them out by dividing the denominator and the numerator by the same number (the numbers on the top and bottom of the fraction)or multiplying but this isn't usually used 60/80 = 0.75 if you divide both sides by ten 6/8 =0.75 divide first fraction by 20 or the second fraction by 2 3/4 = 0.75 divide the first by 4 15/20 = 0.75 these are all equivalent fractions usually you would use the fraction with the lowest numbers eg 3/4 as this cannot be simplified further you cannot divide it and get whole numbers on the bottom and the top hope that helps

sorry it was a copy and paste job should checked it thanks for the help

i have this question for an online assignment and it keeps telling me that 5.47 is wrong. so my guess is that you do need the density...just saying

can you show me how to plug each of them in?

suddenly although

sorry that ssupposed to say 320 K

Here's my work, but it wasn't the correct answer: The two half-reactions: Fe3+ + e- --> Fe2+ E = 0.77 V 2H+ + 2e- --> H2 E = 0 V You multiply the first one by 2, so it looks like the formula above: 2 Fe3+(aq) + H2(g) 2 Fe2+(aq) + 2 H+(aq). Ecell = 0.77 V lnKsp = (2)(96485)(0.77) / (8.314)(298) = 1.1e26 I have a feeling the n (2 in the equation above) is incorrect, but I don't know why. I multiplied the half-reaction of Fe by 2.

I'm not getting the correct answers, sorry. Can you expand on the explanations?

I did the same thing for part b: Flipped the E for the lesser value (Fe half reaction) 0.80 - 0.771 = 0.029, but it wasn't correct.

Thank you she will get it soon!

If you are on the street with cars, ride your bike with the same rules like follow the red yellow and green light? @writeacher
