Nevermind . . . the G value for Br2 isn't 0, which was throwing off my calculations. The answer ended up being 4.96x10^-20
So I have the reaction 2HBr(g) <--> H2(g)+Br2(g) I'm supposed to find the equilibrium constant, K, using free energy (G) values. The values in my textbook for G of H2 and Br2 were zero, and the value for HBr(g) was -53.5. So, to find delta G I did products - reactant...
But then when i try to factor i get 0=t^2-3t-12
WAIT ITS t^2 NOT 3t^2
Logv3(12) = logv3 (3t^2) - logv3 (3t) (the v means "log 3"- 3 is the base)
a proton (mass 1.67 x 10^-27 kg) with a velocity of 1.10 x 10 7 m/s collides with a motionless helium nucleus, and the proton bounces back with a speed of 6.00 x 10 6 m/s. The helium nucleus moves forward with a velocity of 4.00 x 10 6 m/s after the bombardment. What is the ma...
what is the molarity of a sodium hydroxide solution if 26.0mL of the solution os titrated to the end point with 57.5mL of a 0.500M hydrochloric acid solution
A population of 75 foxes in a wildlife preserve quadruples in size every 15 yr. The function y= 75 * 4^x , where x is the number of 15 yr periods, models the population growth. How many foxes will there be after 45 years?
Exponents: Simplify the expression 7ab^-2 / 3w I got 7a3w / b^2 Is this correct?
