For the reduction of Iron(III) to Iron(II) by an applied potential starting at +300mV and stepping to a applied potential of -500mV, in a diffusion limited environment with a planar electrode, plot the charging and faradaic currents at 298K
At 212 mm Hg and 24 °C, a sample of gas occupies a volume of 125 mL. The volume is increased to 325 mL and the temperature is reduced to -5.0 °C. What is the final pressure of the gas in the flask?
How many grams of sulfur (S) are needed to react completely with 369 g of mercury (Hg) to form HgS?
isopentyl alcohol with an excess of acetic acid, how many gras of isopentyl acetate( MW =130.2 g/mol) would you hav if the yield was 75%?
required to heat 10.0 grams of silver (Ag) from 112 degrees Celsius to 275 degrees Celsius
How do you calculate the percent by mass of volatile water in hydrated salt and average H20 when the mass of hydrated salt
What is the heat change in J associated with 74 g of gaseous butane at 91 oC changing to solid at -170 oC? c(butane) (gas) = 2.31 J/ (g.K) c(butane) (liq) = 1.65 J/(g.K) c(butane) (s) = 1.32 J/ (g.K) ?Hfus(butane) = 6.885 kJ/mol
