If 200 g of water at 20 degrees celcius absorbs 41840 J of energy, what will its final temperature be
Consider the following cell: Pt|H2(g, 0.670 atm)|H (aq, ? M)||Ag (aq, 1.00 M)|Ag(s) If the measured cell potential is 1.15 V at 25 °C and the standard reduction potential of the Ag /Ag half-reaction couple is 0.80 V, calculate the hydrogen ion con..
The smallest unit of charge is -1.6× 10-19 C, which is the charge (in coulombs) of a single electron. Robert Millikan was able to measure the charge on small droplets of oil by suspending them between a pair of electrically charged plates.
