predict the standard cell potential for the process and whether or not this cell would function as diagrammed (spontaneously)Fe^0(s) + Sn^2+ (aq) -----> Fe 2+ (aq) + Sn^ 0 (s) occuring in the galvanic cell:Fe^0/Fe^2+(1.0M)/Sn^2+(1.0M)/Sn^0
half reactions
Fe^2+ + 2e ---> Fe^0 E red = -0.409 voltsSn^2+ + 2e ----> Sn^0 E red = -0.14 volts
A fuel with the potential to supplement if not replace gasoline, formed from the fermentation of surgars by the action of yeasy is called
As a reference, a standard mixture containing 2.26 micrograms Co/mL and 1.92 micrograms Ti/mL was prepared and measured to have a signal-to-signal ratio of 2.41 Ti: 1.00 Co.
The vapor pressure of water at 32 C is 35.7mmHg. What is the vapor pressure of water-ethylene glycol solution at 32 C? Ethylene glycol is non-volatile.
sodium bicarbonate is called baking soda because when heated it releases carbon dioxide gas which is responsible for
