Given the following cell diagram: cu(s) | cu2+(0.25 m) || no3- (0.71 m) | no (2.1 atm) | pt(s)
(a) write the balanced redox reaction corresponding to the cell diagram
(b) using standard reduction potentials determine ∆ε° (table 19.1 in openstax your text)
(c) determine ∆ε (ph = 4.2)
(d) determine ∆g°
(e) determine ∆g

Earth's axis of rotation is tilted at an angle of 23.5 degrees. what is one change you would see on earth if its axis was not tilted?

Avariable that is not being directly tested during an experiment should be

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
