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
the answer to this question is option a which is a compound.
it is because zoe is investigating the composition of substance a, an unknown substance.
using chemical processes, she analyzes substance a and determines it is composed of sodium, oxygen, and hydrogen atoms in a ratio of 1 : 1 : 1.
finally, she found that the substance is a compound.
when the top of the pencil moves in one direction, the bottom end on the ground will move in another, but due to the frictional force it will move by a lesser amount, and the center of mass of the pencil will be accelerated in the horizontal direction due to the force of friction
there's one weather forecasting technique known to meteorologists as 'persistence.' persistence means 'what again be." in other 's weather will also be tomorrow's weather.
in some 's not a bad technique.
think of sunny southern california where the weather is pretty much the same day in and day out.
in most most 'persistence' technique would be the least useful tool to predict tomorrow's weather.
i hope this : )
