For this problem, we use the Faradays law to relate the mass electroplated and the current passed through. We do as follows:
60.1 g (1 mol / 196.67 g) (1 mol e- / 1 mol Au) ( 96500 C / 1 mol e- ) = 29486.25 C
Q = It
29486.25 = 5t
t = 5897.85 s = 98.30 min
Hope this answers the question.
Answer:
Yes
Explanation:
Chemical reactions often involve changes in energy due to the breaking and formation of bonds. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic.
Answer: materials and design Techniques that reduce the negative environmental impact of a structure
Explanation:
When sunlight hits the moon's surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C).
