What is two?
400
According to Faraday's first law, the quantity of electrical charge transferred by an electric current depends on the _________ of the current and the ______ for which it flows
What are the magnitude and the time?
500

What is that animal tissue contained a "vital force" or "ANIMAL ELECTRICITY"?
500
The components of the Voltaic Pile (the first direct current battery)... that "took the world by storm!"
What is (explanation must include all components - alternating disks of zinc & silver, separated by moist cloth or cardboard soaked in concentrated salt solution, with wire attached to the ends)
500
Name two other famous works of Sir Davy
What are; 1) the Davy Lamp (used by coal miners) 2) the use of N2O as an anaesthetic 3) that hydrogen, not oxygen, was responsible for the characteristics of acids!
500
His fundamental laws of electrolysis govern this
What are quantitative relationships in electrolytic processes?
500
According to Faraday's second law, if electrolytic cells are connected in _______, the numbers of ______ of products at the electrodes are in simple ratios of each other. (This allowed Helmholtz to conclude that electricity must be made up of "tiny packages" in accord with the "atomic theory of matter")
