In the copper plating solution lab, you placed copper (cu) pennies in vinegar. vinegar is a weak acid with hydrogen ions (h+). when you put the pennies in the vinegar, you should have observed small gas bubbles. what were these bubbles composed of, and how did they form

Which of the following changes will increase the capacitance of a parallel-plate capacitor? (there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates
