A student is provided with a 12.0-V battery of negligible internal resistance and four resistors with the following resistances: 100 Ohms, 30 Ohms, 20 Ohms, and 10 Ohms. The student also has plenty of wire of negligible resistance available to make connections as desired. 1. Using all of these components, draw a circuit diagram in which each resistor has nonzero current flowing through it, but in which the current from the battery is as small as possible. 2. Using all...

Mass of the calorimeter cup = 60 gm; mass of water= 100 gm; water equivalent mass of coil =2.5 gm; initial temperature of the water = 20° C; final temperature of water in cup = 41° C; total heating time = 20 minutes. Using this initial data set, complete the rest of the data sheet. Take the specific heat of the water as 1cal/gmº C and cup as 0.22 cal/gmº C. The average current and voltages are 2.75 A and...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
