A solid sphere of radius 40.0 cm has a total positive charge of 26.0 C uniformly distributed throughout its volume. Calculate the magnitude of the electric field (a) 0 cm, (b) 10.0 cm, (c) 40.0 cm, and (d) 60.0 cm from the center of the sphere

An aerosol spray can with a volume of 441 mL contains 3.09 g of propane gas as a propellant. What volume would propane occupy at STP?

Refrigerators are usually kept at about 5^C, while room temperature is about 20^C. If you were to take an "empty" sealed 2-liter soda bottle at room temperature and place it in the fridge, would you expect it to contract to one-fourth its original volume?

Suppose you accidently add too much NaOH during the titration. You then add a volume of HCl exactly equal to the volume of NaOH actually used in the titration. What effect does this have on the Ka

Consider 1.00 L of air in a patient's lungs at 37.0 C and 1.00 atm pressure. What volume would this air occupy if it were at 25.0 C under a pressure of 5.00 102 atm (a typical pressure in a compressed air cylinder)

A solution is prepared by mixing 93.0 mL of 5.00 M HCl and 36.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+ ], [OH - ], and the pH for this solution.
