A single drop of water is injected into a balloon at 25C that contains ammonia, at 1 atm. What will happen to the V of the balloon?Assume Henry's constant is ~0.02 atm/M

physics
suppose you exert 150N on your refrigerator and push it across the kitchen floor at constant velocity. a. is the friction force equal and opposite to your 200N push? explain b. does the friction force make up the reaction force to your push?

chemistry
Exactly 10mL of water at 25 degrees C was added to a hot iron skillet. all of the water was converted into steam at 100 degrees C. If the mass of the pan was 1.20 kg and the molar heat capacity of iron is 25.19 L/mol*C, what was the temp change of the skillet?

chemistry
During a strenuous workout, a student generates 2000 kJ of heat energy. What mass of water would have to evaporate from the student's skin to dissipate this much heat?

algebra
How do you graph this liear inequality 2y greater than equal to 4x-6

physics
Water flows into a swimming pool at a rate of 9.59 gal/min. If the pool dimensions are 30.9 ft wide, 47.6 ft long and 13 ft deep, how long does it take to fill the pool? (1 gallon = 231 cubic inches). Answer in units of minutes.
