What is the resulting temperature when 35 g of water at 75C is mixed with 15 g of water at 15C? (The specific heat of water is 4.184 J/g x C.)
Would you help me to determine the term symbols allowed by the Pauli exclusion principle for the electron configuration 3d2 . Order the terms from lowest energy to highest.
What is the percent yield of a reaction in which 216 g phosphorus trichloride reacts with excess water to form 134 g HCl and aqueous phosphorus acid (H3PO3)
Buffering Action of Proteins, We did this experiment in class but I want to see if the results seem reasonable and, if so, why they were not more varied.
In one city, a balloon with a volume of 6.0 L is filled with air at 101 kPa pressure. The balloon in then taken to a second city at a much higher altitude
If I have 7.0 moles of gas at a pressure of 0.10 atm and at a temperature of 50.1 degrees C in a balloon, what is the volume of the balloon? (Round to one decimal place.)
