If a balloon containing 1,200 L of gas at 25C and 760 mm Hg pressure ascends to an altitude where the pressure is 380 mm Hg and the temperature is 54C, the volume will be?
It is important to know if a particular molecule is composed of elements with different electronegativities as well as the structure of the particular molecule to explain the physical properties of the molecule.
Calculate the equilibrium constant for the reaction - flask at a certain temperature according to the reaction
During the course of an experiment, a 0.300 M NaCl solution with an initial volume of 25.0 ml is diluted to a total final volume of 26.0 ml. What is the concentration of NaCl in the final solution?
What is the solubility of AgCl when it is in a solution of 0.15 M NaCl? (AgCl has Ksp = 1.8 x 10-10.) Make a reaction table. Include rows for initial concentration, change in concentration, and equilibrium concentration.
Explain how does unique physical and chemical properties of water contribute to significance of water for life on Earth to survive.
Suppose your thermometer read consistently 1.0 o C lowered throughout both parts in the colligative properties lab. What effect would that have on your experimental value for the molar mass of your unknown solute?
The feed to reactor contains only C 2 H 4 and HBr. if the molar flow rate = 165mol/s, compute the fractional conversion of the limiting reactant?
