A sample weighing 25g starts at 99 degrees celsius. It is put in a calorimeter containing 100g water. The water temperature begins at 20 degrees and both water and sample reach equilibrium at 32 degrees. What is the specific heat of the sample?
525mL of 1.50M NaCl is added to a beaker containing 378mL of 2.22M AgNO3, resulting in the formation of AgCl precipitate.
H2 and Cl2 combine to form HCl. In a gas phase equilibrium mixture of H2, Cl2, and HCl at 300 K, [HCl] = 0.0036 mol/L and [Cl2] = 0.00485 mol/L.
If 21 mL of 6.0 M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid?
The first step in the industrial recovery of zinc from zinc sulfide ore is roasting, that is, the conversion of ZnS toZnO by heating: calculate the heat of reaction
If a 100.0 g sample of water at 60.0 degreesC is added to a 100.0 g sample of water at 10.0 degrees C, determine the final temperature of the water.
calculate the volume of water needed to dilute the anti-freeze from 0.20M in 0.260 litres to 0.13M.
Use Hess' Law to show how the titration of acetic acid with sodium hydroxide can be expressed as the combination of two reactions: the acetic acid reacting with water, and the sodium hydroxide reacting with hydronium ion.
