When o.514 g of biphenyl (C12H10) undergoes combustion in a bomb calorimeter, the temperature rises from 25.8 to 29.4 degree Celcius. Find delta energy reaction for the combustion of biphenyl in KJ/mol biphenyl. The heat capacity of the bomb calorimeter, determined in a separate experiment, is 5.11 KJ/Degree Celcius.
When 30 mL of a 365 mL stock solution containing 1.8999999999999997 M AlCl3 is diluted to 81 mL, how many moles of Cl- are in the new solution?
if molarity of a 2000ml solution is 4.0M NaCl, how many moles of NaCl are dissolved in that solution.
how many grams of calcium carbonate , CaCO3, do you need in an antacid tablet to neutralize 20 ml of stomach acid ?
The Greenhouse Effect - how the sun's visible light is converted into trapped infra red light and heat, causing the planet to warm up.

Describe and explain the possible effect on your results if you mistakenly extracted the dicholoromethane solution with 5% HCL rather than 5% NaHCO3
At 1045K the partial pressures of an equilibrium mixture of H2O (g), H2 (g), and O2 (g) are .040, .0045, and .0030 respectively. Calculate the value of the equilibrium constant Kp at 1045K
Draw all stereoisomers of 1,2,3-trimethylcyclopentane. Use bold and hashed wedges to show the stereochemistry.
For the Reaction CO(g) + Cl2(g) -> COCl2(g), the rate constant increases 1500 times when the temperature rises from 150C to 250C. Calculate the activation energy, in kJ/mol, for this reaction. Assume frequency factor is constant for both temperatu..
