Under the standard conditions of 1 bar pressure and 298.15 K,the equilibrium constant Kp for a gas phase reaction is 5.30E-13.Calculate the value of the Gibbs free energy change G,std for this reaction (under standard conditions at 25degC). Enter your answerin kJ.
Draw the structures of the ketones with the molecular formula C6H12O that have a four-carbon chain. Do not consider stereochemistry
The lid is tightly sealed on a rigid flask containing 3.50 L H2 at 17 °C and 0.913 atm. If the flask is heated to 71 °C, what is the pressure in the flask?
When carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 18.0g of carbon were burned in the presence of 62.3g of oxygen, 14.3g of oxygen remained unreacted. What mass of carbon dioxide was produced
a student placed 13.5 g of glucose c6h12o6 in a volumetric flask added enough water to dissolve the glucose by swirling
If 28 mL of a .537 M NaOH solution is needed to neturalize 20 mL of a carbonic acid (H2CO3) solution, what is the molarity of the carbonic acid? (Write a balanced chemical reaction first.)
My paper says that will be only one isomer out of hexabromobiphenyl, C12H4Br6 And it states also that one phenyl group is still the active substituent when it is bromized. I wonder why it is only one isomer and I will be so thankful if you can dra..
What is the osmotic pressure of a solution made from dissolving 85.0g of glucose in 800ml of water at 19.0 C.
The concentration of NaCl in solution is 0.25 M. What volume of solution contains 5.0 g NaCl.
Sample were collected in a zinc smelter to determine the exposure of a furnace tender to lead fume during his normal work duties which involves "furnace draws" and general activities around the furnace.
The molar heat capacity of SO2 is given by the following equation: Cpm= 3.093 + 6.967x10^-3 T/K -45.81x10^-7 T^2/k^2 + 1.035x10^-9 T^3/K^3. Calculate delta S for the heating of 1 mol of SO2(g) from 75C to 1350C at a constant pressure of 1 bar
