Explain how to prepare 0.250 L of a 0.500 M CuSO4 solution. 1. Measure out 0.500 moles of CuSO4 solid 2. Measure out 20.0 g of CuSO4 solid 3. Measure out 0.500 moles of CuSO4 solid and add water until a volume of 1.0 L is reached 4. Measure out 20.0 g of CuSO4 solid and add water until a volume of 250 mL is reached
The standard free energy (?G0') for the hydrolysis of ATP is -30 kJ/mol. The free energy for the hydrolysis of ATP in the cell (?G) is -50 kJ/mol. Which number is closest to the ratio of [ADP][Pi]/[ATP] found in the cell? R=8.314 J/mol*K T=310K An..
If 0.90 mole of MnO2 and 48.2 g of HCl react, which reagent will be used up first?
determine partial pressure and number of moles of each gas in a 17.25 L vessel at 30 degrees celsius containing a mixture of xenon and neon gases only.
A refrigeration system contains 575 ml of a gas at 22 degrees C and 1.25 atm. The gas is compressed until it has a pressure of 2.00 atm and a temperature of -6 degrees C. What is the new volume of the gas in the system
What evidence do you have that your product consists of a single geometric isomer or is a mixture of isomers? Does the melting point give such information
The hypothesis that hemoglobin shifts between a low and a high affinity form implies that the protein
