Derivation of Ideal gas equation from the Kinetic theory
For the following electrochemical cell Cu(s)|Cu2 (aq, 0.0155 M)||Ag (aq, 1.50 M)|Ag(s) write the net cell equation. phases are optional. do not include the concentrations
enzyme1 (E1) is required to convert reactant B to product C. Enzyme 2 (E2) is required for the reverse reaction (C to B). The activity of E1 is 50 pmol of C created/10^6 cells *s and that of E2 is 40 pmol of B created/10^6 cells*s.
If the Ksp of KHT was determined experimentally to be 3.8E-4 at 25 C, calculate the mass of KHT needed to make 200 mL of saturated solution.
How would (The weak base sample was impure, containing about 5% inert material) affect the values of Ka for the weak acid unknown and the values of the molar mass for the disodium salt
if you make a mistake and deliver less than 50.00 ml of hcl to the erlenmeyer flask what effect will this have on the
Explain what is the minimum value of K the partition coefficient that would allow for the extraction of 99.95% of a solute from 100mL of water with five successive 50mL portions of ether
In addition to long strings of carbon atoms, another common type of carbon structures, which are generally pretty smelly, come in the form of
Write the names of the following compounds. Use proper spacing and spelling. (a) AgNO35 H2O (b) KCH3CO26 H2O (c) Ca(OH)24 H2O
A chilled carbonated beverage is opened and allowed to warm to room temperature. Will the pH change, and if so, how will it change. loss of CO2 from the beverage (Henry's Law) will result in a decrease in the pH
Dry ice sublimes at room temp. If 10.0 g of solid dry ice is placed in a 400 mL container, what will be the pressure in the container at 35 degrees C
How many liters of CH4 (g), measured at 23.4C and 768mmHG, must be burned to provide the heat needed to vaporize 3.78 L of water at 100C? DeltaHcomb= -8.90x10^2 KJ mol CH4. For H2)(l) at 100 C, d= 0.958 g cm and deltaHvap=40.7KJ mol.
