E. 62.5 mL
Please provide the answer of the given question on urgent basis
Calculate the freezing point and normal boiling point of each of the following solutions: a.25.0% by mass glycerin, C3H8O3, in water b.28.0 g of propylene glycol
What product would you expect to make? Propose a detailed reaction mechanism for this reaction. What by-products might be expected in this experiment?
if a molecule of no diffuses a distance of 0.778 m from a point source calculate the distance m that a molecule of he
The utilization of the British thermal unit (Btu) is common in much engineering work. A Btu is the amount of heat needed to raise the temperature of 1 lb of water by 1 degree Farenheit. Compute the number of Joules in a Btu.
What effect will increasing the temperature have on the system? Fe3O4(s) + CO(g) ?? 3 FeO(s) + CO2(g) DH°= +35.9 kJ A) No effect will be observed. B) The reaction will shift to the right in the direction of products.
Compare this energy ( 23 Joules) to the amount of energy absorbed by a person's body if they jumped from a chair to the floor (assume that all of the energy from the fall is absorbed by the person and h=0.5 m).
A mixture of 0.156 moles of C is reacted with 0.117 moles of O2 in a sealed 10.0L vessel at 500.K, producing a mixture of CO and CO2. The total pressure is 0.640 atm. What is the partial pressure of CO
5H2C2O4 + 2KMnO4 --> 10CO2 + K2SO4 + 2MnSO4 + 8H20, How many g of H2SO4 are required to produce 75g of CO2
2HCrO4 ^- Cr2O7 ^2- + H2O Determine concentrations of Dichromate ion and Bichromate ion if we add .1mol/L of bichromate ion and no dichromate ion once reaction reaches equilibrium.
In solution in 6EB in Atkins 9th edition is not clear to me. The equation for the location of partile in the box is different from the one that is in the book.
A volume of 125 mL of H2O is initially at room temperature (22.0*C). A chilled steel rod at 2.00 *C is placed in the water. If the final temperature of the system is 21.1*C, what is the mass of the steel bar?
If we start with a partial pressure of 300 torr for the N2O5 and zero for the products, the equilibrium pressure of the N2O5 will be 150 torr. However, if the original pressure of N2O5 is now 125 torr, what will the partial pressure of NO2 be when..
