In the following chemical equation, what is the reactant? CuSO4·5H2O(s) ® CuO(s) + SO3(g) + 5H2O(l)
what amount of heat is produced? The specific heat of aluminum is 0.90J/g C?
Determine the minimum concentration of the precipitating agent on the right to cause precipitation of the cation from the solution on the left.
The Henry's Law constant (k) for carbon monoxide in water at 25ºC is 9.71 x 10-4 mol/(L•atm). How many grams of CO will dissolve in 1.00 L of water if the partial pressure of CO is 2.75 atm?
When 35.0 g of an unknown nonelectrolyte is dissolved in 220.0 g of benzene, the solution boils at 83.2°C. Calculate the molecular weight of the unknown nonelectrolyte. The Kb for benzene = 2.53°C/m. The boiling point of pure benzene is 80.1°C.
Calculate the [Zn2+] in a solution of ZnC2O4 held at a pH of 3.00. Remember C2O4^2- is a weak base so you must consider other equilibria. (Ksp(ZnC2O4)=7.5X10^-9, Kb1=1.8X10^-10, Kb2=1.8X10^-13).
What is the energy change when the temperature of 12.3 grams of solid tin is decreased from 38.1 C to 24.7 C
solution requires 14.45 mL of 1.00 M NaOH for titration. How many molesof HCl are present in the solution? The density of 3 M HCl is 1.05 g/mL
Calculate the delta Hrxn for the following equation- 4KNO3(s) - - > 2K2O(s) + 2N2(g) + 5O2(g)
convert back to molarity. And since it is a strong acid, you would just take the -log(KOH or OH-) then subtract this number from 14. From this I get 11.85, however the answer is 10.98. Can somebody tell me where I'm going wrong in detail?
Calculate the mean percent of hydrogen peroxide when three determinations were 3.03% , 2.89% and 3.22%
Write the complete mechanism for the reaction of the above molecule with HCl. Used curved arrows to indicate the formation or breakage of covalent bonds, label all charges, and show each step separately.
A mysterious material was purified from safflower oil (hint: full of fatty acids). Upon ozonolysis it gave the following compounds in their respective molar ratios.
