The complete combustion of pentane yields carbon dioxide and water. When the equation C5H12(l) + O2(g) ? CO2(g) + H2O(l) is balanced, the ratio of the coefficient of CO2 to the coefficient of O2 is
A) 8:5
B) 8:6
C) 6:5
D) 5:6
E) 5:8
Predict the type of substitution mechanism, predict which reaction of the pair will occur at the faster rate, and draw the correct organic product.
A canister is filled with 320 of ice and 100. of liquid water, both at 0 . The canister is placed in an oven until all the has boiled off and the canister is empty.
Hydrogenation of carbon double bonds C=C (i.e. adding a hydrogen on each carbon atom and thus reducing the double bond into a single bond: H-C-C-H) is a very common process in organic and polymer chemistry
The Haber process is very important for agriculture because it converts N2 (g) from the atmosphere into bound nitrogen which can be taken up and used by plants. The reaction is N2 + H2->NH3
Calculate how much work is needed to perform the compression in the following scenario
Estimate the temperature at which calcium carbonate is likely to decomp under 1atm of pressure. Reaction: CaCO3(s) -> CaO(s) + CO2 (g) For this rxn: dHstandard = 177.8 kJ and dS standard= 160.5 J/K (notice unit differences)
Find the Diffusivity of Ammonia gas(A) in a mixture of nitrogen(B) and hydrogen(C). D(AB)=3.28x10^(-5)m2/s and D(AC)=1.093x10^(-4)m2/s.
Celsius the initial concentration of the three gases are.3M H 2 S,.3H 2 and .150 S 2 you just need to determine the equilibrium concentrations of all these given 3 gases?
the approximate equivalence point of a ph meter titration before before carrying out the ph titration
If you start with 5.0mL of isopentyl alcohol and after esterification via glacial acetic acid you obtain 6.2mL of isopentyl acetate
When the liberated hydrogen gas is collected over water at 29 degrees celsius and 752 torr, the volume is found to be 343 mL. The vapor pressure of water at 29 degrees celsius is 30.0 torr. What is the mass percentage of aluminum in this alloy?
