Calculate the number of pounds of CO2 released into the atmosphere when a 18.0-gallon tank of gasoline is burned in an automobile engine. Assume that gasoline is primarily octane, C8H18, and that the density of gasoline is 0.692 g·mL-1 (this assumption ignores additives). Also assume complete combustion
What weight of A would be removed from a solution of 21 g of A in 50 mL of water by a single extraction
If only 10ml of 3.0 M KOH were used in the alum preparation instead of the specified 25 ml,would KOH then become the limiting reactant? Write the chemical equation for the conversion of Al(s) to solid aluminum alum KAL(SO4)2*12H2O (S)
Organic hydrogenation reactions, in which H2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries.
calculate the E cell when [Zn^+2] = 0.10M and [Cu^+2] = 2.0 x10^-4M. Is the reaction Spontaneous or Non- spontaneous?
Energy cost of dissociation was found to be 4 kWh/m3 of CO2. Calculate conversion degree of CO2 into CO and O2 in this system.
What is the pH at the stoichiometric point? What is the pH when 105% of the base required to reach the stoichiometric point has been added?
How much 10.0 M HNO3 must be added to 1.00L of a buffer that is 0.001 M acetic acid and 0.1 M sodium acetate to reduce the pH 5.45? (pKa of acetic acid = 4.75)
If 5.0 g of H2 are reacted with excess CO, how many grams of CH3OH are produced, based on a yield of 86%? CO(g) + 2H2(g) -> CH3OH(l)
When the two substances reach thermal equilibrium, the final temperature is 24.2 degrees celcius. What is the mass of the copper block?
For a chemical reaction to be non-spontaneous at any temperature, which of the following conditions must be met
What is the concentration of OH- in a solution that contains 0.225g of NaOH in 0.250L of solutio.
If you fill the larger tank with oxygen to a pressure of 155 atm, to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases.
