Calculate the amount of heat required to raise the temperature of 1500g of water from 25C to 63C
the decomposition of N2O5 in carbon tetrachloride proceeds as follows: 2 N2O5 -> 4 NO2 + O2. The rate law is first order in N2O5. At 64 degree celcius the rate constant is 4.82 x 10^ 3 s ^ -1.
Compute the final temperature of the mixture (assuming no heat loss to the surroundings.)
A steel tank has a volume of 438 L and is filled with 0.885 kg of oxygen. calculate the pressure of oxygen at 69.8 fahrenheit.
For the reaction:2CH4(g) C2H2(g) + 3H2(g) 0.115 mole of CH4 was placed in a 1.00 L container. At equilibrium it was found that the [C2H2] = 0.035 M. What is the value of the equilibrium constant?
Suppose a black-body chamber is constructed from 55.8 g (one mole) of iron and heated to 500 K. Classical theory and the observations of Dulong and Petit indicate that the total energy of vibration of iron atoms is 3RT per mole.
When NH3 is prepared from 28 g N2 and excess H2 the theoretical yield of NH3 is 34 g. When this reaction is carried out in a given experiment, only 30. g is produced.
Synthesizing ethers via acid-catalyzed condensation reactions has limited usefulness. The conditions (sulfuric acid and heat) are also conducive to elimination products. Clarification of Organic Chemistry
Determine the partial pressure and total pressure of the gases and Find the partial pressure of carbon dioxide in a gas mixture
There are two reason why the enols of beta-dicarbonyl compounds, such as pentane-2,4-dione are relatively stable. One is that they are conjugated and the pi-electron overlap due to the conjugation provides additional stability.
How many milliliters of 6 M HNO3 would you add to 300 mL of the buffers solution to change the pH from 5.09 to 5.03?
Determine the numbers of oxygen molecules are required for each molecule of C 6 H 12 O 6 glucose that is oxidized if Glucose is oxidized by molecular O 2 to CO 2 and H 2 O?
Medical technicians use deoxyglucose labeled with fluorine-18 to locate tumors using a pet scan. A medical technician injects a patient with a therapeutic dose of fluorine-18.
