The thickness of a piece of paper is 0.0036 in. Suppose a certain book has an Avogadro's number of pages; calulate the thickness of the book in light years.
How would you change the reaction conditions of acid-catalyzed esterification to favor ester hydrolysis rather than ester formation
Number these in order of ease of hydrolysis. 1= easiest to hydrolyze 4=hardest to hydrolyze C6H5C(=O)OC66H5 C6H5C(=O)OCl C6H5C TRIPLE BOND N C6H5(=O)NHC6H5
Classify the following room-temperature reactions as homogenous catalysis or heterogeneous catalysis: reaction of carbon monoxide and oxygen in a presence of platinum
Assume that a particular reaction evolves 243 kJ of heat and that 28 kJ of PV work is gained by the system....? 1) What are the values of delta E and delta H for the system? 2) What are the values of delta E and delta H for the surroundings?
a volume of 5.3 L at 127 degrees Celsius, what is the pressure of the gas in atmospheres?
Why don't we observe the deBroglie wavelength of everyday macroscopic objects (such as a moving car or a thrown baseball)? The wavelength is too small relative to the size of macroscopic objects to be observed.
Solutions of chymotrypsin prepared for experimental purposes are stored in a dilute solution of hydrochloric acid as a "preservative." Explain.
The mass percent of sulfur in the product is Blank 1 % (2 dec places). The mass percent of oxygen in the product is Blank 2 % (2 dec places).
How many grams of aluminum metal must react with aqueous sodium hydroxide to produce 7.50 L of hydrogen gas at 12.5 degrees Celsius and 740 torr if the other product is aqueous Na3AlO3. 2 Al (s) + 6 NaOH (aq) ----> 3 H2(g) + 2 Na3AlO3(aq)
calculate the molarity of acetic acid in a vinegar sample knowing that 5.00 ml of vinegar requires 43.50 ml of 0.105 m
calculate the mass of sodium nitrate required to produce 7.00 grams of oxygen according to the following reaction: 2NaNO3 = 2NaNO2 + O2
How much energy in kJ is needed to heat 5.00g of ice from -10.0oC to 30.0oC? The heat of fusion of water is 6.01 kJ/mol and the molar heat capacity is 36.6 J/(oK.mol) for ice and 75.3 J/(oK.mol) for liquid water.
