the heat change value that you calculate from your experiments will be for the amount of material that you use in each reaction. how will you convert it to kJ/mol?
the heat capacity for the heat capacity of the calorimeter in calculating the enthalpy of reaction. What effect would ignoring this have on the calculation?
Chemistry: Change in Temperature in the Production of Silver Chloride, When solutions containing silver ions and chloride ions are mixed, silver chloride precipitates:
What mass of Al2O3 in grams can be made by reaacting 4.6 g AL with excess oxygen?
what are the hydrolysis by-products? What limits the reaction? What determines whether the hydrolysis reaction proceeds from cellulose to sugar (e.g. glucose) or continues on to convert the sugars to alcohol?
Calculate the five points indicated in the experiment introduction and show these values in a small table along with one sample calculation.
Pyruvic acid, HC3H3O3, is involved in cell metabolism. It can be assayed for (that is, the amount of it determined) by using a yeast enzyme. The enzyme makes the following reaction go to completion.
The vapor pressure of dichloromethane,CH2Cl2, at 0 C is 134 mmHg. The normal boiling point of dichloromethane is 40 C. Calculate its molar heat of vaporization.
when the explosion destroys the bomb casing the gas is released into the atmosphere where it reaches a pressure of 1.00 atm. what is the volume of the gas after the explosion? assume constant temperature and number of moles.
Calculate the percentage of He atoms at 100oC which have speeds in the range between 1200 m/s and 1300 m/s. Calculate the percentage of these He atoms that have speeds greater than 5000 m/s
List and describe briefly the 2 methods which are used by drug companies to discover lead compounds
A feed stream containing 2.00 mol/min of butane (C4H10), and a feed stream containing 130.0 mol/min of air are fed into a reactor. The butane combusts completely according to the following reaction.
