Indicate whether each of the following describes the oxidizing agent or the reducing agent in an oxidation-reduction reaction: a)the substance that is reduced. b)the substance that loses electrons.
In another experiment it was determined that for each mole of hydrocarbon, 7 moles of oxygen gas are consumed and 5 moles of CO2 gas and 3 moles of H2O liquid are produced. Find ?H per mole of this hydrocarbon (in kJ) at 298 K
Do the same to show the formation of both elimination products from 2-bromo-2methylbutane (page 208 lists the two products as 2-methyl-1-butene and 2-methyl-2-butene.)
The melting of ice requires 1.44 Kcal/mol. If this energy goes into breaking H-bonds, how many H-bonds will there be in liquid water at 0°C?
How many grams of lanthanum chloride LaCl3 must be added to 1 kg of water to lower the freezing point of water by 1.1 degrees C?
how much energy is required to warm 100g of H2O from 20 degrees celcius to 80 degrees celcius if it is initially in a 140g glass flask? the specific heat of water is 4.18 J/g degree celcius.
A sample of pure (1 chloroethyl) benzene had a specific rotation of 87.2 degrees, while pure R 1 chloro-1-phenyl ethane has a specific rotation of -109 degrees. This sample was reacted with excess ammonia in diethyl ether at 0 c.
seperate two compounds efficiently, what alternatives would one consider to effect clean separation by distillation?
Determine the equilibrium concentrations - what are the new equilibrium concentrations of all species.
Which of the intermolecular forces is the most important contributor to the high surface tension shown by water and What is the quantum of light called?
Calcultate what is the value of enthalpy H reaction If the temperature increased from 35.0 degree celsius to 76 degree celsius and the heat capacity of the calorimeter = 23.3kj/c ? (the molar mass of C2H5OH = 46.07g/mol. )
The syringe used in this experiment is calibrated to 60 mL. However, there is a 'dead volume' at the needle end of the syringe that is uncalibrated. This volume equals 1.20 mL. Bearing in mind that the syringe is upside down
NaOH was added. Assuming no volume change, calculate the pH of the solution
