Examine the importance and impact of isomerism in industry –
research case studies in order to consider the formation of different
isomers during manufacture, how their presence may influence the
industrial process, the differences in properties that they might
have, and the possible consequences of ignoring the presence of
Which of the following statements about enthalpy is incorrect?
Enthalpy and internal energy of a system are always identical
enthalpy is a state function
$\Delta H$ is the enthalpy change at constant pressure
Reactions which absorb heat have a positive DH
a) Discuss the therapeutic or chemical effects of isomerism.
Research the drugs thalidomide and ibuprofen, and their
therapeutic effects. Both drugs have optical isomers:
compare the structures and properties of the optical
isomers in each case study.
b) Explain why one of these drugs is only available as a
single optical isomer whilst the other is sold as a racemic
mixture (a 50:50 mixture of both optical isomers).
Consider the following chemical reaction which produces water from its constituent elements:

2 H2 (g) + O2 (g) → 2 H2O (l) ΔH = -571.6 kJ mol-1

If hydrogen and oxygen were mixed and allowed to react under constant pressure conditions, which of the following statements must be true?

Select as many answers as applicable however points will be deducted for incorrect guesses.

Select one or more:
ΔH = q
The temperature of the surroundings would increase
The temperature of the surroundings would decrease
This is an endothermic reaction
How much potassium bromide should be added to perform formalin test?
A coffee-cup (constant pressure) calorimeter is used to carry out the following reaction in an unknown volume of water (where X is a hypothetical metal):

X + 2 H2O → X(OH)2 + H2

In this process, the water temperature rose from 25.0 °C to 37.1 °C. If 0.00579 mol of "X" was consumed during the reaction, and the ΔH of this reaction with respect to the system is -1278 kJ mol-1 , what volume of water (in mL) was present in the calorimeter?

The specific heat of water is 4.184 J g-1 °C-1
To process certain metal ores, reactions with carbon can sometimes generate the pure metal at high temperatures.

Consider the reaction of zinc oxide with carbon:

ZnO + C → Zn + CO ; ΔH = 240 kJ/mol of rxn

How much heat needs to be absorbed by the system (in kJ) to react 3121 g of ZnO with 351 g of C until the reaction is completed?
Who were the two earliest pioneers of the American industrial revoution and what were their respective contributions?
Container "A" holds N2 gas with a mass of 54.6 g and is 4.1 times the volume of container "B" which holds argon (Ar) gas at the exact same temperature and pressure. What is the mass of the Ar (in g) within container "B"?
I am doing an acid/base reaction using butyric acid, calcium hydroxide and calcium oxide. After the reaction is run, we are getting oversize particles. I have tried speeding and slowing the rate of butyric addition. What can I do to lower the particle size of the acid/base reaction?
