Redox Reactions
The amount of heat energy added when the temperature of 2.0g sample of aluminum increases from 25 degrees celsius to 30 degrees celsius given that the specific heat capacity of aluminum is .90 J/gK
What is 9.0 J
Name of theory which states that, for a chemical reaction to occur, reactant particles must collide with sufficient energy and the correct orientation
What is collision theory?
The homologous series represented by R-CHO
What is an aldehyde?
The products of a neutralization reaction
What are water and a salt?
This device is used to measure heat transfer in a laboratory experiment, often by monitoring temperature changes in water.
What is a calorimeter?
A substance that speeds up a chemical reaction without being consumed or permanently altered in the process.
What is a catalyst?
An alcohol where the carbon bonded to the hydroxyl group is also bonded to two carbons and a hydrogen.
What is a secondary alcohol?
On a pH curve for titrating NaOH with HCl, the equivalence point occurs at this pH.
What is 7?
Where oxidation occurs.
What is the anode?
Breaking chemical bonds is this type of process.
What is endothermic?
This expression, calculated using equilibrium concentrations, remains constant for a given reaction at a specific temperature.
What is the equilibrium constant (Kc)?
How acids are definied in the Bronsted-Lowry Theory
What is the H+ donor?
The reducing agent for the equation:
I₂ + SO₃²⁻ + H₂O → 2I⁻ + SO₄²⁻ + 2H⁺
What is SO32-?
The products of incomplete combustion of a hydrocarbon.
What are carbon monoxide and water? OR
What are carbon and water?
For gaseous systems, increasing pressure shifts equilibrium toward the side with fewer of these.
What are moles of gas?
The steps for free radical substitution?
What are initiation, propagation, and termination?
The conjugate base to HNO3
What is NO3-?
The oxidation numbers of H2SO4 for each atom
What is +1 for H, +6 for S and -2 for O
According to this law, the total enthalpy change for a reaction is independent of the pathway taken.
What is Hess’s Law?
If the temperature is increased in an exothermic reaction at equilibrium, the system will shift in this direction to counteract the change.
What is the reverse direction (left/towards reactants)?
The homologous series to which this compound belongs: CH₃COOCH₃
The pH of a solution in which [OH-] = 10-4
What is 10?
