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
A chemical reaction to occur, reactant particles must collide with sufficient energy and the correct orientation
What is collision theory?
R-CHO
What is an aldehyde?
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)?
The reducing agent for the equation:
I₂ + SO₃²⁻ + H₂O → 2I⁻ + SO₄²⁻ + 2H⁺
What is SO32-?
The change in enthalpy when one mole of a compound is formed from its constituent elements in their standard states
What is the enthalpy of formation?
For gaseous systems, increasing pressure shifts equilibrium toward the side with fewer of these.What are moles of gas?
What are moles of gas?
The steps for free radical substitution?
What is initiation, propagation, and termination?
The conjugate acid to HNO3 in the reaction: HNO3 + H2SO4 => H2NO3+ +HSO4-
What is H2NO3+?
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/backwards)?
CH₃COOCH₃
Methyl ethanoate
[OH-] = 10-4
What is pH of 10?
