Questions & Expertly Verified
Quiz_________________?
Activation Energy -
Answer✅
The amount of energy required to reach the transition state, the highest point on the graph.
At this point, all reactant bonds have been broken, but no product bonds have been formed,
so this is the point in the reaction with the highest energy and lowest stability.
Quiz_________________?
Amorphous Solid -
Answer✅
Solids whose particles have no orderly pattern.
Quiz_________________?
Anode -
Answer✅
Where oxidation occurs and the solution is becoming more positively charged, the negative
anions from the salt bridge solution flow into the half-cell.

atomic number -
Answer✅
The same as the number of protons in the nucleus of an element; it is also the same as the
number of electrons surrounding the nucleus of an element when it is neutrally charged.
Quiz_________________?
Atomic Radius Trends -
Answer✅
Atomic radius decreases across a period
Atomic radius increases down a group
Cations are smaller than their atoms
Ions are larger than their atoms
Quiz_________________?
Aufbau principle -
Answer✅
States that when building up the electron configuration of an atom, electrons are placed in
orbitals, subshells, and shells in order of increasing energy.
Quiz_________________?
Avogadro's number -
2
, Answer✅
6.022×10²³ particles per one mole
Quiz_________________?
Bent Geometry -
Answer✅
- Central atom has four electron pairs
- two lone pair
- sp³ hybridization
- 109.5° bond angle
- Ex. H₂O, OF₂, NH₂⁻
Quiz_________________?
Bent Geometry -
Answer✅
- Central atom with three electron pairs
- One lone pair
- sp² hybridization
- 120° bond angle
3
, - Ex. SO₂
Quiz_________________?
Bond Energy -
Answer✅
The energy required to break a bond.
Because the breaking of a bond is an endothermic process, bond energy is always a positive
number.
When a bond is formed, energy equal to the bond is released.
ΔH° = Bond energies of bonds broken - bond energies of bonds formed
ΔH° = reactants - products
Quiz_________________?
Boyle's Law (If temperature is constant) -
Answer✅
As pressure increases, volume decreases, and vice versa
Quiz_________________?
Buffer Solution -
Answer✅
A solution consisting of a weak acid plus its conjugate base or a weak base plus its conjugate
acid.
