Which phase changes absorb energy
Which release energy
How do we know the difference
Melting, vaporization, sublimation all absorb energy ( The phase has more energy after the change)
Deposition, freezing, condensing all release energy ( Less energy in the system after phase change)
When heating or cooling a substance , the temperature will not change while a substance…..
Is under going a phase change
What happens to the shape and volume of helium gas when it’s transferred from a tank to a balloon
Both shape and volume change
What do the First & Second Plateau on a heating curve represent?
First: Solid to Liquid & vice versa
Melting / Freezing
Second: Liquid to Gas & vice versa
Boiling / Condensation
A substance will ______ at the same temperature.
Melt & boil
Condense & boil
Freeze & sublime
Freeze & condense
Condense & boil
A ________ reaction is a type of reaction where an acid and a base react to form a salt and water
Neutralization
A ____ is typically defined as an ionic compound that includes any cation except H+ and any anion except OH-
Salt
Bronsted-Lowry acid =
Bronsted-Lowry base =
Protons H+ donor
Proton H+ acceptor
Conjugate base is the product formed when….
Conjugate acid is the product formed when…
Conjugate base = product formed when acid loses H+
Conjugate acid = product formed when base gains H+
To find a conjugate Acid from a Base:
Add 1 H+
This mean add one H & a “+” charge
Find the Conjugate Acid from the Base
OH -
HOH or H²0
Find the Conjugate Acid from the Base
NH³
NH⁴+
Find the Conjugate Acid from the Base
HCO ³ -
H²CO³
Find the Conjugate Acid from the Base
C²H⁵COO‐
C²H⁵COOH
To find the Conjugate Base from an Acid
Remove 1 H+ from the acid
