100
It is also known as a precipitate
What is solid or (s)
100
(g)
What is a gas
100
NaCl (aq)
What is Na+ (aq) + Cl- (aq)
100
The liquid most aqueous solutions are dissolved into.
What is water
100
NaCl, NaOH, Zn(OH)2
Which are insoluble if any? (It doesn't belong with the others... if one exists.)
What is Zn(OH)2 - all group 1 metal-compounds are soluble in water.
Hydroxide is rarely soluble in water.
100
Balance the following molecular equation:
(15 seconds... 14, 13, 12)
200
It is what does the dissolving.
What is a solvent
200
A whole number in front of an element or molecule
What is a coefficient
200
H2O (l)
What is H2O (l) It doesn't generally break into ions...
But if you said H+ and OH- that would be OK
200
True or False. H2O (l) is an aqueous solution
What is False It's a liquid - not ions
200
solute, solvent, solution, liquid
What is liquid
200
Give the complete ionic equation for the following already balanced equation:
35 seconds... 34, 33
(Order on each side matters not.)
300
A gas or solid that dissolves into a liquid
What is solute
300
What does the "2" in H2O stand for?
What is a subscript telling you how many H atoms in the molecule
300
NH4OH (aq)
What is NH4+ (aq) + OH- (aq)
300
T - F Pb compounds NEVER are soluble in water?
What is false. NO3 (nitrates) are ALWAYS soluble, so Pb(NO3)2 - lead nitrate - is soluble in water.
300
aq, ->, g, l, s,
What is ->
300
Give the net ionic equation for the following complete ionic equation, showing the cancelled ions as well on your white board:
(40 seconds... 39, 38)
So:
400
The ions that do not react in a chemical reaction
What are spectator ions
400
(aq)
What is aqueous
400
H2SO4 (aq)
What is 2H+ (aq) + SO42- (aq)
400
aqueous solution breaks down into these
What are its ions
400
The order of simplifying a chemical equation
What is balancing, total ionic equation, and net ionic equation
400
Determine the complete and net ionic equations for the following balanced equation, showing t he spectator ions as crossed out on each side, and (aq) or (s) where appropriate in the net equation:
(90 seconds... 89, 88, 65, 33...)
Better Net:
500
It better represents a chemical equation by specifically showing what reacted and what was produced.
What is a net ionic equation
500
(l)
What is the a liquid? ("aqueous" is not acceptable.)
500
Mg(OH)2 (aq)
What is Mg2+ (aq) + 2OH- (aq)
500
If all of the reactant and product ions are aqueous, what kind of reaction just took place?
What is none.
