What does the `->` mean in reactions?
Name this acid: HNO3
Nitric Acid
2Na + Cl2 -> 2NaCl
What kind of reaction is this?
Synthesis
Sodium + Chlorine -> Sodium Chloride
write out and balance
2Na + Cl2 --> 2 NaCl
Acid-base reactions always have these in their products. What are they?
Water + salt
What is an aqueous solution?
something dissolved in water
What's the little rhyme when naming acids?!
my rIDE has HYDROlICs
sprITE is deliciOUS
i ATE something ICky
What are the products of a combustion reaction?
Carbon Dioxide and Water
When you are balancing equations, you can only put one type of number. What is the name of the number?
Coefficient
How do you know which product is the gas?
It's the one that's NOT aqueous
What are the 7 diatomic molecules?
Hydrogen
Nitrogen
Oxygen
Chlorine
Fluorine
Bromine
Iodine
Silver nitrate + Potassium chloride →
What the products/precipitate?
Silver Chloride (s) + Potassium Nitrate (aq)
Silver Chloride
What kind of reaction are acid-base and gas evolving reactions?
double displacement/replacement reaction
phosphorus + oxygen → tetraphosphorous decaoxide
Write out the balanced equation
4 P + 5 O2 -> P4O10
T/F: Most gas evolving reactions are acid-base reactions.
True
What are the four different states of matter we use in reactions?
Give their symbol and name
(s) solid
(l) liquid
(g) gas
(aq) aqueous
Sodium nitrate + Potassium chloride ->
Is this a precipitate reaction? Explain
No, both products would dissolve.
acetic acid + lithium hydroxide -> lithium acetate + water
what kind of reaction is this? (2 types)
double displacement/replacement
acid-base
acetic acid + lithium hydroxide -> lithium acetate + water
give the formulas and balance it
HC2H3O2 + LiOH -> LiC2H3O2 + H2O
Zn + HCl→
give the balanced equation and identify the gas
Zn+2HCl→ZnCl2+H2
H2
What is the difference between bronsted-lowry acids/bases vs. Arrhenius acid/bases
Acids are pretty much the same, both give off H+
In Bronsted Lowry, bases pick up H+
In Arrhenius, bases give off OH-
Give me the formulas of the following compounds:
Acetic Acid
Tetraphosphorus Decachloride
Magnesium Sulfide
Lithium Acetate
HC2H3O2
P4Cl10
MgS
LiC2H3O2
What are the 5 different types of reactions
Synthesis
Decomposition
Combustion
Single Replacement/Displacement
Double Replacement/Displacement
___ CH3CH2CH2CH3 + ___ O2 → ___ CO2 + ___ H2O
Balance and tell me which type of reaction this is
2 CH3CH2CH2CH3 + 13 O2 → 8 CO2 + 10 H2O
Combustion
Nitric Acid + Lithium Hydroxide -> ???
identify 3 things:
the products
what kind of reaction (2 types)
precipitate?
water + lithium nitrate
double displacement/replacement & acid-base
There is no precipitate. It's a soluble salt that's formed other than water
