types of reactions
Compounds break down into elements.
What is decomposition?
Balance:
LiCl = Li + Cl2
2LiCl = 2Li + Cl2
Li = 1 > 2 Li = 1 > 2
Cl = 1 > 2 Cl = 2
Balance:
Al + HCl = H2 + AlCl3
2Al + 6HCl = 3H2 + 2AlCl3
Al = 1 > 2 Al = 1 > 2
H = 1 > 6 H = 2 > 6
Cl = 1 > 6 Cl = 3 > 6
Balance:
NH3 + O2 = N2 + H2O
4NH3 + 3O2 = 2N2 + 6H2O
Is this balanced?
H2O + SO3 = H2SO4
YES! 🎀
Elements build into compounds?
What is synthesis?
Balance:
CH4 + O2 = CO2 + H2O
CH4 + 2O2 = CO2 + 2H2O
C = 1 C = 1
H = 4 H = 2 > 4
O = 2 > 4 O = 3 > 4
Balance:
SO2 + H2 = S + H2O
SO2 + 2H2 = S + 2H2O
S = 1 S = 1
O = 2 O = 1 > 2
H = 2 > 4 H = 2 > 4
Balance:
CO2 + H2O = C2H5OH + O2
CO2 + 3H2O = 2C2H5OH + 3O2
Is this balanced?
C2H4O2 + O2 = 2CO2 + 2H2O
NO!🪠
Requires Oxygen and results in CO2 and H2O.
What is combustion?
Balance:
P4 + O2 = P2O3
P4 + 3O2 = 2P2O3
P = 4 P = 2 > 4
O = 2 > 6 O = 3 > 6
Balance:
CH4 + S = CS2 + H2S
CH4 + 4S = CS2 + 2H2S
C = 1 C = 1
H = 4 H = 2 > 4
S = 1 > 4 S = 3 > 4
Balance:
CO2 + H2O = C2H6 + O2
4CO2 + 6H2O = 2C2H6 + 7O2
Is this balanced?
S8 + 11O2 + 2SO2
NO!🚑
XY + A = AY + X
What type of reaction is this? ^
What is an example of single displacement?
LiCl = Li + Cl2
Li = 1 > 2 Li = 1 > 2
Cl = 1 > 2 Cl = 2
Balance:
CH4 + H2O = H2 + CO
CH4 + H2O = 3H2 + CO
C = 1 C = 1
H = 6 H = 2 > 6
O = 1 O = 1
Balance:
C3H8 + O2 = CO2 + H2O
C3H8 + 5O2 = 3CO2 + 4H2O
Is this balanced?
ZnSO4 + Li2CO3 = ZnCO3 + Li2SO4
YES!🏋️♀️
AgNO3 + KCl = KNO3 + AgCl
^This is an example of what type of reaction?
Double displacement.
🪅DAILY DOUBLE🪩
Balance:
Al2O3 = Al + O2
Al = 2 > 4 Al = 1 > 4
O = 3 > 6 O = 2 > 6
Balance:
CS2 + O2 = CO2 + SO2
CS2 + 3O2 = CO2 + 2SO2
C = 1 C = 1
S = 2 S = 1 > 2
O = 2 > 6 O = 4 > 6
Balance:
N2 + H2O = NH3 + NO
