Balancing Chemical Equations
H2O --> H2 + O2
Is this equation balanced?
Nope! There is ONE oxygen on the left, but TWO on the right.
What kind of reaction is this?
2H2 + 1O2 → 2H2O
Synthesis
Which will conduct electricity?
a. acids
b. bases
c. both
C!
H2CO3-->H2O+CO2
How many Oxygen atoms are on the RIGHT side of this equation?
3 (One in H2O + Two in CO2)
What kind of reaction is this?
__H2O2 → __H2O + __O2
Decomposition
What is the MAXIMUM pH value?
14
__Cu + __H2O + __O2 → __Cu(OH)2
How many oxygens are on the left and right in this equation? (Hint: it's not balanced!)
3 on the left, 2 on the right
What kind of reaction is this?
___ C3H8 + __O2 → ___CO2 + ___H2O
Combustion
A substance is sticky and sour. Is it an acid or a base?
Acid
DAILY DOUBLE!!
__Zn + __HCl → __ZnCl2 + __H2
What numbers should go in the blanks?
1, 2, 1, 1
What kind of reaction is this?
__KBr + __F2 → ___ KF + ___Br2
Single Replacement
Positive charges travel:
a. From acids to bases
b. From bases to acids
A! Bases are "hungry" for positive charges, while acids want to get rid of theirs.
