Answer #1

4NH3+ 5O2 --> 4NO + 6H20
a. How many grams of O2 are needed to react completely with 5.5
g of NH3?
b. How many grams of H2O are produced from 5.44g O2?

C2H6(g) + O2(g) -->
CO2(g) + H2O(g)
(a) Consider the unbalanced equation above. How many grams of
O2 are required to react with 15.0 g of
C2H6? Use at least as many significant
figures in your molar masses as in the data given
g O2
(b) What mass of CO2 is produced?
g CO2
(c) What mass of H2O is produced?
g H2O

How many grams of carbon dioxide are formed if 0.164 moles of
ethanol (CH3CH2OH) react with 80 grams of
oxygen according to the following balanced equation:
CH3CH2OH (l) + 3 O2 (g) → 2
CO2 (g) + 3 H2O (l)

Balance the equation
H2S(g)+O2(g)=SO2(g)+H2O(g)
1. how many grams of oxygen are required to react with
2.30 g dihydrogen sulfide?
2. how many grams of sulfur dioxide. an be produced
when 38.9 g oxygen react?
3. how many grams of oxygen are required to produce
55.4 g water vapor?

3. Given the following reaction: 2C2H6(l) +
7 O2(g) ---- 4CO2(g) +
6H2O(l)
How many moles of O2 is needed to produce 5.00 g H2O?
If 8.32 g of ethane react, how many grams of carbon dioxide will
be formed? How many grams of water will be produced?

Consider the following reaction:
4 NH3 + 5O2 ->
4NO + 6 H2O
How many moles of O2 are needed to react with 4.2 mol
NH3?
How many moles of H2O can be produced from 1.34 mol
O2?
How many grams of NH3 will react with 43.4 g
O2?
How many grams of O2 are needed to produce 56 g
NO?

How many mL of 0.565 M HCL are needed to react with
79.2 g of CaCO3?
2HCl+ CaCO3 ---> CaCl2+CO2+ H2O

2 C2H2 (g) + 5
O2 (g) à 4 CO2 (g) + 2 H2O (g)
How many moles of O2 are needed to react with 15.0 mL of C2H2 at
125oC and 1.25 atm? Please show work!

How many moles of carbon dioxide, CO2, are produced if 5.87
moles of glucose, C6H12O6, react?
C6H12O6(s) + 6 O2(g) → 6 CO2(g) + 6
H2O(l)

2C4H10+13O2 -----> 8
CO2+10 H2O
If there is excess C4H10 how many grams of
O2 are needed to produce 144 rams of CO2. (
