C3H2 + 502 + 3 CO2 + 4H20
nordsb [41]

Answer: 6.2 moles

Explanation:

C3H8(g) + 5O2(g) ---> 3CO2(g) + 4H2O(g)

The balanced equation above shows the combustion of propane, C3H8 in oxygen, O2 to yield carbon dioxide, CO2 and water, H2O

The mole ratio of combustion are as follows:

1 mole of C3H8 react to produce 4 moles of H2O

1.55 mole of C3H8 will react to produce Z moles of H2O

To get the value of Z, cross multiply

Z x 1 mole = 1.55 mole x 4 mole

Z = 6.2 moles

Thus, 6.2 moles of water will be produced from 1.55 moles of propane

For the following equation: 4NH3(g) + 7O2(g) ® 4NO2(g) + 6H2O(g), how many moles of ammonia (NH3) will be required to produce 10
Mariulka [41]

Answer:

6.67 moles of NH₃

Explanation:

From the equation of reaction,

4NH₃(g) + 7O₂(g) → 4NO₂(g) + 6H₂O(g),

4 moles of NH₃ will produce 6 moles of 6H₂O,

X moles of NH₃ will produce 10 moles of H₂O

X = (10 * 4) / 6

X = 6.67 moles of NH₃

6.67 moles of NH₃ will produce 10 moles of H₂O
