First, state the balanced equation that represents the combustion:

CH4 + 2O2 → CO2 + 2H2O

Second, state the molar ratios: 1 mol CH4 : 1 mol CO2.

Third, given that at constant temperature and pressure, the volume of an ideal gas is proportinal to the number of moles, you can state the volumetric proportion:

1 Liter of CH4 : 1 Liter of CO2.

Fourth, use the volumetric proportion:

2.0 Liter CH4 * 1 Liter CO2 /1 Liter CH4 = 2.0 Liter CO2.

Answer: 2.0 Liter CO2.

How many moles of nitrogen trifluoride (NF3) can be produced from 9.65 mole of Fluorine gas (F2)
user100 [1]

Answer:

6.43 moles of NF₃.

Explanation:

The balanced equation for the reaction is given below:

N₂ + 3F₂ —> 2NF₃

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of NF₃.

Finally, we shall determine the number of mole of nitrogen trifluoride (NF₃) produced by the reaction of 9.65 moles of Fluorine gas (F₂). This can be obtained as follow:

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of NF₃.

Therefore, 9.65 moles of F₂ will react to to produce = (9.65 × 2)/3 = 6.43 moles of NF₃.

Thus, 6.43 moles of NF₃ were obtained from the reaction.
