Gaseous methane (ch4) reacts with gaseous oxygen gas (02) to produce gaseous carbon dioxide (co2) and gaseous water (h20). what is the theoretical yield of carbon dioxide formed from the reaction of 1.28 g of methane and 10.1 g of oxygen gas? be sure your answer has the correct number of significant digits in it. 02

Theoretical yield = 3.51 g

Explanation:

The formula for the calculation of moles is shown below:

For  :-

Mass of  = 1.28 g

Molar mass of  = 16.04 g/mol

The formula for the calculation of moles is shown below:

Thus,

For  :-

Mass of  = 10.1 g

Molar mass of  = 31.998 g/mol

The formula for the calculation of moles is shown below:

Thus,

According to the given reaction:

1 mole of methane gas reacts with 2 moles of oxygen gas

0.0798 mole of methane gas reacts with 2*0.0798 moles of oxygen gas

Moles of oxygen gas = 0.1596 moles

Available moles of oxygen gas = 0.3156 moles

Limiting reagent is the one which is present in small amount. Thus, is limiting reagent.

The formation of the product is governed by the limiting reagent. So,

1 mole of methane gas on reaction produces 1 mole of carbon dioxide.

0.0798 mole of methane gas on reaction produces 0.0798 mole of carbon dioxide.

Mole of carbon dioxide = 0.0798 mole

Molar mass of carbon dioxide = 44.01 g/mol

The formula for the calculation of moles is shown below:

Thus,

Mass of = 3.51 g

Theoretical yield = 3.51 g

-be a crystalline solid

- be soluble in water

-conduct electricity

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
