Methanol, ch, oh (mm = 32.05 g/mol), is prepared industrially from this gas-phase reaction:
co(g) + 2h2(g) - ch2oh()
in a laboratory test, a reaction vessel was filled with 63.4 g co (mm = 28.01 g/mol) and 97.2 g of hz.
how many grams of methanol would be produced in a complete reaction? which reactant remains left
over at the end of the reaction? how many grams of it remain?

Hydrogen will left.

Mass of hydrogen left = 88 g            

Mass of methane produced = 73.72 g

Explanation:

Given data:

Molar mass of methanol = 32.05 g/mol

Mass of carbon monoxide = 63.4 g

Molar mass of carbon monoxide = 28.01 g/mol

Mass of hydrogen gas = 97.2 g

Molar mass of hydrogen gas = 2 g/mol

Mass of  methanol = ?

Excess reactant = ?

Amount of excess reactant left = ?

Solution:

Chemical equation:

CO(g) + 2H₂(g)   → CH₃OH(g)

Number of moles of CO

Number of moles = mass/ molar mass

Number of moles = 63.4 g/ 28.01 g/mol

Number of moles = 2.3 mol

Number of moles of H₂:

Number of moles = mass/ molar mass

Number of moles = 97.2 g/ 2 g/mol

Number of moles = 48.6  mol

Now we compare the moles of methane with hydrogen and carbon monoxide gas through balanced chemical equation.

                       CO     :     CH₃OH

                        1        :          1

                        2.3    :        2.3

                      H₂        :        CH₃OH

                        2        :            1

                       48.6    :            1/2×48.6 = 24.45 mol

Number of moles of methane produced by CO are less so it will limiting reactant.

Mass of methane = moles × molar mass

Mass of methane = 2.3 mol × 32.05 g/mol

Mass of methane = 73.72 g

The hydrogen gas is in excess amount. Some of its amount will remain at the end of reaction unreacted.

Amount of hydrogen remain unreacted:

                              CO          :        H₂

                                1            :         2

                               2.3         :         2×2.3 = 4.6 mole

so 4.6 moles of H₂ react with 2.3 moles of CO.

Total number of moles of hydrogen = 48.6 mole

Number of moles left = 48.6 - 4.6 = 44 moles

Mass of hydrogen left = moles  × molar mass

Mass of hydrogen left = 44 mol  × 2g/mol

Mass of hydrogen left = 88 g            

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

its going to be mutualism cuz they both benefit from the relationship.
