What is the connection between the relative gas volumes collected in the two tubes and the relative number of gas molecules in the tubes?

Answer : The hydrogen gas had twice the amount of molecules and was twice the volume of oxygen gas.

Explanation : When water decomposes into its component elements, hydrogen and oxygen, when an electrical current is passed through it. The volume of hydrogen, collected in the right test tube, is twice the volume of oxygen. The electrolysis experiment revealed that the moles of hydrogen gas molecules which evolved after the electrolysis experiment where in the twice volume of oxygen gas as there were two molecules of hydrogen present in the water molecule compared to only one oxygen molecule which was present.

answer: mole of the gas

answer: mole of the gasexplanation:

answer: mole of the gasexplanation: this is because 1 mole of a gas is 22.4dm³, which is use in ideal gas

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
