False. The molecules of liquid are hold in the liquid state due to intermolecular forces or Van de Waals forces , without affecting the molecule itself and its atomic bonds (covalent bonds). When the temperature increases the kinetic energy of the molecules is higher , therefore they have more possibilities to escape from the attractive intermolecular forces and go to the gas state.
Note however that this is caused because the intermolecular forces are really weak compared to covalent bonds, therefore is easier to break the first one first and go to the gas state before any covalent bond breaks ( if it happens).
A temperature increase can increase vaporisation rate if any reaction is triggered that decomposes the liquid into more volatile compounds , but nevertheless, this effect is generally insignificant compared with the effect that temperature has in vaporisation due to Van der Waals forces.
At STP (standard temperature and pressure conditions), 1 mol of any gas occupies 22.4 L This rule is applied to O₂ 22.4 L volume occupied by 1 mol Therefore 83.4 L occupied by - 1/ 22.4 x 83.4 = 3.72 mol stoichiometry of O₂ to H₂O is 1:2 then the number of moles of water produced - 3.72 mol x 2= 7.44 mol mass of water produced - 7.44 mol x 18.01 g/mol = 134.1 g correct answer is D
The Moon's surface is dominated by igneous rocks. The lunar highlands are formed of anorthosite, an igneous rock predominantly of calcium-rich plagioclase feldspar
