The equation below shows hydrogen reacting with oxygen to produce water. 2H2 + O2 > 2H2O If 16 mol of oxygen were reacted with excess hydrogen gas, how many moles of water would be produced? a. 4.0 mol b. 8.0 mol c. 16 mol d. 32 mol

d. 32 mol

Explanation:

16 mol O2 * (2 mol H2O/1 Mole O2) = 32 Mole H2O

according to kinetic-molecular theory, the following would not be considered an ideal gas:

a gas at very low volumes, when gas particles are very close together

a gas at very low temperatures, when gas particles have very little kinetic energy a gas

a gas with highly polar molecules that have very strong intermolecular forces

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
