H2SO4 reacts with NaOH, producing water and sodium sulfate. What volume of 2.0 M H2SO4 will be required to react completely with 75 mL of 0.50 mol/L NaOH? show your work

H²SO⁴ + 2NaOH → Na²SO⁴ + 2H²O

No. of moles of NaOH = 0.50×75÷1000 = 0.0375mol

2mol of NaOH reacted with 1 mol of H²SO⁴.

No. of moles of H²SO⁴ needed to react with 0.0375mol of NaOH

= 0.0375×1÷2

= 0.01875mol

Vol. of H²SO⁴ = 0.01875×1000÷2.0 = 9.375mL

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.
