A. write an equation for determining the number of moles of naoh that are added to the flask based on [naoh] and volume of naoh titrant (ml naoh): b. write a similar expression for the number of moles of h2so4 in the flask based on [h2so4] and the volume of h2so4 (ml). substitute your expressions from a and b into this equation and solve for [h2so4]

The concentration of [H2SO4] is obtained from; [NaOH] × VNaOH/ 2× VH2SO4

The equation of the reaction is;

2NaOH(aq) + H2SO4(aq) >  Na2SO4(aq) + 2H2O(l)

Number of moles of H2SO4(nH2SO4) = [H2SO4] × VH2SO4

Number of moles of NaOH(nNaOH) = [NaOH] × VNaOH

Where;

[H2SO4] = concentration of H2SO4

VH2SO4 = volume of H2SO4

[NaOH]  = concentration of NaOH

VNaOH = volume of NaOH

From the balanced reaction equation;

2 moles of NaOH reacts with 1 mole of H2SO4

2nH2SO4 = nNaOH

2[H2SO4] × VH2SO4 =  [NaOH] × VNaOH

[H2SO4] =   [NaOH] × VNaOH/ 2× VH2SO4

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
