Question

For the following reaction, 4.71 grams of water are mixed with excess sodium. The reaction yields 7.74 grams of sodium hydroxide. sodium(s) + water (1) sodium hydroxide (aq) + hydrogen ( grams What is the theoretical yield of sodium hydroxide? What is the percent yield of sodium hydroxide? 96

Answer 1

The Balenced chemical equation is. - Nea (s) + H₂o cel NaOH(ar) (sodium) + 142 (g) (watan sodium (hydroxide) C hydrogen? stoichiometrically, I not of water reacts with Imos of sodium to produce Inol of Naoh

18 glonos Now, & Molar mass of watas and molar mass of Nooit a of Naota 40 simol.

water Nel no (IX 18 = 18 g of reacts with excess sodicam to produce cix 40) 240 g of Naoh. Hence of water when reacts with excess sodium then produces 40 2 10.47 g of Naott.. 4.71 g x 4.71 18

So theoretical yield of sodium hydroxide 10.47 grams, Percentage of gield of sodium hydroxide Actual yield of Naoh x 100. Theoretical yld ld of Nooh 2 7.74 g roo's, 10.47 73.923
