5 Mol Na, 5 mol Br2 and 2.3 mol Na, 1.9 mol Br2

2.5 mol Na, 1 mol Br2 and 11.8 mol Na, 6.9 mol Br2

Answer 1

The answer is

reaction of Na and and Br. i 2 NaBr (s) S0 200g)+ Br2 (7) ► 2 mal with I rool Br og rol Na reacts to form NaBr. Now, 5 mol .Na reacts with 12 1/2 x 5 mol ar to form 5 But here 2.5 mil Brz molt Na Bri 5 mol Br, is ginen. here readgent is limiting so, 5 mol Br2 5 Nals + 5 Boz (5) 5 NaBr (s) 2 2.3 mol Na will react with a 2.3 ar arolar to form, here 2.3 mol 2 2.15 mol Bn NaBr but 1.9 rool Br2 is given. 2:3 Na(s) + 1.9 Brg (8) 2.3 na Br(s) Lohitimu 3 2.5 mol Na react with = 215 2 rol Brz 21.25. sro, Br but here I mol Br2 is given so, here limiling reagent it Bra r911 CS Scanned with CamScanner She

so from, al rol Bre, raBr formed a2mu) 2.5 mol Na oina equation! imol Br 2.5 ra(s) + 1 Brz (9) 2rabro ( S 4 11.8 wa mili react with a 11.8 2 mol BR but here mol Brz 25.9 mol Bry is given Na Br formed 2 zili 8 mol. equation! - 11.8 Nals). + 6.9 Brz (9) +6.9 Br2 (8) ► 11.8 irabelo) CSScanned with CamScanner
