Question

Consider the unbalanced equation for the combustion of hexane: aC6H11 (9) + 302(g) + CO2(g) + SH2O(g) Part A Balance the equation. Give your answer as an ordered set of numbers a, 8, 7,... Use the least possible integers for the O AO ? a, B. 7. 8 = Submit Request Answer Part B Determine how many moles of O2 are required to react completely with 6.3 mol CH14- Express your answer using two significant figures. AED EME? n = mol Submit Request Answer

Answer 1

Balanced Reaction:- сен + 15 °, 6CD, -+ +ң, о 12 + 14н, о 2 2 с.

3). 2 Fecs) +2HBriaal Fe Bracaq) + Hzeg) Mass Fe =3.0 g 아 of Mole Fe mol 3 55.84 = 0.0537 Since, react with 1 mol of fe 2 mol of HBr the 0.0537 mal of te react with 2 ×0.0537mall of WBr ΜαςS of КQх male x molar mass = 0.1074 80.91 8.6937 g So, mass of HBr = 8.69 g 2. Since, 1 mole of Fe give 1 mol of H₂ on reaction 11 so, 0.0537 mot 1 x 0.0537 mol of Hy so, mass moe x molar mass I - 0.053 7 X2 - 0.1074g Yo mode so, ma 0.11 g
