Question

CO₂ + H2O . (pts) Ethanol (C2H60) will undergo combustion in the presence of air. Draw a picture of what it looks like after the reaction occurs. ofte 12ts (=6 H =18

Answer 1

Assumption - reaction goes to completion.

C₂H₅OH + 3 O₂ ---> 2 CO₂ + 3 H₂O

Given - 3 molecules of ethanol

6 molecules of oxygen

We first find the limiting reactant using the molar ratios of products and reactants as shown below. Then we find the number of molecules of each product formed.

The limiting reactant is oxygen here. Please refer to below calculations and picture.

DATE Reaction : C2 H₂ OH + 30₂ ) 200₂ + 3H₂O . After the assuming it reaction ocaus goes to completion. from the reaction equation, we can calculate how many molecules со , и,0 , 0, 0 см, он or are formed when reaction is complete. 3 molecules ethanol 6 molecules of oxygen c o moleculesd Co formed 3 molecules of ethand & a moleculloch com a I molecule of ethand 6 molecules of ₂ x 2 molecules of coz a 4 molecules of coz 3 moleculent az formed - : O₂ is limiting reactant in this reaction. - 4 molecules of coz will be formed. To find molecules of no formed 6 molecules of ₂ x 3 molecules of H₂O = 6 moleculesy 10 - 3 molecules of a To find molecules of 4 molecules y co x Ethanol used I molecule of ethanol 3 moleculls y con = 2 molecules of Ethand us which meas 1 slet

no If the reaction goes to completion as 1 molecule of Elhand 4 molecules & co, JA 6 dauleg И0 O molecules of O₂ ooo co₂ o H2O en C2H5OH.
