The reaction equation is: C2H5OH + 3 O2 = 2 CO2 + 3 H2O. 1. Consider the following chemical equations. 4Ag + 4NaCN + O2 + 2H2O = 4AgCN + 4NaOH This program was created with a lot of help from: The book "Parsing Techniques - A Practical Guide" (IMHO, one of the best computer science books ever written.) Select the equations that represent chemical reactions, rather than physical changes I. CH4 (g) + O2 -> CO2 (g) + H2O (g) We also notice that as it now stands we have an odd number of oxygen molecules on the right and an even number on the left, which won't work. Problem: Consider the mixture of ethanol, C2H5OH, and O2 shown in the accompanying diagram.How many molecules of CO2, H2O, C2H5OH, and O2 will be present if the reaction goes to completion? We’ve discounted annual subscriptions by 50% for COVID-19 relief—Join Now! Now count the number of oxygen on the product side and you get seven.  One oxygen came from the ethanol so you need 6 more from oxygen. chemistry.
