Answer to Question #278142 in General Chemistry for mass

Question

12) Write the word and skeletal chemical equation for each reaction. [4 marks, C] Show states in the chemical equation. 

a) The COMPLETE combustion of butane (C4H10). 

Word: 

Chemical: 

b) The INCOMPLETE combustion of methanol (CH3OH). 

Word: 

Chemical:

Answer 1

A)Word:Butane burns completely in air to produce CO₂ and H₂O

Chemical:

2C₄H₁₀ + 13O₂------- 8CO₂ +10 H₂O

B)Word:The basis for incomplete combustion is that instead of carbon dioxide being produced alongside water, carbon monoxide and carbon is produced instead, the carbon being released as soot. That handily sets the products up for the equation.

Chemical:

3CH₃OH + 2O₂ ---------- 6H₂O + 2C + CO
