Types+of+Chemical+Reactions+-+Combustion+(Pt.2)+&Summary

Welcome to the Chemical Reactions part. My job is helping you review the combustion and summary the 5 reactions. And other four major chemical reaction is responsible by anther topic. Let's start.

**Types of Chemical Reaction - Combustion of Hydrocarbons **

**Vocabulary** ** Hydrocarbon ---** a compound made of C and H. As hydrocarbon invovles in combustion, the reaction will produce carbon dioxide and water. Example: CH 4 (l) + 2 O 2 (g)→ 2 H 2 O(l) + CO 2 (g)
 * Combustion -** it is a kind of rapid and active reaction of a substance with oxygen and organic compunds. Usually, it produces substantial amouts of heat with the help of flame so that the reaction also called buring.

Generally, the combustion of a hydrocarbon has a common euqation: **
 * Combustion is an exothermic reaction that gives off heat to its surroundings.
 * Hydrocarbon + O 2 → CO 2 + H 2 O **

How to make sure a chemical reactions is combustion of hydrocarbons? **Step 1:** Looking for a hydrocarbon reactant
 * Step 2:** Checking the chemical reaction, and the products are CO 2 and H 2 O. （ Hydrocarbon + O 2 → CO 2 + H 2 O )

Special cases: **1**. If the burning reactant is an organic compound includes ** oxygen **, the products do not change. EX: C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O ​ EX: C 4 H 8 S +7O 2 → 4CO 2 + 4H 2 O+SO 2 C3H6OS 2 + 6O 2 → 3CO 2 + 3H 2 O + 2SO 2
 * 2.** If the burning reactant is an organic compound includes ** sulphur **, the proucts will have SO 2(g).

** Summary of Chemical Reactions **
