Lecture 4 - Balancing Reactions

Expression- terms separated by operation

Equation- terms separated by equal sign (or arrow sign in chem; due to law of conservation of mass)

Chemical Equation

reaction with o2 to produce new product

Combustion

1. Redox reaction

2. Nuclear reaction

Lahat to sa list ay redox reaction ang tawag kasi may transfer of e^-

Types of Reactions (2)

Mag start ang balance pinaka kaunting terms

Last dapat si O2 kasi electron carrier sya, kaya present din sya sa lahat ng term

Disregard NaCl, sinasabi lang wala na iba Na kaya minus 0 sya

Balancing step 1

Balancing step 2

Balancing step 3

Balanced na si Oxygen

Balancing step 4

Final answer

Step 1

Step 2

Step 3

Final answer
