Balancing Chemical Equations Strategies

In this video, Dr. B demonstrates how to balance the chemical equation SiO2 + CaC2. The process involves balancing carbon and oxygen atoms, adjusting calcium oxide, and making final adjustments to ensure all elements are balanced. The key strategy is to leave oxygen balancing until the end. The video provides a step-by-step guide to achieving a balanced equation.

What makes the equation SiO2 + CaC2 challenging to balance?
