<span>Scientists consistently link two catastrophic events with the five major mass extinctions recorded throughout Earth's history. These two events are A) global ice ages and the impact of asteroids. Global ice ages led to the extinction of many populations over time, whereas when asteroids hit Earth, dinosaurs disappeared, among other species. </span>
The Law of Conservation of Mass is defined and explained using examples of reacting mass calculations using the law are fully explained with worked out examples using the balanced symbol equation. The method involves reacting masses deduced from the balanced symbol equation.
