You will be introduced to a chemical reaction and asked to investigate what happens when a solid is heated and the resulting chemical reaction occurs.
After completing this tutorial, you will be able to complete the following:
When a chemical reaction occurs, a substance is transformed into a new substance or substances. To represent this, chemical equations are written that include elements and compounds. These equations need to be balanced. Therefore, when chemical equations are written, the mass of the reactants need to be equal to the mass of the products. Coefficients are used to ensure that the total number of atoms for each element is equal to the reactants and the products in the reaction. Equations are balanced in order to uphold the law of conservation of mass, which states that mass cannot be created or destroyed.
