Video transcript

Hey everyone, this question states that the law of conservation of mass is the guiding principle when balancing reaction equations. Is this statement true or false? So let's think about this real quick. The law of conservation of mass states that atoms are neither created nor destroyed. And if this is the case, then that means mass is conserved during our chemical reactions and our reactions are balanced because of that conservation of mass. So this statement is going to be true. So I hope this made sense and let us know if you have any questions.

Textbook Question

A key step in balancing chemical equations is correctly identifying the formulas of the reactants and products. For example, consider the reaction between calcium oxide, CaO(s), and H2O1l2 to form aqueous calcium hydroxide. (b) Is it possible to balance the equation if you incorrectly identify the product as CaOH1aq2, and if so, what is the equation?
