False. According to the Law of Conservation of Mass, chemical equations must be balanced. This means that the number of atoms of each element must be the same on both sides of the equation.
False. According to the Law of Conservation of Mass, chemical equations must be balanced. The number of atoms of each element on the left-hand side of the equation must be equal to the number of atoms of the same element on the right-hand side of the equation. In order to balance a chemical equation, you need to adjust the coefficients (the numbers in front of the chemical formulas) until the equation is balanced. This can be done by adding or changing the coefficients while making sure that the same number of atoms of each element are present on both sides of the equation.
