Which of the following statements about balanced equation is false? In a balanced reaction:
Group of answer choices
net charge must be balanced on both sides of the reaction arrow
atoms must be balanced on both sides of the reaction arrow
molecules must be balanced on both sides of the reaction arrow
mass must be conserved
A, B and D are correct.
Thanks!
The false statement about a balanced equation is: "net charge must be balanced on both sides of the reaction arrow."
To determine which of the statements about a balanced equation is false, let's examine each statement:
Statement 1: Net charge must be balanced on both sides of the reaction arrow.
This statement is true. In a balanced equation, the total charge of the reactants must be equal to the total charge of the products.
Statement 2: Atoms must be balanced on both sides of the reaction arrow.
This statement is true. Balancing an equation involves ensuring that the number of atoms of each element is the same on both sides of the equation.
Statement 3: Molecules must be balanced on both sides of the reaction arrow.
This statement is true. Balancing an equation requires ensuring that the same number of molecules is present on both sides of the equation.
Statement 4: Mass must be conserved.
This statement is also true. The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction. Balancing an equation ensures that the total mass of the reactants is equal to the total mass of the products.
Therefore, none of the statements are false. All statements about a balanced equation are true.
