Any chemical equation you write to explain a chemical reaction must show that the mass of the products is equal to the mass of the [...]. | Any chemical equation you write to explain a chemical reaction must show that the mass of the products is equal to the mass of the reactants. |
Balanced Equations: for each type of atom, the number of atoms on the reactant side of the equation must equal the number of atoms on the [...] side. | for each type of atom, the number of atoms on the reactant side of the equation must equal the number of atoms on the product side. |
A balanced equation reflects the law of conservation of [...]. | A balanced equation reflects the law of conservation of mass. |
You can balance a chemical equation by changing the [...] and only the [...]! | You can balance a chemical equation by changing the coefficients and only the coefficients! |
[...] are the numbers to the LEFT of the entire molecule, compound, or atom. | Coefficients are the numbers to the LEFT of the entire molecule, compound, or atom. |
[...] tell you how many of the molecule, compound, or atom there are. | Coefficients tell you how many of the molecule, compound, or atom there are. |
Coefficients do not tell you [...]. | Coefficients do not tell you what the molecules, compounds, or atoms are. |
You can NOT change [...which numbers?...] when balancing an equation. | You can NOT change the numbers in subscript (to the bottom right) when balancing an equation. |
Changing the numbers in subscript changes the [...] of the molecule or compound. Changing them does not [...] the reaction, it creates a new one. | Changing the numbers in subscript changes the identity of the molecule or compound. Changing them does not balance the reaction, it creates a new one. |
The best way to become good at balancing equations is to [...]. | The best way to become good at balancing equations is to practice balancing them. |
