given the law of conservation of mass, we now know that the mass of the reactants must equal the mass of the product.
A balanced chemical equation is when both the products and the reactants are balanced, or have the same number of atoms on each side of the equation. For example: 2H20 --> 2H2 + O2 This means there are 2 water molecules as the reactants (before reaction) and 4 hydrogen and 2 oxygen atoms as the products (after reaction). Technically the equation wouldn't work in real life if it weren't correctly balanced.
A chemical equation can be interpreted in terms of molecular, ionic, or net ionic equations. In a molecular equation, all reactants and products are written as complete compounds. In an ionic equation, all soluble compounds are dissociated into their respective ions. In a net ionic equation, spectator ions are omitted to show only the species that participate in the chemical reaction.
H2O represents the chemical formula for water, which is a chemical compound. In terms of type of equation, it is a molecular formula that shows the number and type of atoms present in a molecule of water.
If a form of energy appears on the right side of a chemical equation, it means that energy is being released during the reaction, often in the form of heat. This is indicated by terms like "heat," "ΔH," or "energy" on the product side of the equation.
A conversion factor for a balanced chemical equation is derived by comparing the coefficients of the reactants and products. In terms of moles, this conversion factor allows us to relate the number of moles of one substance to another in a chemical reaction. It is used to convert between the amounts of different substances involved in the reaction.
reactants-----> products
A chemical equation is the representation of a chemical reaction.
combining like terms or subtracting from both sides of the equation.

Yes, the equation K + Br2 = KBr is a balanced chemical equation. For example, 2 K + Br2 = 2 KBr is one and another balance chemical equation is Fe + Cl2 = FeCl3.
Chemical formulas of reactants and products; number of molecules involved in the reaction.
To check a formula for dimensional consistency, analyze the units on both sides of the equation. Ensure that the units on each side match up in terms of length, mass, time, and other relevant dimensions. If the units on both sides are equivalent, the formula is dimensionally consistent.
It means that, by using the right numbers for the variables, you can simplify both sides of the equation and they will become the same number. But that is yourjob. You have to find those correct numbers for the variables. These are the anxwers for the problem.
To combine all like terms on both sides and reduce it to its simplest form
To solve for y in terms of x, divide both sides of the equation by 2: y = x/2.If x=2y then you have already solved for x.
Yes, the point is that if two terms (or sides of the equation) are equal, then they remain equal as long as you add or subtract the same amount, to or from both of them. It's very logical.
