How do you balanced chemical equation?

Answer 1

if u want to gate Ur answer than u first u have to know about molecular formula and balance it with the number of atoms of the elements

Answer 2

1. Write the unbalanced equation.
   • Chemical formulas of reactants are listed on the lefthand side of the equation.
   • Products are listed on the righthand side of the equation.
   • Reactants and products are separated by putting an arrow between them to show the direction of the reaction. Reactions at equilibrium will have arrows facing both directions.
2. Balance the equation.
   • Apply the Law of Conservation of Mass to get the same number of atoms of every element on each side of the equation. Tip: Start by balancing an element that appears in only one reactant and product.
   • Once one element is balanced, proceed to balance another, and another, until all elements are balanced.
   • Balance chemical formulas by placing coefficients in front of them. Do not add subscripts, because this will change the formulas.
   • Use (g) for gaseous substances.
   • Use (s) for solids.
   • Use (l) for liquids.
   • Use (aq) for species in solution in water.
   • Write the state of matter immediately following the formula of the substance it describes.
3. Indicate the states of matter of the reactants and products.

To balance a chemical equation is to modify at least one part of one side of a chemical equation so that eachchemical is equal on one side to the other.

To put this into perspective look at the unbalanced equation Fe + Cl2 → FeCl3.

If you check both sides and count you should find there's 1Fe on each side but 2Cl on one side and 3 on another. So to make sense, this must be balanced. To balance, you must make the sides equal by identifying what is not equal and making them equal.

So for the Cl2, the LCM of 3 and 2 is 6 so you should add another two Cl2 under. Add one more FeCl3 under.

Fe + Cl2 → FeCl3

Cl2 Cl3

Cl2

However, because 2FeCl3 has iron, there is 2Fe on that side so what you must do to one side has to be done to the other (to make them equal). So you then double the Fe on the other side too.

Fe + Cl2 → FeCl3

Fe Cl2 Cl3

Cl2

Now check both sides to see if they're equal. And you usually will find at this point that they are! So all you have to do is add them up accurately paying attention to numbers; multiplication.

You will arrive at your final answer; in this case it is:

2Fe + 3Cl2 → 2FeCl3

Answer 4

You balance a chemical equation by making sure that you have the same number of atoms of each element on each side of the equation.
