What is a balanced chemical equation why should the chemical equation be balanced?

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.


What indicates how much of each reactant will be used up in a reaction?

Why must a chemical reaction be balanced before it can be used in stoichiometry?

Balancing a chemical reaction ensures that the number of atoms of each element is the same on both sides of the equation. This is crucial for stoichiometry calculations as it allows us to accurately determine the relationship between reactants and products based on the balanced equation. Without balancing, the calculations would be incorrect and unreliable.


What are the coefficient in 3Mg N2 - Mg3N2?

a coefficient is the number that falls before the chemical formula.so,in 3Mg N2 - Mg3N2 there are 3 coefficients in that chemical equation. These are present on the reactants side.


What information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction?

The information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction is the number appearing immediately before the formula for the reactant in question in the chemical equation. This number is called a "coefficient".

What symbolic representation of a chemical reaction?

A chemical reaction can be symbolically represented using a chemical equation, where reactants are shown on the left side and products are shown on the right side. The equation includes chemical formulas of the substances involved and indicates the balance of atoms before and after the reaction.

Can the number of moles of a substance be found by looking at a balanced equation?

yes the number of moles is the the number before the substance for example if the equation is balanced and you want to find H2O and it appears like 3H2O in the equation then their are 3 moles of H2O


Are moles conserved in a balanced chemical equations?

Yes, moles are conserved in a balanced chemical equation according to the law of conservation of mass. This means that the total number of moles of each element involved in a chemical reaction remains constant before and after the reaction.
