some cookies and milk, you've got to take it out for a nice dinner, maybe sit next to a fire with it, really get to know it you know?

To balance the chemical equation N2 + 3H2 -> 2NH3, a coefficient of 1 is placed in front of N2, a coefficient of 3 before the H2, and a coefficient of 2 in front of NH3.

What indicates how much of each reactant will be used up in a reaction?
the coefficients of a balanced reaction
Why chemical equations need to be balanced according to the law of the conservation of mass?
becasuse atoms are never gained or lost in a chemical reaction
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 is ment by the term coefficient in relation to a chemical reaction?
In a chemical reaction, a coefficient is a number that appears before a chemical formula in a balanced equation, indicating the ratio of reactants and products involved in the reaction. It helps balance the equation by ensuring the conservation of mass and atoms on both sides of the reaction.
A chemical equation that is consistent with the law of conservation of mass?
An example of a chemical equation consistent with the law of conservation of mass is the reaction between methane (CH4) and oxygen (O2) to form carbon dioxide (CO2) and water (H2O): CH4 + 2O2 -> CO2 + 2H2O. In this reaction, the number of atoms of each element is conserved before and after the reaction.
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.
What information in a balanced equation shows how many moles of a reactant are involved in the reaction?
This is the number before a chemical compound.
What information in a balanced chemical equation shows how many moles of a reactant are involed in the reaction?
The coefficients in a balanced chemical equation indicate the mole ratio between reactants and products. This allows us to determine the number of moles of each substance that participate in the reaction based on the stoichiometry of the reaction.
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.

How does a chemical equation show that a chemical reaction has occurred?
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
What is present after a chemical reaction?
That depends on the chemicals present before the chemical reaction and sometimes the conditions under which the chemical reaction occurred.

Are chemical equations balanced by changing the subscripts of the molecules?
No, chemical equations are balanced by adjusting the coefficients in front of the chemical formulas. Changing the subscripts would alter the actual chemical identities of the substances involved.
