Generally just simple math and the fact that the product has to equal the reactant (except maybe in nuclear reactions)
Ex
_C6H12O6 + _O2 -> _CO2 + _H2O
1. Find the reactant molecule that is the only source of certain atoms in the products:
- Glucose (only source of carbon and hydrogen)
x O2 is not the only source of oxygen glucose has oxygen as well
2. Place a 1 in front of it
1C6H12O6 + _O2 -> _CO2 + _H2O
Now 1 glucose means that there are 6 Carbons and 12 Hydrogens
6 Carbons means that there are 6 carbon dioxides, 6CO2
12 Hydrogens means that there are 6 waters (6*2=12) , 6H2O
1C6H12O6 + _O2 -> 6CO2 + 6H2O
6 CO2 and 6H2O = 18 Oxygens
6 Oxygens are already in glucse
12 Oxygen remaining --> 6O2
1C6H12O6 + 6O2 -> 6CO2 + 6H2O
----------------------------------------------------------------------------
Sometimes this method will give you fractions
_N2 + _H2 -> _NH3
_N2 + 1H2 -> _NH3
1H2 (2 Hydrogens) --> (2/3) NH3 (2Hydrogens)
Multiply both by the denominator
3H2 (6 Hydrogens) --> 2NH3 (6Hydrogens)
2NH3 --> 1N2
1N2 + 3H2 -> 2NH3

What coefficient is needed to balance the reaction?
To balance a chemical reaction, coefficients are adjusted to make the number of atoms of each element the same on both sides of the reaction. The coefficient to balance a reaction depends on the specific reaction being considered.
When a chemical reaction is balanced what number appears?
You think probable to the number of molecules or atoms.
What is needed to balance the reaction Cl2 plus Kl KCl plus l2?
The reaction is already balanced as it is written: Cl₂ + 2Kl → 2KCl + Cl₂. Each side of the reaction has the same number of atoms for each element.
What is needed to balance the reaction Cl2 plus KlKCl plus L2?
To balance the reaction Cl2 + 2Kl -> 2KCl + L2, you need to adjust the coefficients for each compound so that the number of each type of atom is the same on both sides of the reaction arrow. By changing the coefficient of KI to 2, the number of K and I atoms are balanced, and the reaction is balanced as a result.
How to balance a chemical reaction effectively?
To balance a chemical reaction effectively, you need to ensure that the number of atoms of each element is the same on both sides of the equation. Start by identifying the elements present in the reactants and products. Then, adjust the coefficients in front of the chemical formulas to balance the equation. Remember to only change the coefficients, not the subscripts. Repeat this process until the number of atoms of each element is equal on both sides of the equation.

How can one balance redox reactions in acidic solutions effectively?
To balance redox reactions in acidic solutions effectively, follow these steps: Write the unbalanced equation for the redox reaction. Separate the reaction into half-reactions for oxidation and reduction. Balance the atoms in each half-reaction, excluding oxygen and hydrogen. Balance the oxygen atoms by adding water molecules. Balance the hydrogen atoms by adding H ions. Balance the charges by adding electrons to one or both half-reactions. Ensure that the total charge and number of atoms are balanced in both half-reactions. Multiply each half-reaction by a factor to equalize the number of electrons transferred. Combine the balanced half-reactions to form the overall balanced redox reaction. By following these steps, one can effectively balance redox reactions in acidic solutions.
What coefficient values will balance the reaction shown above 2 2 1 1 1 1 2 1 2 1 2 2?
To balance the reaction, you would need to adjust the coefficients of the reactants and products based on the number of atoms of each element involved. Without the specific details of the reaction provided, I can't give the exact coefficients. Generally, you should ensure that the number of atoms for each element is the same on both sides of the equation. If you can provide the specific reaction, I can help determine the correct coefficients to balance it.
What do the big numbers in a chemical equation mean?
the little number means how many atoms are big number means how many of the whole compound there are
What do you often notice after balance hydrocarbon combustion reaction equation?
After balancing a hydrocarbon combustion reaction equation, you often notice that the number of atoms of each element on the reactant side equals the number of atoms of that element on the product side. The coefficients in the balanced equation represent the ratio of moles of each reactant and product involved in the reaction. The balanced equation also helps in determining the stoichiometry of the reaction and the amount of reactants needed or products formed.
How to balance equations in chemistry for a chemical reaction?
To balance equations in chemistry for a chemical reaction, you need to ensure that the number of atoms of each element is the same on both sides of the equation. This is done by adjusting the coefficients in front of the chemical formulas. Start by balancing the elements that appear in only one compound on each side, then balance the more complex molecules last.
What is unbalanced reaction?
An unbalanced chemical reaction is one where the number of atoms of each element does not match on both the reactant and product sides. This can be corrected by adjusting the coefficients of the compounds involved to ensure that the same number of atoms of each element are present on both sides of the reaction.
What needs to be considered in balancing redox reactions?
Both atoms and charge
