Moles are used to balance chemical equations because they provide a consistent way to quantify the amount of substances involved in a reaction. Since chemical reactions occur at the atomic and molecular level, using moles allows chemists to relate the mass of reactants and products to their respective numbers of particles. This ensures that the law of conservation of mass is upheld, meaning that the number of atoms of each element remains the same before and after the reaction. Balancing equations with moles helps predict yields and understand reaction stoichiometry.
What else can I help you with?
What is a website to balance chemical equations?
GO to Google.com and type in balancing chemical equations and click the 3rd one. It balances it for you. Just type in the formula. :]
Does the total number of moles reactants necessarily equal the total number of moles of product?
No. Take the microbial hydrogen mechanism as an example:4H2 + CO2 --> CH4 + 2H2O5 moles of reactants on the left converts to 3 moles of products on the right. The total number of moles of each type of atom does balance however.
What steps should be followed to solve problems involving chemical equations that ask for the amount of a product from specific reactants?
Write and balance the chemical equation. Convert the given amount of reactant to moles. Use the stoichiometry of the balanced equation to determine the moles of the product formed. Finally, convert the moles of the product to the desired unit (grams or volume) if necessary.
What do you add to the front of elements or compounds to balance them?
To balance chemical equations, you add coefficients in front of elements or compounds. These coefficients represent the number of molecules or moles of each substance involved in the reaction. By adjusting these numbers, you ensure that the number of atoms for each element is the same on both sides of the equation, thus obeying the law of conservation of mass.
H2O on C2H5MgBr balance equations?
C2H5MgBr + H2 = C2H6 + MgBr2
What does stoichiometry use to relate moles of one molcule to moles of another?
Stoichiometry uses the coefficients of balanced chemical equations to relate moles of one molecule to moles of another. It allows for the conversion of quantities between reactants and products in a chemical reaction.
How do can determine the atomic weight of the elements in the periodic table how do can calculate the atomic weight?
These days you can use a mass spectrometer. But when they started it went to Avogadro's number (that's moles) and gases and balanced equations helped along by very expensive balance scales.
How do you balance equations without having to do it manually?
Automatically. What type of equations.
What does stoichiometry use to relate moles to one molecule to moles of another?
Stoichiometry uses coefficient ratios to relate moles of one molecule to moles of another
Why are coefficient used to balance equations?
Coefficients are used to balance equations because if you change the subscript, than you would change the substance.
What does a coefficient show in science?
In science, a coefficient typically represents the numerical factor in a chemical equation that indicates the number of moles of a substance involved in a reaction. It helps balance chemical equations by ensuring that the conservation of mass is achieved.

What is the number in front of the molecule's symbol?
You may be referring to the number of moles of that particular molecule. One mole is equal to 6.0221415x1023. That is how many atoms there are of that particular molecule or element. EG 2SO2(g) + O2(g) is in equilibruim with 2SO3(g) the 2 in front of SO2 and SO3 indicates that there are 2 moles of that molecule. This is how we can balance equations. Moles are used to find mole ratios, molar mass as well as mass etc.
Why is it essential to use balance equations in solving stoichiometric problems?
It is essential to use balanced equations when solving stoichiometric problems because each kind of atom has to be the same on both sides of the equation. The chemical reactions that take place are molar ratios.
What are some tips for easily balancing chemical equations?
To easily balance chemical equations, follow these tips: Start by balancing atoms that appear only once on each side of the equation. Balance polyatomic ions as single units. Use coefficients to balance the number of atoms on each side. Check your work to ensure the equation is balanced.
What quantity can always be used in the same way as moles when interpreting balanced chemical equations?
The number of molecules
