What is a good practice to use when balancing equations?
A good practice when balancing equations is to start by balancing the most complex or uncommon elements first, such as those in polyatomic ions or compounds. Then, balance simpler elements like single atoms last. Remember to adjust coefficients, not subscripts, to balance the equation.
When balancing an equation you can only change the which tells you the number of particles that participate in the reaction and comes before the symbol?
You can only change the coefficients when balancing an equation. The coefficients are the whole numbers that come before the chemical symbols of the reactants and products, indicating the ratio of moles of each substance in the reaction.
Why do we use moles to balance equations?
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.
How does a subscript in a chemical formula affect balancing chemical equation?
When balancing a chemical equation, you multiply the subscripts in a chemical formula times the coefficient in front of the formula to get the total number of atoms of each element.

What law is Balancing Chemical equations is a result of?
Balancing chemical equations is a result of the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing the number of atoms on both sides of the equation ensures that the total mass is conserved before and after the reaction.
What should asthma people do before participating in excerise?
it depends on how bad your asthma is. most people with bad asthma use their inhaler before and after exercise if needed
What is the system of equations?
A system of equations is a set of equations with more than one variable dealing with the same material. If there are 2 variables, then the system must have 2 equations before it can be solved. 3 variables need 3 equations, etc.
When balancing an equation you can only change the which tells you the number of particles that participate in the reaction and comes before the symbol?
You can only change the coefficients when balancing an equation. The coefficients are the whole numbers that come before the chemical symbols of the reactants and products, indicating the ratio of moles of each substance in the 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
Why do we use moles to balance equations?

Balancing equations with moles helps predict yields and understand reaction stoichiometry.
What is the law of conservation mass and how is it connected to balancing chemical equations?
The law of conservation of matter/mass states that in a closed system matter is neither created nor destroyed. This means that the same number and kind of atoms in the reactants are also present in the products, which is why a chemical equation must be balanced.
Is the number that appears before a formula in a chemical equations?
The number that appears before a formula in a chemical equation represents the coefficient, which indicates the ratio of moles of each substance involved in the reaction. It is used to balance the equation so that the same number of each type of atom is present on both sides of the reaction.
Who found about linear equations?
Linear equations, maybe not in a form you would recognize, have been around since the ancient Greeks, and maybe before them in China. Diophantus around 250AD wrote about equations. But there was work in that area before him. So there is no single 'who' but like many other things it is a building of knowledge over a long period of time that has evolved into what we now call linear equations.
In order to solve the following system of equations by addition could you do before adding the equations so that one variable will be eliminated when you add them?
Yes, you can manipulate the equations before adding them to eliminate one variable. This can be done by multiplying one or both equations by a suitable coefficient so that the coefficients of one variable become opposites. Once the coefficients are aligned, you can add the equations together, resulting in the elimination of that variable, making it easier to solve for the remaining variable.
