You need to have it stochiometrically balanced so that in the area of organic chemistry for instance, you can directly associate how many moles of a product should form (percentage yield). Equally in analytical chemistry, for acid/base titrations for instance, you need to know the stochiometric amount of reactants to calculate how much of an unknown there is. For example, if you have NaOH
reacting with an acid, if you said there was a 1:1 equivalence between base and acid and your acid was sulphuric acid (1:2 equivalence), you would calculate that there was half of the amount of sulphuric acid in sample as there actually was.

Is it true that subscripts can be changed in order to balance a chemical equation?
No, subscripts cannot be changed in a chemical formula to balance a chemical equation. Balancing a chemical equation involves adjusting the coefficients in front of the chemical formulas to ensure that the number of each type of atom is the same on both sides of the equation. Changing subscripts would alter the chemical identities of the substances involved.

false
What may be changed in order to balance a chemical equation?
Coefficients can be adjusted to balance a chemical equation. Coefficients are placed in front of chemical formulas to ensure that there is the same number of each type of atom on both sides of the equation. The goal is to have an equal number of atoms of each element on the reactant and product sides.
Is this true or false Subscripts can be changed in order to balance a chemical equation?
True. Subscripts represent the number of atoms of each element in a compound and changing them would change the chemical formula, possibly making it unbalanced in the equation. By adjusting the coefficients of the compounds involved in the reaction, the equation can be balanced without modifying the subscripts.
Can you change the number of atoms in each molecule or formula in order to balance an equation?
Yes, you can change the coefficients in front of the molecules or formulas in a chemical equation to balance it. Balancing the equation ensures that the same number of each type of atom is present on both sides of the equation.
What is the coefficent that shows in a chemical equation?
Equations for chemical reactions may require one or more whole-number coefficients in order for the equation to balance. Balancing a chemical equation upholds the law of conservation of mass, which states that matter cannot be created or destroyed. The coefficients represent molar ratios of reactants and products. Performing stoichiometric calculations is largely dependent upon these correct molar proportions.
The numbers which are placed in front of each reactant and product in order to balance the equation are called?
The numbers placed in front of each reactant and product to balance the equation are called coefficients. These coefficients help ensure that the number of atoms for each element is the same on both sides of the chemical equation.
A chemical reaction is balanced by changing?
To balance a chemical equation, you can change the coefficients (number of molecules). Remember: You cannot change the subscripts.When we balance an equation we change the number of atoms on one or both sides of the equation by means of simple mathematical calculation. That is, we change the number of molecules of one or more reactants or products. When the number of atoms of each element is equal on both sides of the equation, and cannot be reduced equally, the balancing process is complete.
What are some tips for balancing easy chemical equations effectively?
To balance chemical equations effectively, follow these tips: Start by balancing atoms that appear only once on each side of the equation. Use coefficients to balance the number of atoms on both sides. Balance the elements in the order of least complex to most complex. Check your work by counting the number of atoms on each side of the equation.
What particles must have an equal number on both sides of a chemical equation?
Due to the law of conservation of mass and matter, all particles must have an equal number on both sides of a chemical equation. An equal number of atoms of each element involved must be on each side of the equation.
What is the role of coefficients in chemical equations?
An unbalanced equation has more reactants than products, or vice versa. Stoichiometry, the science of balancing equations, uses coefficients to balance both sides of the reaction to follow the Conservation of Mass. Ex: Ca + H2O --> H2 + Ca2O3 This is unbalanced because there is one more calcium atom and two more oxygen atoms produced than there were put in. 2Ca + 3H2O --> 3H2 + Ca2O3 Now the equation is balanced, with the products equivalent to the reactants.
How can you balance a chemical equation using coefficients?
Co-efficients are written in a chemical equation to balance the equation. this is due to the conservation of mass seeing how we can't make substances out of nothing. For Example. NaOH + H2SO4 --> Na2SO4 + H2O As you can see on the left side, there is only one Na (sodium) atom, but on the right hand side we have 2. meaning that an extra sodium atom appeared from no where and this VIOLATES the conservation of mass. so we must balance is 2NaOH+H2SO4 --> Na2SO4 + 2H2O There are 2 Na on both sides There is 1 sulfur (s) on both sides there is 4 H on both sides and 6 oxygen on both sides. Hope this helps :D
