How to solve chemical equations?
:A balanced equation MUST have EQUAL numbers of EACH type of atom on BOTH sides of the arrow.An equation is balanced by changing coefficients in a somewhat trial-and-error fashion. It is important to note that only the coefficients can be changed, NEVER a subscript.
Can the subscripts be changed in order to balance a chemical epuation?
No, or you'd change the chemicals being reacted. Added: There is always ONE and ONLY ONE way in which you can put the right COEFFICIENTS of each reacting compound in a balanced equation, by only changing the values of those coefficients. (That are the figures in FRONT of the chemical formula's).
Why can't a subscript in a formula of a chemical compound change when balancing an equation?
Answer 1To balance an equation means that there are the same number of each element on each side. The reason a subscript cannot change is that it represents the amount of an element within a certain compound in relation to any other elements. If that ratio changes, it is no longer the same compound. Changing a subscript changes a formula so that it no longer stands for the correct substance.Answer 2The point of balancing an equation is to find the ratios in which chemicals will react or be produced. By changing the equation, you change the reaction. Therefore you are not trying to balance the same reaction.Answer 3A balanced chemical equation is the standard way of writing equations for chemical reactants because it follows the LAW OF CONSERVATION OF MASS.Because there is a total of four atoms in the reactants, a total of four atoms must be in the products.Answer 4Changing the subscripts changes the compounds in the reaction. A subscript in the formula can not be changed when balancing an equation because changing a subscript would make the formula describe a different compound, or rather more likely a non-existent compound.Answer 5If the subscript of the element while balancing is changed, then the entire molecule gets changed !For eg: Fe2O3 and Fe3O4 are entirely different compounds with diff. properties, colour , magnetic behaviour etc. This would basically be changing the element altogether. Think about the difference between O2 and O3. O2 is regular oxygen-the air we breathe. O3, on the other hand, is what makes up the ozone. so, instead of changing O2 to O6, you put 3O2 to say that you have three O2 atoms, not an O6 atom. I hope I was able to clarify that.Answer 6The subscripts represent the number of atoms of each element in each chemical formula-if you change the subscripts, you change the compounds the formulas are describing.
What is the first step in balancing a chemical reaction?
Rules of balancing chemical equations:1. write the unbalanced equation2. count the number of atoms of the same element on reactant and product side of equation3. make the number of atoms the same by changing the coefficients, not subscripts4. balance hydrogen and oxygen last5. reduce coefficients if possibleThe first step in balancing a chemical equation is identifying all elements.For example:H2OSo the elements you would identify are H (hydrogen) and O (oxygen).--------------------------------------------------------------------------------------------------------b. identify the reactants and products. - (e2020)
Why can you add coefficients to an equation but not change subscripts of a formula?
In a chemical formula, changing the coefficient only changes the amount of the substance present. Changing a subscript changes the number of atoms in the compound, thus changing the chemical properties of the compound.
Are chemical equations balanced by changing the subscripts of the molecules?
No - they are usually balanced by changing the numbers before the molecules.
Are Chemical equations are balanced by changing the subscripts of the molecules?
ABSOLUTELY NOT Change the coefficients on reactant or productt units.
How can you balance a chemical equation by changing the subscripts?
Balancing only allows you to change the coefficients, NOT the subscripts.
Equations show each side is equal as far as the number of atoms and molecules?
this is called having a balanced equation .....if both sides are not balanced u must correct it by changing the number of moles
Changing subscripts is one of the steps of balancing a chemical equation.?
f fales
Changing subscripts on the product side but not on the reactant side is a good way to balance a chemical equation.?

Why can't you balance an equation by changing the subscripts of the reactants or the products?
You can't change the subscript. The subscripts show how the elements/molecules are bonded.--------------------------------------------------------------------------------------------------------The subscripts represent the number of atoms of each element in each chemical formula-if you change the subscripts, you change the compounds the formulas are describing.Source: (e2020)

Why cant you change the charge of an ion to make formulas?
You can't change the charge because that is changing the very chemical nature of the ion/atom. To make formulas with ions, you use subscripts to change the NUMBER of ions in the formula without changing the CHARGE.

Is a chemical equation balanced by changing or adding?
The subscripts determine what the chemicals are, you have to change the amount of the reactants/products rather than change what the reactants/products actually are eg O2 is oxygen gas, if you wanted 4 of them to balance it it would have to be 2 O2 otherwise it wouldn't be oxygen gas any more.
