When balancing a chemical equation is there more than one possible answer?

Technically no, but if you count factorising the number of specific molecules then there is, but it should always be given in the lowest common factor, for example:
6CO2 + 6H2O -> C6H12O6 + 6O2 (photosynthesis)
could also be written as:
12CO2 + 12H2O -> C6H12O6 + 12O2
But you would always use the lowest factors for chemical equations, thus the '12's become '6's as they are common factors.

What does a balanced chemical equation prove?
One or more products containing the same quantity of atoms as the reactants had
What is the difference between a math equation and a chemical equation?
A math equation uses variables and numbers, while a chemical equation uses compounds and mole ratios.
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)
What is the balance chemical equation for the first law of thermodynamics?
dU=q-w where dU is the differential change in internal energy q is the differential quantity of heat added to a system w is the differential quantity of work done by a system on its surroundings
What type of chemical equation is2KNO3s --- 2KNO2s O2g?
That's a decomposition reaction. One reactant, two (or more) simpler products.
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 chemical reaction between two or more substances is described using what equation?
A chemical equation.
What is the need to balance a chemical formula?
When designing a chemical process in a plant, the accountants need what is called a mass balance. This way the product can be costed and a selling price and profit margin derived. For accurate costing, the number of moles must be known and with molecular weight the amount can be derived. This can only be done with a balanced chemical equation.

What is Trial and error method of balancing chemical equations?
it is tedious and takes a long time it is quite difficultto balance a chemical equation
If a chemical equation is not balanced it violates what law?
If a chemical equation is not balanced, it implies that one side of the equation has more mass than the other side. Therefore, it violates the Law of Conservation of Mass.
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 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.
