How would changing a coefficient differ from changing the subscript?
The subscript tells you what the substance it. It tells you the the amount of each element there are in the molecule. Changing it would change the substance itself. Whereas simply changing the coefficient means you’re changing the amount of molecules.
What can you never change when balancing a chemical equation?
When you balance an equation you can only change the coefficients (the numbers in front of molecules or atoms). Coefficients are the numbers in front of the molecule. Subscripts are the smaller numbers found after atoms. These cannot be changed when balancing chemical equations!
Whats the difference between a coefficient and subscript?
Subscripts – Part of the chemical formulas of the reactants and products that indicate the number of atoms of the preceding element. Coefficient – A small whole number that appears in front of a formula in a balanced chemical equation.
What is the importance of the coefficients in a balanced chemical reaction?
Stoichiometric coefficients are the coefficients required to balance a chemical equation. These are important because they relate the amounts of reactants used and products formed. The coefficients relate to the equilibrium constants because they are used to calculate them.
Why can you only change the coefficients but not subscripts?
When you change the coefficients, you’re only changing the number of molecules of that particular substance. However, when you change the subscripts, you are changing the substance itself, which will make your chemical equation wrong.
When coefficients are added the type of compounds is changed in the chemical reaction?
-When coefficients are added the type of compounds is changed in the chemical reaction. -Coefficients are added to compounds to ensure both sides of the reaction have equal numbers of each atom. -Subscripts are multiplied by the coefficients to determine the number of atoms in a compound.
What number do you never write as a coefficient?
When no coefficient is written in front of a formula it is assumed to be 1. 4. Numbers appearing in the formulas are known as subscripts. These can never be changed when balancing the equation or you will change the identity of the substance.
Why are coefficients used in mole ratios instead of subscripts?
Coefficients indicate how many of each compound is involved in a reaction (i.e. the number of moles of each compound).
