Can a chemical formula be changed during the balancing of the equation?
1: Balancing Equations. You cannot change subscripts in a chemical formula to balance a chemical equation; you can change only the coefficients. Changing subscripts changes the ratios of atoms in the molecule and the resulting chemical properties.
Why can you not change the subscripts on the chemical formulas in order to balance a chemical reaction?
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.
What must never be changed in order to balance an equation?
The number of atoms of each element on both sides of the equation must be equal because matter cannot be created or destroyed. When balancing equations, the only numbers that can be changed are coefficients. Subscripts in a chemical formula cannot be changed to balance an equation.
What part of the chemical equation needs to be changed to balance an equation?
coefficients
In order to balance the equation, we must change the amounts of the reactants and products, as necessary, by adding coefficients in front of the appropriate formula(s). If you compare the unbalanced equation to the balanced equation, you will see that the chemical formulas of each reactant and product were not changed.
What rules are used to balance a chemical equation?
Use coefficients of products and reactants to balance the number of atoms of an element on both sides of a chemical equation. When an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced.
When balancing a chemical reaction you will need to check and possibly change the?
Remember, to balance an equation, you change the coefficients, not the subscripts in the formulas. Once you have balanced one element, do the same thing with another element.
Is reducing subscripts necessary?
Transpose only the number of the positive charge to become the subscript of the anion and the number only of the negative charge to become the subscript of the cation. 3. Reduce to the lowest ratio. This step is not necessary.
Can a chemical equation be balanced and incorrect?
Presenting it as being balanced would be wrong. In the example equation, there are two atoms of hydrogen on each side, BUT there are two atoms of oxygen on the left side and only one on the right side. Remember this: A balanced equation MUST have EQUAL numbers of EACH type of atom on BOTH sides of the arrow.
Which of the following Cannot be changed while 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!
Why we should balance the chemical equation?
A chemical equation should always be balanced because the law of conservation of mass states that matter can neither be created nor destroyed so in a chemical equation the total mass of reactants must be equal to the mass of products formed i.e. the total number of atoms of each element should be equal on both the …
