Can a chemical formula be changed during the balancing of the equation?

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.

When we balance a chemical equation we can change the types of reactants or products?

Answer: we can not change the formula of any of the species taking part in the reaction while balancing its chemical equation. Explanation: by changing the formula of any of the reactant or product the whole reaction will be changed.

How do you balance chemical reactants and products?

3 Steps for Balancing Chemical Equations

1. 1) Write the unbalanced equation.
2. 2) Balance the equation.
3. 3) Indicate the states of matter of the reactants and products.
4. 1) Write the unbalanced equation.
5. 2) Balance the equation.
6. 3) Indicate the physical states of the reactants and products.

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.

Why can you not change chemical formulas to balance an equation?

Balancing a Chemical Equation. Because the identities of the reactants and products are fixed, the equation cannot be balanced by changing the subscripts of the reactants or the products.

What Cannot be changed 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!

Why should you not change the subscripts in chemical formulas when balancing chemical equations?

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.

Why must a chemical equation be balanced?

Answer: Chemical reaction is just a rearrangement of atoms. Chemical equations must be balanced to satisfy the law of conservation of matter, that states that matter cannot be produced or destroyed in a closed system. The law of conservation of mass governs the balancing of a chemical equation.

How do you balance a chemical equation?

Balance charge. Add e- (electrons) to one side of each half-reaction to balance charge. You may need to multiply the electrons by the two half-reactions to get the charge to balance out. It’s fine to change coefficients as long as you change them on both sides of the equation.

Which of the following Cannot be changed while balancing a chemical equation?

Why is it incorrect to balance a chemical equation by changing the subscripts?
