Why To balance a chemical equation can we change the formulae of either reactants or products?
if it is a redox reaction sometimes you can add water to help balance the equation
What is the balance of chemical equation involve in evaporation?
Evaporation is not a chemical change and so there is no chemical equation.
What are two things you cannot do to a subscript in a chemical equation?
1. You cannot change the subscript just to help you balance the equation. You can only balance an equation by using whole-number coefficients written at the beginning of a substance. 2. If no subscript is present, you can't just add one to help you balance the equation for same reason listed above.
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 is water change to hydrogen peroxide a chemical change?
Water - H2O; Hydrogen peroxide - H2O2. It is a change of chemical formula , it is another type of molecule.
What are you allowed to do when you balance an equation?
Change superscripts
What is the relationship between coefficient and balance chemical equation?
balance chemical equation, change only the coefficients of the formulas.
What would you change to balance a chemical equation?
you would change the coefficients

When balancing chemical equations why is it permitted to change the numbers in front of the chemical formulas but not the number within the chemical formula?
The chemical formula of a molecule shows how many atoms are in the molecule so you cannot change it since that would mean it is a different molecule then.To balance the equations you have to have the same amount of atoms in the left and right hand side. So you try to balance the numbers of each molecule on each side so that there are for example 3 hydrogen atoms overall on each side.Example:H2 + O2 ---> H2OThis equation is not balanced since there are two H and two O on left side but only one O and two H on the right side. To balance you cannot change the formula from H2O (water) to H2O2 (hydrogen peroxide) because this is a different compound. But you can balance it like this:2H2 + O2 ---> 2H2ONotice that now there are 4H on left hand side (2*2) and 2O, which is the same like the right hand side where you have 4H(2*2) and 2O (2*1 because there is no number after O so there is only 1 atom of it in the molecule)
Can a decimal be a coefficient in a chemical equation?
No! You can change coefficients as needed to balance an equation but you cannot just change a substance's subscripts.
Is this true or false Subscripts can be changed in order to balance a chemical equation?
False. Subscript cannot be change to balance chemical equations. Only coefficients can be added to balance chemical equation.
What is the balance of chemical equation involve in evaporation?
Evaporation is not a chemical change and so there is no chemical equation.
Why is it important never to change a subscription in a chemical formula when balancing a chemical equation?
It is important never to change a subscript {note correct spelling} in a chemical formula when balancing a chemical equation, because changing a subscript produces a formula that specifies a chemical substance different from the one in the original equation.
How can you balance a chemical equation by changing the subscripts?
Balancing only allows you to change the coefficients, NOT the subscripts.
