If your goal is to balance the equation, then yes, you have to chose the coefficients.
Tsubscripts of the reactants equal the subscripts of the products.
The chemical equation is:SF4 + 2 H2O = SO2 + 4 HF
Stoichiometric coefficients.
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.
1,1,2
1,1,1
If your goal is to balance the equation, then yes, you have to chose the coefficients.
That's not an equation
The balance equation would be 4Fe + 3O2 ==> 2Fe2O3, so the coefficients are 4, 3, 2.
balance chemical equation, change only the coefficients of the formulas.
I think moles
you would change the coefficients
Tsubscripts of the reactants equal the subscripts of the products.
There are 2 oxygen on the left and one on the right. To balance the oxygen the blank will be 2. To balance out the lithium there are 4 on the right and there needs to be 4 on the right. So yes the sum of the coefficients is 7.
False. Subscript cannot be change to balance chemical equations. Only coefficients can be added to balance chemical equation.
Balancing only allows you to change the coefficients, NOT the subscripts.
