Right and down the symbol of a chemical element.
No - they are usually balanced by changing the numbers before the molecules.
ABSOLUTELY NOT Change the coefficients on reactant or productt units.
The term for numbers that appear in the chemical formulas of compounds is "subscripts." Subscripts indicate the number of atoms of each element in a molecule. Coefficients, on the other hand, refer to the numbers placed in front of compounds in a chemical equation to indicate the number of molecules involved.
These subscripts are down the chemical symbol and at right. Example: O2
subscripts
Changing subscripts in a chemical formula changes the actual chemical species present, leading to a different reaction. Subscripts represent the ratio of elements in a compound and should not be changed to balance chemical equations. Balancing equations is done by adjusting coefficients in front of chemical formulas, not by changing subscripts.
No - they are usually balanced by changing the numbers before the molecules.
Changing subscripts in a chemical formula changes the identity of the compound, which is not allowed when balancing chemical equations. Balancing equations involves adjusting the coefficients in front of the chemical formulas to ensure that the same number of each type of atom is present on both sides of the equation.

formulas
Subscripts in a chemical equation indicate the ratio of atoms of each element in a compound. They provide information on the number of atoms present in a molecule and help to balance chemical equations by showing the correct stoichiometry of the reaction.
False. Chemical equations are balanced by changing the coefficients in front of the chemical formulas, not the subscripts within the formulas. The number of atoms of each element must be equal on both sides of the equation to ensure that mass is conserved.
It is important to never change the subscript in a chemical formula when balancing a chemical equation because subscripts represent the number of atoms of each element in the compound. Changing subscripts would alter the chemical formula and consequently change the identity of the compounds involved in the reaction. Balancing equations involves adjusting coefficients, not subscripts.
Coefficients are used to balance chemical equations. These numbers are placed in front of the chemical formulas to ensure that the number of atoms on both sides of the equation are equal.

True. Subscripts represent the number of atoms of each element in a compound and changing them would change the chemical formula, possibly making it unbalanced in the equation. By adjusting the coefficients of the compounds involved in the reaction, the equation can be balanced without modifying the subscripts.
In Microsoft Word, chemical equations can be entered using special character menus. For example, subscripts and superscripts can be used to denote isotopes, and arrows can indicate reactions.
