a balanced equation has equal numbers of each type of atom on each side of the equation.
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.
A coefficient.
I think moles
Coefficients can be added in front of the chemical formulas to balance a chemical equation. These coefficients represent the number of molecules or atoms of each substance participating in the reaction. Balancing ensures that the same number of each type of atom is present on both sides of the equation.
They are coefficients, and in most cases, they are whole numbers.
To balance a equation, the whole number added or used in front of a compound is known as Coefficient.
Reactants are added into the equation to form the chemical reaction. Reactants are substances that are changed into products. Without these reactants, there would be no formula, resulting in no product.
No, or you'd change the chemicals being reacted. Added: There is always ONE and ONLY ONE way in which you can put the right COEFFICIENTS of each reacting compound in a balanced equation, by only changing the values of those coefficients. (That are the figures in FRONT of the chemical formula's).
dU=q-w where dU is the differential change in internal energy q is the differential quantity of heat added to a system w is the differential quantity of work done by a system on its surroundings
The chemical equation for the reaction when copper is added to aluminum sulfate is: 3Cu + 2Al2(SO4)3 -> 3CuSO4 + 2Al
its already balanced
