What else can I help you with?
Is this true or false Subscripts can be changed in order to balance a chemical 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.
What is a number added to an atom or molecule to help balance a chemical equation?
A coefficient.
What is the term for the numbers added in front of some compoundes to balance a chemical equation?
I think moles
What can be added to a chemical equation to make it balanced?
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.
What is nthe term for the number added in front of some compounds to balance a chemical equation?
They are coefficients, and in most cases, they are whole numbers.
What is the name of the large whole number added to the front of a compound to balance equation?
To balance a equation, the whole number added or used in front of a compound is known as Coefficient.
Why are reactants important in a chemical reaction?
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.
Can the subscripts be changed in order to balance a chemical epuation?
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).
What is the balance chemical equation for the first law of thermodynamics?
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
What is the chemical equation for the reactions when copper is added to aluminum sulfate?
The chemical equation for the reaction when copper is added to aluminum sulfate is: 3Cu + 2Al2(SO4)3 -> 3CuSO4 + 2Al
What needs to be added to balance the equation for the decomposition of mercury oxide?
its already balanced
What is the Chemical equation for iron added to hydrochloric acid?
FeCl+H2(g)
