What else can I help you with?
What number is never written in the formulas for chemical compounds?
The number ONE is never written in the formula for a chemical coumpound because it will be assumed. ONE is the number!
What must be known before a chemical equation can be written?
We need to know the reactants and products with their chemical formulas.
What are two advantages that chemical equations written with symbols and formulas have over word equations?
Chemical equations written with symbols and formulas provide precision and clarity in representing the reactants and products involved in a reaction. They also allow for easy stoichiometric calculations and a more concise way of expressing chemical reactions.
H2O CO2 and C12H22O11 are all examples of chemical .?

What are Chemical formulas for ethanol?
The molecular formula of ethanol is written as either CH3CH2OH or C2H5OH, and its empirical formula is C2H6O. It is often written as EtOH.
What are all chemical formulas called?
All chemical formulas are called chemical notations. They represent the elements and the number of atoms of each element present in a compound.
What are some metals that do not have chemical formulas?
The metals by themselves do not have chemical formulas, they have chemical symbols which are shown on the periodic table of the elements. They only have chemical formulas if they are chemically bonded to another element, usually a nonmetal.
What is an expression representing a chemical reaction the formulas of the reactants are connected by an arrow with the formulas for the products called?
Chemical equation
What is written in front of the formula used to balance chemical equations?
The reactants are written on the left side of the equation, while the products are written on the right side. The equation is balanced by adjusting the coefficients in front of the chemical formulas so that the number of atoms for each element is the same on both sides.
Why are the numbers all so small and written lower than normal in chemical formulas?
The subscript Number of atoms of that element in the molecule.
H2o co2 and c12h22O11 are examples of chemical?
Chemical Formulas
What is a method to indicate reactants and products of a chemical reaction using chemical formulas?
In a correctly written chemical equation, reactants are the substances to the left of the arrow, and products are the substances to the right of the arrow. The reactants are what you have before the reaction starts, and the products are what you have when the reaction is over.
