Why chemical equations used then writing chemical reactions sentences?
It is more simple and practical.
How are coefficients used to balance chemical equations?
In a chemical equation, the coefficients tell you how much you need of each molecule or atom, to balance the equation.
Does a chemical formula describes a chemical reaction?
Yes, chemical equations describe chemical reactions. A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
What information about a chemical reaction is derived from the coefficients in a balanced equation?
Coefficients are used to represent multiple molecules of formula units.
What are codes used in chemical equations telling what atoms are part of the equations?
formulas
Why are coefficients used in chemical equations?
to determine the mole of the atom
What in chemical equations provide mole ratios that can be used as conversion factors?
Coefficients
What is used to balance chemicals equations?
coefficients
Why chemical equations used then writing chemical reactions sentences?

Chemists keep track of which substances are used and created in a chemical reaction by writing what?
chemical equations
Why are coefficient used to balance equations?
Coefficients are used to balance equations because if you change the subscript, than you would change the substance.
What a short easy way to show a chemical reaction using symbols?
Writing a chemical reaction with symbols: Ex.: NaCl + AgNO3 = AgCl (s) + NaNO3 A mathematical (digital) system for the writing of chemical equations exist but it is rarely used.

Are used to denote the of atoms of each in the molecule?
Chemical symbols and coefficients are used.
What information about a chemical reaction is derived from the coefficients in a balanced equation?
Coefficients are used to represent multiple molecules of formula units.
How can balenced equations be used to calculate the volume of gases formed in chemical reactions?
The coefficients in a balanced chemical equation shows how many moles of each reactant is needed in order for a reaction to take place. After determining how many moles of each reactant is required, you would convert it to grams to calculate how much of each reactant is needed to form a given amount of product in a chemical reaction.
