How are coefficients used in writing chemical equations?
They indicate the number of molecules in a substance.
What does conservation mean when relating to chemical reactions?
"Conservation" in chemical reactions referrs to something that is the same before and after the reaction. When writing a chemical equation, balancing the equation represents the 'conservation of atoms' and the 'conservation of mass'. Add all the atoms of each individual type on the reactant side of the arrow and, individually, the number of atoms on the product side for each type of atom will be the same. Atoms cannot be created or destroyed by a chemical reaction.
Why do scientists use word and symbol equations to represent chemical reactions?
Because writing: HCl(aq) + NaOH (aq) -> H2O (l) + NaCl (aq) takes a lot less time than writing: Hydrochloric acid and Sodium Hydroxide react in solution to produce water and aqueous Sodium Chloride.
How can chemical equations be used to describe what happens in chemical reactions?
A chemical formula or molecular formula is a way of expressing information about the atoms that constitute a particular chemical compound.The chemical formula identifies each constituent element by its chemical symbol and indicates the number of atoms of each element found in each discrete molecule of that compound. If a molecule contains more than one atom of a particular element, this quantity is indicated using a subscript after the chemical symbol (although 18th-century books often used superscripts) and also can be combined by more chemical elements. For example, methane, a small molecule consisting of one carbon atom and four hydrogen atoms, has the chemical formula CH4. The sugar molecule glucose has six carbon atoms, twelve hydrogen atoms and six oxygen atoms, so its chemical formula is C6H12O6.Chemical formulas may be used in chemical equations to describe chemical reactions. For ionic compounds and other non-molecular substances an empirical formula may be used, in which the subscripts indicate the ratio of the elements.The 19th-century Swedish chemist Jöns Jacob Berzelius worked out this system for writing chemical formulas.
Why does his teacher ask him to balance the equation by including the correct coefficients?
It is important to balance the equation, so that you know the exact ratio of reactants required and products formed. If you don't consult a balanced equation, some of your reactant may not completely consume in reaction or sufficient product is not formed during experiments.
How do you show chemical reactions in writing?
chemical equations
Chemists keep track of which substances are used and created in a chemical reaction by writing what?
chemical equations
How can you show a chemical reactions in writing?
well to be honest i don't no
How are coefficients used in writing chemical equations?

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.
What is chemical bookkeeping?
Symbols are used for elements, when writing chemical compounds. These clearly show reactions between molecules. This is chemical bookkeeping.
How are abbreviations and symbols alike?
Abreviations and symbols in science are both used as a shorthand system for frequently referenced concepts in writing. Symbols are used in mathematical equations to stand for constants or variables. As examples:In Chemical reactions: NaCl is table saltIn Chemical equations: 2H2 +O2 -> 2 H2OIn mathematical equations: E=MC^2In science literature: LSD is used in place of lysergic acid diethyl amideAs constants in physics equations: density is replaced by ρ (the lower case Greek letter rho)
When to use punctuation?
When writing. At the end of sentences, in sentences. Basically anywhere in your writing piece.
What is the purpose of writing a word equation in chemistry?
It is one way of representing a chemical reaction: it tells you what reacts and what is produced. Word equations are an efficient way to describe chemical changes, to help chemists recognize patterns, and to predict the products of a chemical reaction.
