What represents chemical names of substances in a chemical equation?

∙ 12y ago
In a chemical equation, each element has a symbol (in the Periodic Table in the elements). You use those symbols to create a chemical equation. For example, water is H2O. "H" represents Hydrogen, "O" represents Oxygen and the 2 means that there are two oxygen particles for each oxygen particle. Together, this creates one water molecule.

An unbalanced chemical equation?
An unbalanced equation that uses names of the substances instead of chemical formulas is called a word equation. As a rule, metallic elements are named first and non-metallic next. The suffix of the latter is changed into "ide".
What are the names of the products in photosynthesis chemical equation?
6CO2 + 6H20 ---(sun's energy)--> 1C6H12O6 + 6O2 Carbon Dioxide + Water ---(sun's energy)--> Glucose + Oxygen
How is a chemical equation defined?
When a chemical reaction occurs, it can be described by an equation. This shows the chemicals that react (called the reactants) on the left-hand side, and the chemicals that they produce (called the products) on the right-hand side. The chemicals can be represented by their names or by their chemical symbols. Unlike mathematical equations, the two sides are separated by an arrow, that indicates that the reactants form the products and not the other way round. Any chemical change in substance whether combination, decomposition, displacement or arrangement of the molecules of the substance which involves the transformation of matter into a new substance is termed as chemical equation.
What are the names for a pereodic table?
These names are the names of chemical elements.
The general chemical equation X Y to XY in words?
If you want to react say , hydrochloric acid with zinc, the word equation is : - Hydrochloric Acid and Zinc react to produce Zinc Chloride and Hydrogen . The chemical equation is 2HCl(aq) + Zn(s) = ZnCl2(aq) + H2(g) (aq) means aqueous solution (s) means solid (g) means gas.

In a chemical formula what is used to indicate the number of atoms of each element?
It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
Is there such thing as scientific names of substances?
Yes; today official scientific names of chemical substances are established by IUPAC (International Union of Pure and Applied Chemistry). Each country has a specific adaptation for this terminology. Also, exist numerical codes for chemical substances: CAS registry number (CAS is Chemical Abstract Service).
What is the difference between a word equation a formula equation and a chamical equation?
A chemical formula is the way a particular chemical (element or compound) is represented using the letters given in the Periodic Table. For example, the chemical formula of oxygen is O2 and the chemical formula of caron dioxide is CO2A word equation describes a chemical reactionusing the names of chemicals only. For instance, the word equation for respiration is:glucose + oxygen => carbon dioxide + waterA formula equation also describes a chemical reaction, but uses chemical formulae instead of names and is balanced. An example of this would be methane burning in oxygen:CH4 + 2O2 => CO2 + 2H2O
How is chemistry related to painting?
i know paint pigments are based on chemical compounds, that's why they have names like titanium white or cadmium yellow.
What are the names of the products in photosynthesis chemical equation?
6CO2 + 6H20 ---(sun's energy)--> 1C6H12O6 + 6O2 Carbon Dioxide + Water ---(sun's energy)--> Glucose + Oxygen
What is a word equation and a formula equation?
A word equation is where you describe a reaction using the chemicals by their names Eg. Hydrogen+Oxygen>Water A formula/symbol equation is where you use each chemical's formula (which is a group of the elements it consists of) Eg. H2+O2>H2O (you should use small letters for the numbers after the element)
What is a way to show chemical reactions using symbols instead of words?
a formula equation

Is ch4 4cl2ccl4 4hcl endothermic?
You did not write any of those chemical names correctly (methane is CH4, not ch4) and all you did was list 4 incorrectly written chemicals, you did not give a chemical equation. Only a chemical reaction can be described as endothermic or exothermic; chemicals by themselves do not have those properties.
What is the five basic substance name?
could i have 5 names of mixtures the 5 names of mixtures are variable mixture,constant mixture,homogeneous liquid mixture,homogeneous solid mixture and chemical mixture
