what is the difference between chemical reactions from chemical equations?

Answer 1

A reaction is a event...a occurrence between atoms


equation is the mathematical part.

Answer 2

Chemical Reaction = The reaction of two or more elements together results in the formation of a chemical bond between atoms and the formation of a chemical compound.

Chemical Equations = symbolic representation of a chemical reaction where the reactant entities are given on the left hand side and the product entities on the right hand side such as CH4 + 2 O2 → CO2 + 2 H2O.

Answer 3

A chemical equation is the "sentence" used to represent the chemical reaction that is taking place. In other words the chemical equation for the formation of salt would be Na+Cl=NaCl whilethe reaction would be just sodium+chloride=salt, salt being the product of the reaction.

Answer 4

Chemical reaction is a process that results in the interconversion of chemical substances. The substance or substances initially involved in a chemical reaction are called reactants. Chemical reactions are characterized by a chemical change, and they yield one or more products which are, in general, different from the reactants. Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformations of elementary particles, as well as nuclear reactions.

A chemical equation is a symbolic representation of all of the substances involved in a chemical reaction. We use the chemical formulas of substance to represent each chemical specie involved in the reaction. We also use the notation (g), (l), (s), or (aq) following the chemical formula to identify the phase of the substances in the equation.

Answer 5

Chemical changes are the changes in the status of a chemical or chemicals. Chemical reactions are the interacting of 2 or more chemicals at once, and it causes 1 or more chemical change(s).

Answer 6

Chemical equation is the short hand way to write how a reaction will happen. It also indicates the ratio that the reactants must be in for the reaction to work.

Example: I work with a tool that has to reduce copper oxide to pure copper. The chemical equation for copper oxide reduction by hydrogen is:

CuO(s) + H2(g) --> Cu(s) + H2O(l)

This indicates that you need 1 molecule of diatomic Hydrogen to reduce 1 molecule of Copper Oxide.

If you had monotomic Hydrogen (something you would probably not have to deal with as monotomic hydrogen is unstable), then you would need 2 molecules of hydrogen (or atoms in the case of monotomic hydrogen) to reduce one molecule of CuO.

Example: CuO(s) + 2H(g) --> Cu(s) + H2O

Chemical equations represent, in writing, the chemical reaction (i.e. the actual physical stuff happening).

I hope this helps.

Answer 7

A reaction is a process. An equatiion is a chemical sentence.

Combustion is a reaction of the combination of a material with oxygen.

CH4 + O2 ---> CO2 +2 H2O equation of the burning of methane

Answer 8

An equation is a representation of what is occurring in a chemical reaction a way to quantify what is happening in the real world

Answer 9

I think that chemical equations are the balanced forms of chemical reactions. Hence the term equation because both sides are equal in a balanced reaction.

So balanced reaction is the equation.

Answer 10

the reaction is the actual change in the chemicals. the equation uses symbols to represent the reaction.

Answer 11

chemical reaction is something that happens b/c you mix two or more diff chemicals together. chemical equations is like a math equation i guess. its just an equation
