If you were to describe a chemical reaction in a sentence, it would be quite long. To express it in a shorter form, we can write it as a word-equation. For example, the reaction between magnesium and oxygen to give magnesium oxide can be represented as follows – Magnesium + Oxygen →...
If possible, make the equation more informative by indicating the physical states of the reactants and products, the heat changes that occur in the reaction, and the conditions under which the reaction occurs. This step may be skipped if you do not have enough information about the physical s...
For example, the reaction of ethane (C2H6) with oxygen yields water and carbon dioxide, which can be represented by the following unbalanced equation: The unbalanced equation contains: AtomsReactantProductBalanced? C21No H62No O23No To balance the number of carbon atoms and hydrogen atoms, multip...
Every time you strike a match, burn a candle, build a fire, or light a grill, you see the combustion reaction.Combustioncombines energetic molecules with oxygen to produce carbon dioxide and water. For example, the equation forthe combustion reactionof propane, found in gas grills and some fi...
This lesson will cover what happens when a chemical reaction occurs, the types of chemical reactions, and how to know if a chemical reaction occurs.

A balanced equation contains the same number of each type of atoms on both the left and right sides of the reaction arrow. To write a balanced equation, the reactants go on the left side of the arrow, while the products go on the right side of the arrow. ...
A chemical equationcan be used to describeaphysicalreaction, which involvesachangeofstates, for example, melting, sublimation, evaporation, etc. 化学方程式被用来描述一个化学反应,其中包含了状态的改变,比如说融化、升华和蒸发等。 ParaCrawl Corpus
where A and B may be either elements or compounds. Here are some examples: Decomposition reaction: In this type of reaction, a single reactant, a compound, breaks into two or more parts. Often these are the most difficult to predict. Here is the general equation: AB→A + B ...
