colour, clarity, solid formation, gas formation, release of energy
These are the chemical reactions; chemical reactions contain chemical formulae and are representative for a chemical change.
colour and time liimmite
Positive, negative and neutral.
Well chemical equations can help us understand how a certain substance is made and what combines with what to make it using symbol and word equations .It makes more understanding of the concepts through symbols.
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.
1. The representation of chemicals in chemical equations is made by formulas.2. The word code has another sense in chemistry; as an example, the digital code of the American Chemical Society - Chemical Abstract Service (CAS No).
They are usually much easier to write, and they show what happens to the atoms. Also, it looks more official and scientific. (-:
It is a chemical reaction. Hint: if it has the word "reaction" it. it's probably a chemical process.
* word equations: describe the substances that react in a chemical reaction (termed reactants ), and the products that are formed, along with their states * formula equations are a shorthand method used to describe the same reactions.
its easier
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.
The chemical symbol of calcium is Ca.

chemical change
A chemical change is the same as a chemical reaction.
what is a chemical reaction of a rock
potassium + oxygen --> potassium oxide
Well chemical equations can help us understand how a certain substance is made and what combines with what to make it using symbol and word equations but if you dont know your elements it can be a problem
