What are the advantages of chemical equations?
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.
What are word equations in chemistry?
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.
Chemical are codes used in chemical equations?
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).
Why do scientists like to use chemical equations instead of word equations?
They are usually much easier to write, and they show what happens to the atoms. Also, it looks more official and scientific. (-:
Is Oxygen and hydrogen combining to form water a physical or chemical change?
It is a chemical reaction. Hint: if it has the word "reaction" it. it's probably a chemical process.
What is the difference between a formula equation and a word equation?
* 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.
Why do scientists use chemical equations instead of word equations?
its easier
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.
Word equations for calcium?

Is the word tarnishing a physical change or a chemical change?
chemical change
What is the word for a chemical change in a substance?
A chemical change is the same as a chemical reaction.
What word equations show chemical changes in rock?
what is a chemical reaction of a rock
What are the chemical and word equations for the reaction that causes potassium to tarnish?
potassium + oxygen --> potassium oxide
What are the advantages and disadvantages of equations?
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
