We can describe a chemical reaction as a word equation. Read below to find out about word equations and their application in chemistry.
Cookbooks with a bunch of delicious recipes are super useful to whip up a dish that is equally delicious each time it is made. The same idea can be applied to chemical reactions! How can we note down chemical reactions so that you can go through them later?
Read on to find out everything about word equations in chemistry.
You might not notice, but chemical equations are happening all around you.
A chemist can't remember every equation and every reaction occurring accurately. This is why they keep track of equations by noting them down. In every chemical reaction, one or more substances termed reactants are converted to one or more new substances termed as products. The general equation for this would be
Reactants → Products
You must not use an equal sign while representing a chemical reaction.
The words ‘and’ or ‘plus’ mean one chemical and another are both reactants or products.
The phrase ‘is reacted with,’ states that those chemicals are reactants.
Using the words ‘forms’, ‘yields,’ ‘makes’ means the chemicals are products.
Reactants would always be mentioned on the left side while the products are on the right side.
Let us take the chemical reaction
2H2(g) + O2(g) → 2H20(g)
This, in word equation, would be expressed as
Hydrogen gas + Oxygen gas → Steam
Copper + Oxygen → Copper (II) oxide
Another one would be
2Cu + O2→ 2CuO
Here, the chemical equation is completely different, and copper (I) has been used.
1. What are the three common components of a word equation?
The three common components of a word equation are reactants, products, and the direction of the reaction.
2. What does a chemical equation show that a word equation does not?
The chemical equations showcase the chemical formulas that word equations do not.
