As a chemical engineer, or as a former teacher, I have always been curious about these little, yet frequently overlooked, rules of writing chemistry formulas.

Well, it’s true that you can write a chemical formula without using parentheses. But here’s the thing: writing a formula without parentheses is a mistake. It’s just like writing a chemical equation without parentheses. A formula without parentheses doesn’t have any meaning because it’s no longer a simple algebraic expression. It’s just a bunch of letters. It’s not that surprising because I’ve seen people write chemical formulas with no parentheses before.

So, without parentheses, you make a chemical formula that has no meaning. If you want to know what a chemical formula looks like, check out this picture.

I was recently reminded of this when I read about the death of British chemist William Bragg. He was the inventor of the Bragg-Ullman reaction, a technique for making water by reacting it with nitrous acid. He died of cancer in 1938.

The chemical formula is the key to understanding the nature and properties of any chemical. The number of letters in the formula is the number of atoms in the molecule. An atom is a single atom in a chemical formula. With a single letter you have no atoms.

A chemical formula is a mathematical formula. The number of letters in a chemical formula is the number of atoms in the formula. For example, the number of carbon atoms in a molecule is the number of carbon atoms in the molecule. For example, a molecule of helium has a number of carbon atoms, one atom, two carbon atoms, and one carbon atom. The number of carbon atoms in a molecule is the number of carbon atoms in the molecule.

The number of atoms in a chemical formula is a number that is expressed in terms of integer numbers. To give a simple example, the number of atoms in a molecule like carbon dioxide is a number that is expressed in terms of 10. To give a more complex example, the number of carbon atoms in a molecule like carbon dioxide is a number that is expressed in terms of 10.000.000.000.000.000.000.000.000.000.000.000.000.

The first time I read this sentence, I thought I was in the middle of a science class. I was thinking about the fact that the number of atoms in a molecule is a number that is expressed in terms of integer numbers. In reality, the number of carbon atoms in a molecule like carbon dioxide is a number that is expressed in terms of 10. In reality, the number of carbon atoms in a molecule like carbon dioxide is a number that is expressed in terms of 10.000.000.

It’s a common pitfall to write a formula the way you’d write one of your own equations. Since the same symbols are used in a formula and in an equation, the formula has to be rewritten, and the equation re-written again. If this is all you are doing, you can do it yourself, but I would argue that it’s always better to use parentheses to express your formulas. And that’s true regardless of the number of atoms in a molecule.
