What is the difference between substances co and co

Excess carbon dioxide uses up space in the air instead of oxygen , creating an environment for asphyxiation. Symptoms of mild carbon dioxide poisoning include headaches and dizziness at concentrations less than 30, ppm. At 80, ppm, CO2 can be life-threatening. Carbon monoxide is a far more dangerous gas. The exposure level considered immediately dangerous to life and health IDLH is ppm.

When it comes to choosing an industrial gas detector for the workplace, a single-gas carbon monoxide detector will not measure carbon dioxide levels, nor does it work the other way around. The sensors are specific for each gas. Carbon Monoxide Vs. Where does carbon dioxide come from? See the technology that makes gas detection easy.

For example, CO means a molecule of carbon monoxide but Co is the symbol for cobalt an element. The word 'formulae' is the plural of 'formula'. If we have more than one formula, we don't say formulas, we say formulae. We use numbers to show when a molecule contains more than one atom of an element. The numbers are written below the element symbol. For example, CO 2 is the formula for carbon dioxide. It tells you that each molecule has one carbon atom and two oxygen atoms.

Take care when writing these formulae. The small numbers go at the bottom.
