Most fuels are based on hydrocarbons. When hydrocarbons are burned (oxidized), a significant amount of chemical energy is released in the form of heat.
C11H17N is a chemical formula. Chemical formulas are not based on the quantity of the substance.
The formula is based on the chemical composition of the molecule.
Chemical changes happen everywhere in a cell. Cells are chemical engines, everything they do is based on chemical reactions.
One example of a chemical health hazard is mixing ammonia-based cleaner with a chlorine-based cleaner. Poison gas is produced.

A colorimeter can be used for that purpose.

Using a proper instrument of measure based on the IS. Good luck.
Volume is not a chemical property of matter. It is actually a physical property of matter. Since volume changes based on the amount of matter, it is an extensive physical property.
Chemical Oxygen Demand (COD) is a labortory test to give a measure of the amount of reactive organic materials in a sample of water. Like the five day Biochemical Oxygen Demand (BOD5) it demonstrates the amount of organics present by how much oxygen they consume over a period of carefully controlled conditions (the starting and ending oxidant concentrations are measured and the temperature is controlled)
There is no particular instrument used for measuring tornado intensity. Ratings are based primarily on damage assessment. Occasionally doppler radar has measure wind speeds inside a tornado, but such measurements are rare.
-Due to the principle of constant proportions -It can be accurately measured with a simple chemical analysis
The joule is a measure of energy, and is not a specific currency of a country. Although energy is traded based on the amount of Joules.
chemical based industries is industries that use chemical to production of goods are called chemical based industries
