Both, usually. Consider a compost heap in the back garden - this is decomposing plant matter. The decomposition is chemical as compounds break down into smaller, simpler organic molecules and heat is given off (exothermic). Decomposition is also physical as some of the simpler molecules produced by decomposition includes liquids and gases so a solid decomposes into solids, liquids and gases.

Chromium is denoted by the symbol Cr. It is a chemical element with atomic number 24.
The reaction between propanoic acid and ethylamine involves the formation of ammonium propanoate and water. The chemical equation for this reaction is: CH₃CH₂NH₂ + CH₃CH₂COOH → CH₃CH₂NH₃⁺CH₃CH₂COO⁻ + H₂O
chemical = chemies gear-mees, but with the g pronounced like ch in Loch Ness.
C4H19 Structurally it can be (CH3)2-CH-CH3
1. Pure natural gas (CH) doesn't smell. 2. Smell is a chemical property of substances because is caused by specific molecules.
The formula is CH3-COO-CH=CH2
