Which substance can not be decomposed by ordinary chemical means?
compounds CAN be decomposed elements CANT
The answer would be Mercury because it is an element and can't be broken down by chemical means. but methane, ethanol and ammonia can be broken down by physical means because they are compounds.
An element is a material that cannot be decomposed into simpler substance by ordinary chemical means. This differs from compounds, which can be decomposed into the elements that make them. Read More
