Radon is a naturally occurring radioactive gas. It comes from radioactive decay of uranium.
It is usually found in igneous rock and soil, but in some cases, well water can also be a source of radon.
Answer:
Covalent network solids are formed by networks or chains of atoms or molecules held together by covalent bonds. Consists of sp3 hybridized carbon atoms, each bonded to four other carbon atoms in a tetrahedral array to create a giant network. Examples of network covalent solids include diamond and graphite (both allotropes of carbon), and the chemical compounds silicon carbide and boron-carbide.
Visible light spectrum or electromagnetic spectrum
The larger the piece the longer it will take to break down. This is because it has more mass that needs to be broken down.
Answer:
C. the relative molecular mass of the compound
Explanation:
Like molecular formulas, empirical formulas are not unique and can describe a number of different chemical structures or isomers. <u>To determine an empirical formula, the relative molecular mass of the composition of its elements</u> can be used to mathematically determine their ratio.
