The substance with the highest mass is botulinum toxin
Nonmetals form negatively charged ions, or anions. They do this because they need to gain one to three electrons in order to achieve an octet of valence electrons, making them isoelectronic with the noble gas at the end of the period to which they belong.
<span>At STP 1 mol of an ideal gas has a volume of 22.4 L.
We assume (from the question) that the methane has an ideal behavior.
Hence if 1 mole of an ideal gas ccupies a volume of 22.4 L
Then 0.75 mole occupies X
Hence X * 1 = 0.75 * 22.4
X = 16.8L</span>
A few elements with 1 valence electron are hydrogen (H), Lithium (Li), and sodium (Na)
Hydrocarbons are only made up of carbon and hydrogen. since this compound has chlorine, it is not a hydrocarbon
