Answer:
A
Explanation:
First there is molecular size. Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules. ... Molecular shape is also important, as the second group of compounds illustrate.
Most halogens form compounds by gaining an electron to form a negative ion
Combined gas law comes from the combination of Boyle’s law, Charles law and Gay Lussac’s law. Accordingly to Boyle’s law, at constant temperature, pressure of gas is inversely proportional to its volume
Answer:
D is the answer
Explanation:
<h2>This is because the mole is the unit of amount in chemistry. ... A mole of a substance is defined as: The mass of substance containing the same number of fundamental units as there are atoms in exactly 12.000 g of 12C. Fundamental units may be atoms, molecules, or formula units, depending on the substance concerned and the proportional should be put into so the values can come out in specifc liter.</h2>
