Answer:
D. 27.099 x 10²³.
Explanation:
- It is known that every 1.0 mole of an atom contains Avogadro's no. (6.022 x 10²³) atoms.
<em>So, 4.5 mol of Hg will contain:</em>
(4.5 mol)(6.022 x 10²³) = 27.099 x 10²³ atoms.
<em>So, the right choice is: D. 27.099 x 10²³.</em>
Answer: Heyo Kenji Here! Here's your answer- when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.

His revisions proved the importance of the atomic number and acknowledged why some of the elements seemed like they were out of place, even though they were in the right place.
Answer:
element
Explanation:
an element is something made up of only one type of atom
Answer:
Constitutional isomers vs stereoisomers
Structural (constitutional) isomers have the same molecular formula but a different bonding arrangement among the atoms. Stereoisomers have identical molecular formulas and arrangements of atoms. They differ from each other only in the spatial orientation of groups in the molecule.
