Answer:
Oxygen in heavy water, or d20, have an extra neutron, and it contains a higher portion of hydrogen. The extra neutron makes d20 (heavy water) about 10% denser than normal H20 (water).

Answer: Government regulation, healthcare, telemarketing, environmental engineering, banking.
Explanation:
Science is the set of objective and verifiable information about all areas of human knowledge. To create knowledge, science uses the scientific method, this method explains, formulates and verifies a hypothesis about a concept.
Science can be used in all professional fields because it allows for obtaining objective information or knowledge. For example, in government regulation, the scientific method can be implemented to make objective decisions about decisions that will best help the population.
I hope this information can help you.
In a chemical bonding the electrons that are in the outer most orbital are the one's involved in bonding. The aim of bonding is that each of the atoms must have an octet of electons ( but there are exception which do not follow this rule ) in their valence orbital in order to become stable.Atoms can either loses, gain or share electrons in order to reach this desired state. In a case where they share, they might share all their valence electrons either with the same or different atoms or a certain number of their electron which will end up with them having eight electrons in their valence orbital. Once the atoms have bonded, the remaining electrons that are not shared between the atoms are called the unshared elctron pair and the electrons that are shared and involved in forming bonds are called the shared electron pair. the unshared electron pair can be shared with another atom that has lost it's electrons, this pair is then called a lone pair.
