The atomic mass can be defined as the mass of neutrons and protons in the atom. The atomic mass of the oxygen isotope is 18 amu.
<h3>What is an atom?</h3>
An atom is the smallest particle comprised of three subatomic units, namely electrons, protons, and neutrons.
The number of electrons in the atoms determines the atomic number, while the number of protons and neutrons determines the atomic mass.
The atomic mass can be given as:
The oxygen isotope has been comprised of 10 neutrons and 8 protons. The atomic mass of the isotope is given as:
The atomic mass of the oxygen isotope is 18 amu. Thus, option C is correct.

Answer: Option (d) is the correct answer.
Explanation:
During a lightening strike, when an individual is in a house 8 miles away then he will be safe.
This is because house is a closed shelter so lightening cannot enter inside the house unless and until the windows or doors are open.
Whereas a tent cannot be safe during lightening strike as tent is made up of cloth or light weight material. Hence, it does not provide any protection during lightening strike.
On the other hand, a person standing 8 miles away or a person on a bike 8 miles away is not safe as both bike and ground are conducting in nature. So, it may lead to death if lightening strikes on it.
Answer:
0.25 moles
Explanation:
The molar mass of NaOH is 40 g/mol.
This equals 0.25 moles
Hydrophobic means "water fearing" while polar molecules are hydrophilic meaning "water loving." Hydrophobic exclusion describes the tendency, for examples, of multiple oil droplets in water to coalesce into fewer, larger droplets
Answer:
An another result of climate change is the increasing in the frequency of high intensity rainfall events,which increase the regional water damage events.If the precipitation volume decreases in summer time and increases in winter time,then it will be lower infiltration and more runoffs.
