Answer:
B.111
Explanation:
Atomic mass = number of protons(or atomic number) + number of neutrons
186 = 75 + number of neutrons
number of neutrons = 186 -75 = 111
Answer:
Land and sea breeze
Explanation:
This uneven warming of the land during the day results in the phenomenon called land and sea breeze.
- During the day, the land heats up faster than the nearby ocean.
- Ocean is made up of water with a high specific heat capacity.
- This derives pressurized air near the surface of the land to the ocean.
- At night, the ocean does not easily lose heat after the land has lost its own.
- Pressurized air moves from the ocean to the land.
- This causes the warming of the land during the night.
The atomic number of an atom is the number of protons. The atomic mass is the sum of the protons and neutrons and the net charge is the difference between the number of protons which have positive charges, and electrons, which have negative charges
