B) convection
Explanation:
Once the sun's energy reaches the earth's atmosphere by radiation, it is circulated within the atmosphere and oceans through convection.
The energy of the sun on earth is moved between the ocean and the atmosphere by air around us.
- Heat transfer in fluids is by convection.
- It involves the actual motion of the particles of medium from one place to another due to differences in temperature and density.
- Air close to the surface of the ocean is less dense and hot due to high temperature.
- The air rises and it is replaced by colder air masses.
- This exchange leads to the development of convective cells.
- This moves the energy of the sun between the atmosphere and the ocean surface.

Answer:
Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure
Explanation:
The configuration of these elements is as follows;
Cl₁₇ = 2, 8,7 (the outer electron is 7)
Ca₂₀ = 2,8,8,2 (the outer electron is 2)
Ne₁₀ = 2,8 (the outer electron is 8)
Na₁₁ = 2,8,1 (the outer electron is 1)
Based on the outer electron value above, Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure.
Answer:
0.465
Explanation:
To find the volume of a substance, divide the mass by the density.
M/D = V
10.0 / 21.5 = 0.4651163
Then round to 3 significant figures: and the density is 0.465
Answer:
Ionic compounds have a metal and nonmetal.
Ionic compounds are made up of ions.
Explanation:
You did not provide any formulas for me to correct, but:
- ionic compounds tend to have metals and nonmetals. (EX: NaCl)You can look at the periodic table to see which elements are metals and which are not.
- ionic compounds are made up of ions. Ions are elements that have a charge (Like
or 
). To have a correct ionic compound, make sure that the ions inside of it "cancel" each other out.
EX: Na has a +1 charge. Cl has a -1 charge. When they are paired up, they successfully cancel each other out (become neutral) and become the ionic compound NaCl.
The chart below shows you the charge of each element. Make sure the charge of the elements in an ionic compound "cancel" each other out.
The very last chart shows the metals and nonmetals
