4, 3, 1

Explanation:

Sb has four on the right, so it needs four on the left. It's all alone, so <u>4</u>.

O2 comes in pairs, so you only need <u>3</u> of those to get six oxygens.

And 1 is the place holder for the right side since we got the left to match perfectly.

Levart [38]

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.

Why sulphur has two melting point values

Fofino [41]

I don't know how well known/accepted this is (it's in my textbook so I'm guessing it's right), but Sulphur has two forms - the alpha and beta forms ,apparently gamma sulphur exists as well.

The alpha form is rhombic, yellow in color and has a MP of 385.8 K. The beta form is colorless and has a MP of 393 K and is formed by melting rhombic sulphur and cooling it till a crust forms on top. Poke a hole and pour out the liquid inside and you get beta sulphur. The transition point is 369K - below it, alpha sulphur is stable and above it, beta sulphur is stable. Both have helped. I had to pull out an old textbook and that's something that I don't usually do.

Calculate the ph of a solution in which [oh–] = 4.5 × 10–9m.

frosja888 [35]

pOH = -LOG([OH])

pOH = -LOG(4.5*10^-9)

pOH = 8.34

pH + pOH = 14

pH = 14 - 8.34 = 5.65

hope this helps!
