Answer:

Can u gimme brainliest?

Explanation:

They are called spheres because they are round, just like the Earth. The four spheres are the geosphere (all the rock on Earth), hydrosphere (all the water on Earth), atmosphere (all the gases surrounding Earth), and biosphere (all the living things on Earth).

If I have a +2 oxidation number do I give up or accept electrons?​
sveticcg [70]

Answer:

Give up 2 electrons.

Explanation:

Is this ever a good question!!!

Electrons have a minus charge

Protons have a plus charge.

You need to understand it thoroughly.  I used to explain it this way.

Suppose the protons and electrons are playing a game and the electrons commit a foul that leaves them with 2 men short.

That means there are 2 unguarded plus's around. The result is that the minuses have lost two men who are in the sin bin. (I watch a lot of hockey).

So a +2 means that the electrons have lost two of their players to penalties.

Put in the vocabulary of your question, you give up 2 electrons.

Write the following numbers in ordinary notation.
adoni [48]

Answer:

Explanation:

The values are given in scientific notation.

Scientific notation:

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

. The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³

Ordinary notation:

The ordinary notation is expended notation of writing the numerical values which is normal way. The numbers are written as they are, without the power of 10.

a) 7.356 ×10⁻⁶ km

0.000007356 km

b) 3.02 ×10⁻⁵ g

0.0000302 g

c) 8.348 ×10⁶ Kg

8,348,000 kg

d) 7.6352 ×10⁻³ s

0.0076352 s

Why does it take more energy to evaporate water than to melt ice?
DaniilM [7]

Answer:

The energy required to completely separate the molecules, moving from liquid to gas, is much greater that if you were just to reduce their separation, solid to liquid. Hence the reason why the latent heat of vaporization is greater that the latent heat of fusion.
