Solar radiation provides more heat and cleaner than near the pools on Earth the greatest amount of heat is moved away from the equator by
Answer:
Ocean Currents
Explanation:
The correct answer is Ocean currents.
When the earth receives solar radiation, a large fraction of this incident radiation is usually absorbed by the oceans and the seas, which become warm. Usually, equitorial regions are the ones that have this phenomenon. Now, when ocean currents are flowing from the equator, they usually carry this warm water with them thereby moving the greatest amount of heat from the equator on its way out.
For example, In the Pacific Ocean, there is a current known as Alaska Current that carries warm water in the northward direction thereby making Anchorage which is Alaska's largest city to have a much mild weather than the inland areas with the same latitude.

container has a volume of 28 L and a temperature of 45 ºC The volume is increased to 34 L. What is the new temperature of the gas
Answer:
386.14 K ( 113.14 ºC)
Explanation:
Initial Volume V1 = 28 L
Initial Temperature T1 = 45 + 273 = 318 K
Final Temperature T2 = ?
Final Volume V2 = 34 L
The relationship between these quantities is given by the charles law equation;
V1 / T1 = V2/ T2
T2 = V2 * T1 / V1
Inserting the values
T2 = 34 * 318 / 28
T2 = 386.14 K
The number of grams of sulfur in 223 grams of sodium sulfate is . . . Grams And explain how, I still dont get it fully
Answer:
50.25 g of sulphur, S.
Explanation:
Mass of Na₂SO₄ = 223 g
Mass of sulphur =?
Next we shall determine the molar mass of Na₂SO₄. This can be obtained as follow:
Molar mass of Na₂SO₄ = (23×2) + 32 + (16×4)
= 46 + 32 +64
= 142 g/mol
Mass of S in 142 g of Na₂SO₄ = 32 g
Finally, we shall determine the mass of S in 223 g of Na₂SO₄. This can be obtained as follow:
142 g of Na₂SO₄ contains 32 g of S.
Therefore, 223 g of Na₂SO₄ will contain = (223 × 32) / 142 = 50.25 g of S.
Thus, 223 g of sodium sulfate, Na₂SO₄ contains 50.25 g of sulphur, S.

How many molecules of calcium chloride are in 3CaCl2
An unknown solid has a specific heat capacity of 0.727 J/gC. If a 12.3 grams sample is heated and increases in temperature from 22.4C to 62.1C, calculate how much heat was absorbed? You must show your work.
I'm a little lost
Answer:
355Joules
Explanation:
The amount of heat absorbed can be calculated using the formula:
Q = m × c × ∆T
Where;
Q = amount of heat absorbed in joules
m = mass of substance in grams
c = specific heat capacity of solid (0.727 J/g°C)
∆T = final temperature - initial temperature (°C)
According to the information provided in this question;
Q = ?
m = 12.3g
∆T = 62.1°C - 22.4°C = 39.7°C
c = 0.727 J/g°C
Using Q = m × c × ∆T
Q = 12.3 × 0.727 × 39.7
Q = 355.001
Q = 355Joules
Hence, 355J of heat was absorbed

What is the mass of 3.25 moles of sodium hydroxide (NaOH)?
Answer:
1 mole is equal to 1 moles NaOH, or 39.99711 grams.
Explanation:
Hope this helps have a nice day :)
The statement of the mass of sodium hydroxide (NaOH) is "130 g."
What is mass?A substance is something to do with mass that takes up space. The mass of a compound is the total amount of atoms present in grams that make up a molecule. The grams is the unit of mass.
In order to determine the mass in grams, multiply moles of the substance value by its molar mass to convert moles into grams.
Mole to gram conversion factor,
[tex]=\;given \;mole\;.\;\frac{grams}{1\;mol}[/tex]
Mass of NaOH comes out to be,
[tex]=\;3.25\;mol\;.\;\frac{39.997\;g}{1\;mol}[/tex]
= 129.99 g
= 130 g
Hence the correct answer is 130 g.

A forest has both light colored trees and dark colored trees this same forest had both light colored months and dark colored months one year there is a disease that moves through the forest killing many of the light colored trees when the light colored trees were killed by a disease the forest became almost entirely composed of dark - colored trees generations later almost all months in the forest were dark in color instead of light which of the following gives the most likely explanation for why almost all the months were dark in color.
The dark moths were better hidden from predators and therefore more of them survived and this allowed them to have offspring.
Answer:
The dark moths were better hidden from predators and therefore more of them survived and this allowed them to have offspring.
Explanation:
If all of the light colored trees disappeared and there are only dark colored ones, then that means that the light colored moths wouldn't be able to live long since their traits wouldn't match the environment. This then leads to the conclusion that dark moths would be better hidden since their trait fits their current environment and would let them be hid much better from predators. This would allow them to survive longer and eventually, reproduce.

The methanol are produced when 2.8 grams of carbon monoxide reacts with 0.50 grams of hydrogen gas is 3.6 grams. option B is correct.
What is methanol?Methanol is also known as methyl alcohol or wood spirit, it is the long series of organic compounds called alcohols, having a methyl group (CH 3) attached with a hydroxy group (OH). Methanol was formerly made by the process of destructive distillation of wood.
Here, 2.8 grams of carbon monoxide reacts with 0.50 grams of hydrogen gas as there are 4 hydrogen molecules add 2.8 + 0.50 × 2 = 3.6 grams.
Therefore, methanol are produced when 2.8 grams of carbon monoxide reacts with 0.50 grams of hydrogen gas is 3.6 grams. option B is correct.
