Answer: reflected, clouds, greenhouse effect.
Explanation:
Sunlight can be absorbed, reflected , or scattered before it reaches Earth’s surface. About 30 percent of sunlight hits Earth directly, and 22 percent is filtered through clouds . Dust particles scatter short wavelengths, which causes the sky to appear blue. Earth radiates heat into the atmosphere, which traps the heat in gases, causing the greenhouse effect.
Answer:
The sun is our main source of heat and light energy. A source is where something comes from. The heat we feel and the light we see here on Earth is mainly from our nearest star, the sun.
Explanation:
B. 3.0 mol·L⁻¹ NaCl
Explanation:
Freezing point is a colligative property: it depends only on the number of particles in solution.
The for freezing point depression ΔT_f is
ΔT_f = iK_fb
where
i = the number of moles of particles available from one mole of solute
K_f = the molal freezing point depression constant
b = the molal concentration of the solute
All your solutions are aqueous NaCl. They differ only in their concentrations.
Thus, the most concentrated solution will have the greatest freezing point depression and the lowest freezing point.

Explanation:
Empirical correlation based on the work of Bridgwater and Mumford (1979):
For Liquid or solid phase Plants:
F<60,000 tonne/yr Eq (1)
F≥60,000 tonnes/yr Eq (2)
Where:
N is the number of functional units
F is the process throughput tonnes/yr
In our case F=40,000 tonne/yr <60,000 tonne/yr, We are going to use Eq (1)
F<60,000 tonne/yr
N=8, F=40,000 tonne/yr

Answer:
The answer to your question is: letter C
Explanation:
Chemical properties is a change is matter observed due to a chemical reaction.
A) Water is a polar molecule. This is a physical property, there is no chemical reaction. This option is wrong.
B) Water is the universal solvent. This is a physical property of water, there is no change of matter, so this is not a chemical property.
C) Water reacts with group 1 metals. This is an example of a chemical property because metals react with water and matter changes to a new substance, this is the correct answer.
D) Water has a high specific heat capacity. This is a physical property, it is not the correct answer to the question.
