Answer:

Absorbs.

Explanation:

Hello,

In this case, we consider that sunlight makes up of a mix of all visible wavelengths of electromagnetic spectrum. It has been substantiated that when all visible wavelengths get into the eye at once, the color white is perceived. However, the absence of any light is related with the black color.

In such a way, black it is said to absorb the radiation while white reflects it, therefore, when the sun is shining, providing high temperatures, it is recommended to wear light colored T-shirts.

Therefore, the answer is:

"It was field day at school. The sun was bright and the temperature high. Most of the students wore light colored T-shirts to stay cool because dark colors absorbs most wavelengths found in white light."

Best regards.

What is the transfer of electrons in Al + Cl = AlCl3
otez555 [7]

Answer:

3 e⁻ transfer has occurred.

Explanation

This is a redox reaction.

  • Oxidation (loss of electrons or increase in the oxidation state of entity)
  • Reduction (gain of electrons or decrease in the oxidation state of the entity)
  • An element undergoes oxidation or reduction in order to achieve a stable configuration. It can be an octet or duplet configuration. An octet configuration is that of outer shell configuration of noble gas.
  • [Ne]= (1s²) (2s² 2p⁶)

A combination of both the reactions( Half-reactions) leads to a redox reaction.

Let us look at initial configurations of Al and Cl

[Al]= 1s² 2s² 2p⁶ 3s² 3p¹

[Cl]= 1s² 2s² 2p⁶ 3s² 3p⁵

Hence, Al can lose 3 electrons to achieve octet config.

and, Cl can gain 1e to achieve nearest noble gas config. [Ar]

This reaction can be rewritten, by clearly mentioning the oxidation states of all the entities involved.

Al⁰ + Cl⁰ → (Al⁺³)(Cl⁻)₃

Here, Aluminum is undergoing an oxidation(i.e loss of electrons) from: 0→(+3)

Chlorine undergoes a reduction half reaction (i.e gain of electrons) from: 0→(-1). There are 3 such chlorine atoms, hence 3 e⁻ transfer has occurred.

What force is causing The object to eventually stop moving
hichkok12 [17]

Answer:

Hey buddy, here is your answer. Hope it helps you.

Explanation:

The force stopping the object's motion might be an obvious one - the ground! Friction is a force that slows or stops motion. Friction is the resistance to motion created by two objects rubbing against each other (the sled and the snow, for instance). Even air causes friction.

Analyze the bonds of CCl4. What is the shape of the CCl4 molecule? Is it symmetrical? Does this mean that the CCl4 molecule is p
Crank

C-Cl bond is polar.


As Cl is more electronegative than C,  

Cl pulls the shared electrons towards its side making the C-Cl bond polar.


Polar meaning C gets a partial positive charge and Cl gets a partial negative charge. Thus C-Cl bond becomes polar.


CCl4 molecule is tetrahedral.

And its shape is symmetrical.


That means its similar on all corners or all planes and it can be cut into equal halves from any plane.


C-Cl bond is polar.But the C-Cl polairty gets cancelled out as its pulled equally from all sides.


Since the molecule is symmetrical CCl4 is non polar.
