Answer:

C. 3

Explanation:

If you look at aluminum (Al) in the Periodic Table of the Elements, you will see that its electron configuration is 2-8-3.  The last number indicates the valence shell, which contains three electrons.

The answer is (3) 3. The outer shell of an atom is called valence shell. And the ground state is the lowest energy state of an atom. Aluminum has a electron distribution of 2, 8, 3. So the outer shell has 3 electrons.

What is the indicator of the number of ions in solution?
Andru [333]

Answer:

The amount of solute added.

Explanation:

The amount of solute added is directly proportional to the number of ions.

The higher the amount added the higher the number of moles.

The number of moles is multiplied by the Avogadro's constant to get the number ions.

No of ions= No of moles × L

L is the Avogadro's number.

Natasha_Volkova [10]

Answer:

17.04%

Explanation:

Actual Value = 173.1

Measured Value = 143.6

Percent error is obtained using the equation;

Percent error = (Measured - Actual) / Actual ]* 100

Percent error = [ (143.6 - 173.1) / 173.1 ] * 100

The absolute value of (Measured - Actual) is taken,

Percent Error = [29.5 / 173.1 ] * 100

Percent Error = 0.1704 * 100 = 17.04%

The atmosphere's variable gases that most influence the greenhouse effect are _____. nitrogen and oxygen argon and carbon dioxid
Katena32 [7]
The correct answer is carbon dioxide and water vapor

These negative gasses get modified and then remain in the atmosphere without the possibility of leaving, which is why the greenhouse effect occurs.

Which option accurately describes the first two stages of photosynthesis?
Lemur [1.5K]

Answer;

A) Stage 1: Chlorophyll captures light energy. Stage 2: Light energy is converted to chemical energy.

Explanation;

-Photosynthesis is the process by which green plants use energy from the sun, water and carbon dioxide to make organic compounds such as simple sugars together with release of oxygen.

-The process occurs in tow stages; light-dependent stage and light independent stage. During light dependent stage, chlorophyll absorbs sunlight and uses it to split water molecules into hydrogen ions and oxygen atoms. In the light independent stage carbon (iv) dioxide is fixed and the result is organic compound; the light energy is converted to chemical energy.
