How many electrons does the 2nd main energy level hold when it is full?

Chemistry
1 answer:
UNO [17]3 years ago
5 0

Answer:

8 electrons

Each principal energy level can contain up to 2n2 electrons, where n is the number of the level. Thus, the first level can contain up to 2 electrons, 2(12) = 2; the second up to 8 electrons, 2(22) = 8; the third up to 18, 2(32) = 18; and so on.

How many grams are in 36.2 moles of Iron (I) fluoride?
Allushta [10]

Answer:

4084.808 grams (SigFigs: 4085 grams)

Explanation:

The molar mass of Iron fluoride is 112.84 g/mol.

To calculate the mass, multiply the molar mass by the number of moles.

36.2 mol * 112.84 g/mol = 4084.808 g

Convert to Sigfigs (if necessary):

4085 g

wariber [46]

Answer:

New volume = 8.00 Liters

Explanation:

Boyles Law => P₁V₁ = P₂V₂

P₁ = 1.0 Atm

V₁ = 20.0 L

P₂ = 2.5 Atm

V₂ = ?

P₁V₁ = P₂V₂ = V₂ = V₁(P₁/P₂) = 20.0L(1.0Atm/2.5Atm) = 8.00L

Describe the three main types of plate boundary interactions:
bulgar [2K]

Answer:

In the explanation

Explanation:

Divergent: When two plates are diverging from each other, meaning that the two plates are moving away from each other. Events that may occur include ridges or rifts.

Convergent: When two plates are moving towards each other.

If a continental plate and an oceanic plate are converging, the oceanic plate would slide underneath the continental plate since it is thinner. This would result in subduction, which means that part of the oceanic plate would hang underneath the continental plate, where magma can melt the hanging part.

If two continental plates are converging, the crash would result in mountains or volcanic activity. Magma could rise and rush from the crack. There would be a bump in these tectonic plates.

Transform: When two plates are sliding past each other. Earthquakes can occur when the plates are sliding. When an oceanic plate is involved, the movement of the plates could cause a tsunami as well. The water above the transform fault could rise, and grow bigger and bigger. The 2011 Japan Tsunami is a good example of this.

Hope this helps!
