Electrons spin in shells around the nucleus. The closest shell (n = 1) can contain a maximum of _____ electrons?

Answers

Answer 1

Answer:

The given blank can be filled with two electrons.

The K, L, M, N are the four shells in an atom. The K shell is the initial that is present nearest to the nucleus of the atom, and it comprises two electrons. The L shell can withstand eight electrons, M shell can withstand eighteen electrons, and however, the atom attains stability if the last (valence) shell comprises eight electrons.

Answer 2

Answer: Electrons spin in shells around the nucleus. The closest shell (n = 1) can contain a maximum of 2 electrons.

Consider this reaction:PCl5(g) + heat PCl3 (g) + Cl2 (g)
What will happen when the pressure is decreased?
There will not be a shift in equilibrium.
There will be a shift toward the products.
There will be a shift toward the reactants.
There is not enough information to make a prediction.

Answers

The answer is There will be a shift toward the products.

To solve this problem, it is necessary to understand Le Chatelier's principle. According to the principle, if a chemical reaction undergoes changes in conditions, the chemical equilibrium will shift in order to undo the effects. In the reaction PCl5(g) + heat ↔ PCl3 (g) + Cl2 (g), when pressure is decreased, the system will try to increase it. This will result in the increase of gaseous pressure, so the equilibrium will be shifted toward the products.

Using the explicit formula, calculate how far the students will be swimming on week 10 using Ernest's schedule.

Answers

Ernest would be swimming at 3.25 units on week 10

The explicit formula is given as:

$a_n = a_1 + (n - 1) * d$

Also, we have the following parameters

$a_1 =1.0$ -- the initial distance

$d =0.25$ --- the difference between concurrent distances

In week 10, the value of n is 10.

Next, substitute 10 for n in the explicit formula $a_n = a_1 + (n - 1) * d$

So, we have:

$a_(10) = 1.0 + (10 - 1) * 0.25$

Subtract 1 from 10

$a_(10) = 1.0 + 9 * 0.25$

Multiply 9 by 0.25

$a_(10) = 1.0 + 2.25$

Add 1.0 and 2.25

$a_(10) = 3.25$

Hence, Ernest would be swimming at 3.25 units on week 10

Answers

The correct answer to the question above is cytoskeleton. Microtubules, microfilaments, and intermediate filaments make up the cytoskeleton, which lies beneath the plasma membrane and provides support, movement, and shape for the cell. These structures definitely form cytoskeleton for the support and structure.
