Answer:

of the Drain! What happens to rain after it falls? Rainwater, or snow melt, either soaks into the ground to become groundwater, evaporates, or flows over the surface of the land. The water that flows over the ground is called stormwater or runoff.

It either soaks up into the ground over time or precipitates because of the sun or it goes into the drain system which goes into the ground.

Given the following partial (valence-level) electron configurations,<br> (a) identify each element,

Kamila [148]

The arrangement of electrons within an atom is called the electronic configuration and the electrons are filled up according to the energy of the levels as: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f.

<h3>What is the difference between electron configuration and valence electron configuration?</h3>

Electron configuration is the number of electrons that are present in the atom and is repressed through the different sub-shells. So for example, the electron configuration for oxygen is 1s^2 2s^2 2p^4. While the valence electrons only refer to the electrons in the outermost shell of the atom.

<h3>What is a partial orbital diagram?</h3>

A partial orbital diagram shows only the highest energy sublevels being filled. Al (Z = 13) 1s22s22p63s23p1. A condensed electron configuration has the element symbol of the previous noble gas in square brackets. Al has the condensed configuration [Ne]3s23p1.

A set of headphones produces sounds that cancel out sound waves from the

Basile [38]

Answer:

C. Destructive interference

Explanation:

<em>Destructive interference</em> is when there are two waves <u>with the same frequency</u>, and the peaks of one wave (the highest points) line up with the valleys (the lowest points) of the second one.

Constructive interference would cause the sound to be louder.

Absorption and reflection are interactions that would not take into account the fact that the headphones produce sounds.

For a snack, I ate 40 gummy bears. Each gummy bear weighs 3g.

slega [8]

Taking into account the rule of three, you eat 480 kcal.

<h3>Rule of three</h3>

The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

That is, what is intended with it is to find the fourth term of a proportion knowing the other three.

If the relationship between the magnitudes is direct, the direct rule of three must be applied as follow, being a, b and c known data and x the variable to be calculated:

a ⇒ b

c ⇒ x

So: x= (c×b)÷ a

<h3>kcal of eaten gummy bears</h3>

To know the mass of eaten gummy bears, the following rule of three applies: if 1 gummy bear weighs 3 g, 40 gummy bears weigh how much mass?

1 gummy bear ⇒ 3 g

40 gummy bears ⇒ x

So: x= (40 gummy bears× 3 g)÷ 1 gummy bear

Solving:

If gummy bears are 100% carbohydrates and carbohydrates are 4 kcal/g, the following rule of three applies: If 1 g has 4 kcal, 120 g has how many kcal?

1 g ⇒ 4 kcal

120 g⇒ x

So: x= (120 g× 4 kcal)÷ 1 g

Solving:

In summary, you eat 480 kcal.
