Complete Question

The complete Question is shown on the first and second uploaded image

Answer:

The underlined words are the answers

Part A

Moving from boron to carbon, the intensity of the bulb <u>Increases</u> because Z increases from <u>5</u> to <u>6</u> , The thickness of the frosting <u>stays the same </u> because the core electron configuration is the same for both atoms

Part B

Moving from boron to aluminum the intensity of the bulb <u>Increases</u> because Z increases from <u>5</u> to <u>13</u> . The thickness of the frosting also <u>increases</u> because Al has the core configuration of <u>Ne</u>, while B has the core configuration of <u>He</u>

Explanation:

Here Z denotes the atomic number

Ne denoted the element called Neon and its electronic configuration is

$1s^2 \ 2s^2 \ 2p^6$

He denoted the element called Helium and its electronic configuration is

$1s^2$

B denoted the element called Boron and its electronic configuration is

$1s^2 \ 2s^2\ 2p^1$

Looking at its electronic configuration we can see that the core is He

I,e $[He]\ 2s^2 2p^1$

Al denoted the element called Aluminium and its electronic configuration is

$1s^2 \ 2s^2 \ 2p^2 \ 3s^2 \ 3p^1$

Looking at its electronic configuration we can see that the core is Ne

I,e $[Ne]\ 3s^2 \ 3p^1$

A super ball is dropped from a height of 100 feet. Each time it bounces, it rebounds half the distance it falls. How many feet w

Crank

The total distance travelled by the ball after the fourth impact is 275 feet.

<u>Explanation:</u>

Given-

Height, h = 100 feet

Rebounds half the distance

Distance in feet for the fourth time, x = ?

For the first time, the distance travelled by the ball is, x = 100 feet

For the second time, it will bounce up to 50 feet and fall upto 50 feet( half of 100 feet)

So, the distance travelled after the second impact, x = 100 + 50 + 50 = 200 feet

For the third time, it will bounce up to 25 feet and fall upto 25 feet( half of 50 feet)

So, the distance travelled after the third impact, x = 200 + 25 + 25 = 250 feet

For the fourth time, it will bounce up to 12.5 feet and fall upto 12.5 feet( half of 25 feet)

So, the distance travelled after the fourth impact, x = 250 + 12.5 + 12.5 = 275 feet

Therefore, total distance travelled by the ball after the fourth impact is 275 feet.

Lines of a particular element appear at the same wavelength in both emission and absorption line spectra. True or False

Liula [17]

<h2>Answer: True </h2><h2></h2>

Each atom emits or absors electromagnetic radiation, but only in some frequencies that are characteristic of its chemical element.

Now, if we supply energy in the form of heat (thermal energy) to a certain element in its gas phase, this will be stimulated and its atoms will emit radiation in certain frequencies of the visible spectrum, which constitute its <u>emission spectrum</u>.

If the same element, also in gaseous state, receives electromagnetic radiation, it absorbs in certain frequencies of the visible spectrum, <u>precisely the same ones in which it emits when it is stimulated by heat</u>. This will be its <u>absorption spectrum.</u>

<h2>This means that every element absorbs radiation in the same wavelengths in which it emits it. </h2>

Which term describes the point when two objects reach the same temperature and there is no longer a transfer of energy through h

yaroslaw [1]

The term you need to know is equilibrium. Technically it means that heat gained = heat lost. Normally in beginning chemistry classes the evidence for this condition is a stable temperature.
