Dovator [93]

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 Increases because Z increases from 5 to 6 , The thickness of the frosting stays the same because the core electron configuration is the same for both atoms

Part B

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

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 $[Ne]\ 3s^2 \ 3p^1$

Which statement best describes the work and energy in these examples?

solniwko [45]

Answer: Option A: The gas and food are examples of energy.

Explanation:

Work and energy are inter-related. Energy is required to do the work. An equal amount of energy is converted into work. Work and energy have same units. The SI unit is Joule.

The gas and food are sources of energy. They act as fuel. This energy is utilized to perform work. The gas is used to run the car. The food is metabolized inside the body which is a source of energy and utilized to perform every day work.

Hence, The gas and food are examples of energy.
