Ice floats on water. For most other substances, however, the solid sinks in the liquid. Classify each of these statements based

sattari [20]

Answer:

1.High pressure will cause the liquid to become solid :

Describe both water and other substances

2.High pressure will cause the solid to become liquid :

It describe none : neither water nor other substances 

This statement is :False for both water and other substances

3.The solid is more dense than the liquid :

It describe other substance

This statement is :False for water but true for other substances.

4. In a phase diagram, the solid-liquid coexistence line has a negative slope.

It describes water:

This statement is :True for water because solid ice is less dense than liquid water.

False for other substance, they have positive slope

5.The molecules are closest in the liquid phase.

This statement is :False for water and other substances

6.The solid is less dense than the liquid:

It Describes water because ice is less dense than liquid water

7. In a phase diagram, the solid-liquid coexistence line has a positive slope.

It describe other substances

This statement is :True for other substances but false for water

8. The molecules are closest in the solid phase :

Describes both water and other substances

Explanation:

Answers to statement 1 , 2,5 and 8

Answers to statement 1 , 2

On increasing pressure and decreasing temperature , There occur Phase transition always for every substance :

From liquid to solid and gas to liquid

Hence,

In Both for water and other substance

High pressure will cause the liquid to become solid.

Answers to statement 5,8 :

2.The Particles of solid are closely packed hence there is maximum force of attraction between the particle of solid as compared to liquid and gases .

Hence , The molecules of both water and other substances are closest in the solid phase

This also means that in liquid molecules are far apart .

Rest statement : 3, 4 ,6 ,7 are explained below(see attached image)

The molecules are closest in the liquid phase is false statement and does not describe both water and other substance

Ice floats on water. For most other substances, however, the solid sinks in the liquid.

This can be explained using the phase diagram of water :

The line DB is = the solid-liquid coexistence line

It has negative slope because , solid ice is less dense than liquid water . That is why ice floats on water because its density is less than water

Hence Water is described truly by statement 4,6, which are :

4. the solid-liquid coexistence line has a negative slope.

6.The solid is less dense than the liquid.

Rest 3,7 = describe by other substance

other substance : Solid is more dense than the liquid ,the solid-liquid coexistence line has a positive slope

Describe how sediments are produced by weathering and erosion

TEA [102]

Weathering is the physical or chemical process where rocks are broken down to form sediments.
• Physical weathering does not change the rock’s composition.
• Chemical weathering does change the rock’s composition
• Erosion is the process where forces such as water, wind, ice, or gravity transport sediments to some remote location

Explain how different observations and experiments led to changes in the atomic model.

Bingel [31]

> Explain how different observations and experiments led to changes in the atomic model.

The atomic model has progressed over time. As scientists have learned more about the atoms, the atomic model has changed.

Democritus: first proposed that matter cannot be divided into smaller pieces

Dalton: created the 1st atomic theory. He viewed atoms as tiny solid balls

JJ Thomson: discovered electrons, he showed that atoms are made of even smaller things

Rutherford: discovered protons and nucleus, he showed that atoms have positive particles in the center and that atoms are made up mostly of empty space

Bohr: improved Rutherford’s model by proposing that electrons move around the nucleus in layers or shells

Chadwick: discovered neutrons = particles with no charge

The modern model of the atom is made up of works collaborated since 1920 which has electrons moving around the nucleus in a cloud.

> Explain how line spectra are used to identify elements and what they indicate about atoms.

Actually each element has its own unique spectra, hence this property can be used to identify the element. The line spectra give us an indication about the energy levels of the electrons, and each wavelength produces different colors.

> Represent electron arrangements using electron configuration, orbital notation, shorthand notation, and Lewis dot notation.

To answer your question, I will illustrate an example. The s orbital can accommodate 2 electrons, p orbital can accommodate 6, d orbital can accommodate 10, f orbital can accommodate 14. To take as example, Mg contains 12 electrons using the Aufbau principle, the electron configuration is: 1s2 2s2 2p6 3s2 the numbers after the letter represent the amount of electrons, the letters (s, p) represent the sublevel of the electron, while the number before the letter represent the principal quantum number, or "level".

Apply the rules and limitations of each quantum number to identify possible and impossible quantum number sets.

>There are four quantum numbers.

1. Principal quantum number (n) can take values of any positive whole numbers

2. Angular momentum quantum number (l) is from 0 to n – 1

3. Magnetic quantum number (ml) is from –l to +l

4. Spin quantum number (ms) only takes two values, positive spin and negative spin: +1/2, -1/2

From these rules you can identify possible and impossible set of quantum numbers.
