Answer:
1.High pressure will cause the liquid to become solid :
<u>Describe both water and other substances</u>
2.High pressure will cause the solid to become liquid <u>:</u>
<u>It describe none : neither water nor other substances </u>
<u>This statement is :False for both water and other substances</u>
3.The solid is more dense than the liquid :
It describe other substance
<u>This statement is :False for water but true for other substances.</u>
4. In a phase diagram, the solid-liquid coexistence line has a negative slope.
It describes water:
<u>This statement is :True for water because solid ice is less dense than liquid water.</u>
<u>False for other substance, they have positive slope</u>
5.The molecules are closest in the liquid phase.
<u>This statement is :False for water and other substances </u>
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
<u>This statement is :True for other substances but false for water</u>
8. The molecules are closest in the solid phase :
<u>Describes both water and other substances </u>
Explanation:
<u>Answers to statement 1 , 2,5 and 8</u>
<u>Answers to statement 1 , 2</u>
On increasing pressure and decreasing temperature , There occur<u> Phase transition</u> always for every substance :
From liquid to solid and gas to liquid
Hence,
In Both for water and other substance
<u>High pressure will cause the liquid to become solid.</u>
<u>Answers to statement 5,8 :</u>
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 <u>of both water and other substance</u>s 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)
<u>The molecules are closest in the liquid phase is false statement and does not describe both water and other substance</u>
<u>Ice floats on water. For most other substances, however, the solid sinks in the liquid.</u>
This can be explained using the phase diagram of <u>water </u>:
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 <u>Water is described truly by statement 4,6, </u>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
<u>other substance</u> : Solid is more dense than the liquid ,the solid-liquid coexistence line has a positive slope
The question is incomplete, complete question is :
In an organic structure, you can classify each of the carbons as follows: Primary carbon (1°) = carbon bonded to just 1 other carbon group Secondary carbon (2°) = carbon bonded to 2 other carbon groups Tertiary carbon (3°) = carbon bonded to 3 other carbon groups Quaternary carbon (4°) = carbon bonded to 4 other carbon groups How many carbons of each classification are in the structure below? How many total carbons are in the structure? How many primary carbons are in the structure? How many secondary carbons are in the structure? How many tertiary carbons are in the structure? How many quaternary carbons are in the structure?
Structure is given in an image?
Answer:
There are 10 carbon atoms in the given structures out of which 6 are 1° , 1 is 2° , 2 are 3° and 1 is 4°.
Explanation:
Total numbers of carbon = 10
Number of primary carbons that is carbon joined to just single carbon atom = 6
Number of secondary carbons that is carbon joined to two carbon atoms = 1
Number of tertiary carbons that is carbon joined to three carbon atoms = 2
Number of quartenary carbons that is carbon joined to four carbon atoms = 1
So, there are 10 carbon atoms in the given structures out of which 6 are 1° , 1 is 2° , 2 are 3° and 1 is 4°.
