The organic compounds which consist of single bonded carbon and hydrogen atoms are called alkanes. They are also called the saturated hydrocarbons. Here the given alkane is propylcyclopentane. The correct option is A.
What is propylcyclopentane?The propylcyclopentane is an alkane which is the simplest family of hydrocarbons. It is a cyclic hydrocarbon which acts as the major component of gasoline and it is also used in the manufacture of synthetic resins and rubber adhesives.
The propylcyclopentane is an important cycloalkane which contains five carbon atoms bonded to two hydrogen atoms above and below the plane. It appears as a clear colourless liquid with a petroleum like odor. It is less dense than water and it is insoluble in water.
Propylcyclopentane is a member of cyclopentanes, a cycloalkane and a volatile organic compound. Its molecular formula is C₈H₁₆. It can also be called as 1 - Cyclopentylpropane.
Thus the correct option is A.

At a certain grocery store a 0.500 pound container of ground cinnamon cost $6.98 (excluding tax). Cinnamon has a density of 0.560 g/Ml. How much would 500.0 mL of cinnamon cost?
Answer:
The cinnamon cost would be "$8.62". A further explanation is given below.
Explanation:
Cinnamon's density,
= 0.560 g/ml
On converting it into g, we get
= [tex]0.560\times 500[/tex]
= [tex]280 \ g[/tex]
Cinnamon's volume,
= 500 ml
As we know,
1 pound = 435.592 g
Now,
The cost pf cinnamon per pound will be:
= [tex]\frac{6.98}{0.5 \ pound}[/tex]
= [tex]13.96[/tex] ($) per pound
So,
Cinnamon's cost will be:
= [tex]250 \ g\times \frac{1 \ pound}{435.592 \ g}\times \frac{13.96}{1 \ pound}[/tex]
= [tex]8.62[/tex] ($)

How can you tell if an ion is a polyatomic ion if all you have is the name?
I can't seem to figure this out! Please help me out!

Answer:
All the elements on the periodic table start with a capital letter and only some of them have a second letter that is lower case. So if you see two capital letters together in a ion then you will know that it is a polyatomic.

Oday, you will observe drops of liquid water and compare them to drops of liquid isopropanol, noting whether either liquid evaporates. Given that the energy transferred in from the air will be the same for both liquids, make a prediction about whether both drops or only one drop will evaporate within five minutes. Explain your prediction below.
Answer:
Liquid isopropanol.
Explanation:
Liquid isopropanol will evaporate earlier than water because the boiling point of isopropanol is less than water. That liquid which have high boiling point require more heat energy for change into vapor state as compared to those liquids that has low boiling point. The isopropanol has boiling point i.e. 82.5 °C while on the other hand, water has boiling point i.e. 100 °C so we can say that isopropanol will evaporate first.
The liquid that will be the first to evaporate within 5 minutes is; Liquid Isopropanol
We have the 2 liquids as;
Liquid Isopropanol
Liquid water
Now, since we are dealing with the one that will evaporate within five minutes, we need to know their boiling points.
From online research;
Boiling point of liquid isopropanol is 82.5°C
Boiling point of liquid water is 100°C
Now, we are told that the same energy is transferred for both liquids. However, boiling point of the liquid with the lower boiling point will be achieved first and as a result will evaporate first since the next stage after boiling point is evaporation of steam.

An intravenous solution of mannitol is used as a diuretic to increase the loss of sodium and chloride by a patient. If a patient receives 30.0 mL of 25% (m/v) mannitol solution, how many grams of mannitol were given?
Answer:
Explanation:
25 % ( m / v ) mannitol solution means 25 gram in 100 cc of water
25 gram in 100 mL of water
grams of mannitol in 30 mL = 25 x 30 / 100
= 7.5 grams .

As a scuba diving air tank is filled with air, the air is compressed in the tank to as much as 3000 psi of pressure. When filling the tank, it is observed that the tank becomes warmer.
Which argument BEST explains why this occurs?
A
When air is compressed, it turns solid. A short time later, the air evaporates back into a gas which releases heat.
B
When air is compressed, the molecules line up into a crystalline structure. As the molecules line up, they release energy in the form of heat.
C
When air is put into the tank, it expands rapidly, thereby raising the temperature.
D
Air molecules are free to move and as more air is added to the tank, the molecules move and collide faster which raises the temperature.
Answer:
The gas under pressure subjected to heat can cause the tank to explode. A scuba tank filled to capacity with compressed air at 3000 psi could just as easily go up to 3400-3500 psi if heated
Explanation:
Air molecules are free to move and as more air is added to the tank, the molecules move and collide faster which raises the temperature. Hence option D is correct.
What is pressure?Pressure is defined as the force applied perpendicularly to an object's surface divided by the surface area over which it is applied. The movement of the molecules and the collisions they have with one another and the vessel walls cause the pressure to build up. According to general relativity theory, pressure contributes to the mass-energy cause of gravity by making a gravitational field stronger.
The tank may blow up if the gas within was under pressure and exposed to heat. If heated, the pressure of a scuba tank filled to capacity with compressed air at 3000 psi may readily increase to 3400-3500 psi. Because air molecules are free to move, the temperature in the tank rises as more air is introduced, as the molecules move and collide more quickly.
Thus, air molecules are free to move and as more air is added to the tank, the molecules move and collide faster which raises the temperature. Hence option D is correct.

Explanation:
Ideal gas particles do not interact with each other.
The gas molecules do not interact with each other except for colliding with each other. Gases expand to completely fill a container; they would not if they were attracted to each other. That being said, they obviously still do, as a result of Dalton's Law.

what is the SI unit that represents the amount of substance?
Answer:
Mole
Explanation:
In solids, amount of substance is given by;
n = mass/molar mass
n will have a unit of mole
However, in liquids, amount of substance is;
n = concentration × volume
Again, n will be in mole
Thus, the SI unit that represents the amount of substance is mole

1 & 2 ,
2 & 3
1 & 3
2 & 4
Answer:
1 & 3
Explanation:
Elements have similar chemical and physical properties if and only if they belong to the same group of elements in the periodic table.
A group of elements in the periodic table is a family of elements, the elements in the in the same group have the same number of valence electrons in their outermost shell, share similar chemical reactivity (with slight variation within the group) and similar physical properties (with slight variation within the group).
Magnesium, radium, beryllium and barium all belong to group 2 hence they have similar chemical and physical properties.

17. 50% chances of round offspring
18. 25% chances two copies of dominant allele in the genotype of offspring
Explanation:
17. In this question it is stated that the Spongebob is heterozygous and has a square body which means the square body is dominant over the round that is present in sponge Susie that means she has two copies of the recessive allele.
S for square trait and s for a round trait then
S s
s Ss ss
s Ss ss
Thus, the correct answer is 50 percent as there are only two copies of ss.

Answer: The enthalpy change for formation of butane is -125 kJ/mol
Explanation:
The balanced chemical reaction is,
[tex]C_4H_{10}(g)+\frac{13}{2}O_2(g)\rightarrow 4CO_2(g)+5H_2O(l)[/tex]
The expression for enthalpy change is,
[tex]\Delta H=[n\times H_f{products}]-[n\times H_f{reactants}][/tex]
Putting the values we get :
[tex]\Delta H=[4\times H_f_{CO_2}+5\times H_f_{H_2O}]-[1\times H_f_{C_4H_{10}}+\frac{13}{2}\times H_f_{O_2}][/tex]
[tex]-2877=[(4\times -393)+(5\times -286)]-[1\times H_f_{C_4H_{10}}+\frac{13}{2}\times 0][/tex]
[tex]H_f_{C_4H_{10}=-125kJ/mol[/tex]
Thus enthalpy change for formation of butane is -125 kJ/mol
Explain why it is necessary to use a mixture, alumina and cryolite, rather than just
alumina
Explanation:
The mixture of cryolite and aluminium oxide has a lower melting point than pure aluminium oxide. This means a lower amount of energy is required to establish effective conditions for electrolysis and thus makes it more cost effective.
