The correct answer is
1,4-dichloro-2-pentanone
The name of the given molecule will be "1,4-dichloro-2-pentanone".
What is molecule?A molecule represents the tiniest unit of a material that keeps its content and properties. It must be made up of two or more atoms that have been joined together by chemical bonds.
What is 1,4-dichloro-2-pentanone?This molecule will be made by carbon, oxygen , hydrogen and oxygen molecule.
It can be seen that given molecule has 5 carbon atom in which 1 and 4 position of carbon atom chlorine atom is present and at 2 carbon oxygen atom is presence. that's why the name of the given molecule will be "1,4-dichloro-2-pentanone".
In this molecule one ketone and two halogen (Cl) groups are present that's why it can be consider as keto halogen compound.
The molecular formula of this compound can be written as [tex]C_{5} H_{10} Cl_{2} O[/tex]. Presence of oxygen molecule indicate that keto group should be present in the given molecule . So the name of the compound should be 1,4-dichloro-2-pentanone

If 5.60 mol of a substance releases 14.9 kJ when it decomposes, what is ΔH for the process in terms of kJ/mol of reactant?
Answers
Answer:
The correct approach is "-2.67 kJ/mole". A further solution is described below.
Explanation:
The given values are:
No. of moles,
= 5.60 mol
Substance releases,
ΔH = 14.9 kJ
Now,
The ΔH in terms of kJ/mol will be:
= [tex]\frac{\Delta H}{5.60}[/tex]
On putting the given values of ΔH, we get
= [tex]\frac{-14.9}{5.60}[/tex]
= [tex]-2.67 \ kJ/mole[/tex]
A sample of nitrogen gas in a 750.0 mL sealed flask exerts a pressure of 206.58 kPa. Calculate the temperature of the gas if the flask contains 3.00 grams of gas.
Answers
Answer:
T= -99 °C.
Explanation:
Hello there!
In this case, according to the given description of the problem, it is possible for us to analyze this problem via the ideal gas equation:
[tex]PV=nRT[/tex]
However, we first calculate the moles in 3.00 grams of nitrogen gas (28.01 g/mol):
[tex]n=3.00g*\frac{1mol}{28.01g}=0.107mol[/tex]
Next, we solve for the temperature as shown below:
[tex]T=\frac{PV}{Rn}[/tex]
Next, we convert the given pressure and volume to atm and L to obtain:
[tex]T=\frac{(206.58atm/101.325)*750.0L/1000}{0.08206\frac{atm*L}{mol*K}*0.107mol}\\\\T=174.15K-273.15\\\\T=-99\°C[/tex]

What must happen to uranium before it can be used as a fuel source?
A. No changes are necessary.
B. Stable U-235 must be enriched with 3% radioactive U-238.
C. Stable U-238 must be enriched with 3% radioactive U-235.
D. Unstable U-235 must be enriched with 5% U-238 to stabilize it.
Answers
Answer:
D
Explanation:
Before it can be used in a reactor for electricity generation, however, it must undergo a series of processes to produce a useable fuel. For most of the world's reactors, the next step in making the fuel is to convert the uranium oxide into a gas, uranium hexafluoride (UF6), which enables it to be enriched.
Unstable U-235 must be enriched with 5% U-238 to stabilize it. Hence, option D is correct.

Covalent bonding occurs when... a electrons are shared between atoms b cations attract to anions c protons fuse in the nucleus d electrons are transferred between atoms
Answers
Answer: Covalent bonding occurs when electrons are shared between atoms. The correct option is A.
Explanation:
When atoms form a bond by sharing one or more pairs of electrons the bond is referred to as a COVALENT BOND. This is so because CV there is a natural drive for atoms to attain the electronic configuration of Group 0 which has a completely filled outermost shell of eight electrons. The covalent bond usually occurs among non- metals. Example of covalent bonding is seen in the formation of chlorine and carbondioxide molecules. Chloride atom which contains seven electrons in its outermost shell shares an electron with another chloride atom to attain a filled outermost shell leading to the formation of a chlorine molecule.
The characteristics of a covalent compound includes:
--> they contain only molecules. There are no ions, hence they do not conduct electricity.
--> they dissolve in organic solvents. They are insoluble in water.
--> they have low melting and boiling points.
which type of bonding involves sharing valence electrons, but the valence electrons aren't confined to a specific region between atoms and instead exist throughout the crystal structure of the material?
Answers
Answer:
metallic bonding
Explanation:
Metallic bonding is bonding where electrons exist as "sea of electrons" meaning they can go anywhere in the structure and are not localized in specific place like covalent bonds are sometimes.

If we were to add a piece of solid Cu to an aqueous solution (in water) of silver nitrate, the Silver would be replaced in a single replacement reaction forming aqueous copper (II) nitrate and solid silver. How much silver, in grams, is produced if 15.00 grams of Cu is added to the solution of silver nitrate
Answers
Answer:
50.9 g of Ag
Explanation:
Reaction is:
Cu (s) + 2AgNO₃(aq) → 2Ag (s) + Cu(NO₃)₂ (aq)
1 mol of Cu react to 2 moles of silver nitrate in order to produce 2 moles of solid silver and 1 mol of copper (II) nitrate.
We assume, the silver nitrate in excess.
We determine moles of copper → 15 g . 1mol / 63.55 g = 0.236 moles
Ratio is 1:2. 1 mol of copper produce 2 moles of silver
0.236 moles of Cu will produce (0.236 . 2) / 1 = 0.472 moles of Ag
We deterine mass of silver:
0.472 mol . 107.87 g /mol = 50.9 g

What is the molality of an acetic acid solution that contains 0.500 mol of HC2H3O2 (molar mass: 60g/mol) in 0.800 kg of water?
Answers
Answer: The molality of given acetic acid solution is 0.625 m.
Explanation:
Given: Moles of solute = 0.5 mol
Mass of solvent = 0.8 kg
Molality is the number of moles of solute present in a kg of solvent.
Therefore, molality of the given solution is calculated as follows.
[tex]Molality = \frac{moles}{mass of solvent}[/tex]
Substitute the values into above formula as follows.
[tex]Molality = \frac{moles}{mass of solvent}\\= \frac{0.5 mol}{0.8 kg}\\= 0.625 m[/tex]
Thus, we can conclude that the molality of given acetic acid solution is 0.625 m.
