Answer:
A.) trans-2,3-dichloro-5-methyl-2-hexene
Explanation:
The proposed question and structure has been attached to this answer.
The cis- and trans- isomers are used to denote the alignment of the functional groups to the carbon chain side. From the diagram, we see that:
the two chloro groups on the main compound are in opposite directions (-trans), and not the same sides (-cis)The bottom extended methyl group is on the 5th carbon as we count from left to rightthere's a total of 6 carbon atoms with 1 double bond on the second to third carbon.Hence the name trans-2,3-dichloro-5-methyl-2-hexene

Protons and neutrons have most of the mass but occupy very little of the volume of the atom.
Answers
Protons and neutrons have most of the mass but occupy very little of the volume of the atom.
The statement concerning the structure of the atom is correct is Protons and neutrons have most of the mass but occupy very little of the volume of the atom. Therefore, option D is correct.
What is an atom ?Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus. Only the most prevalent type of hydrogen is neutron-free. Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma.
But when it comes to the name atom, we must travel back to 400 B.C. ancient Greece. The Greek word atomos, which meaning "uncuttable," was proposed by Democritus, a renowned philosopher. In the end, all matter could be reduced to distinct, tiny particles, or atomos, he said.
The smallest unit of matter that may be divided without producing electrically charged particles is the atom.
Thus, option D is correct.

If 6.63 g of CuNO3 is dissolved in water to make a 0.140 M solution, what is the volume of the solution in milliliters?
Answers
Answer:
377mL is the volume of the solution
Explanation:
A 0.140M solution of CuNO₃ contains 0.140 moles of CuNO₃ per liter of solution. Thus, we need to convert first the mass of CuNO₃ to moles using its molar mass and, with the moles available, we can find the volume of the solution, thus:
Moles CuNO₃ -Molar mass: 125.55g/mol:
6.63g * (1mol / 125.55g) = 0.0528 moles of CuNO₃.
Volume of solution:
0.0528 moles of CuNO₃ * (1L / 0.140 moles CuNO₃) = 0.377L
0.377L * (1000mL / 1L) =

B) a method to dispose of the waste produced by fusion reactions
C) a way to contain fusion reactions
D) materials that will participate in fusion
Answers
Answer:
b is the correct answer....
To solve such this we must know the concept of fusion reactions. Therefore, the correct option is option B that is a method to dispose of the waste produced by fusion reactions.
What is chemical reaction?Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved.
Fusion processes, which convert protons into heavier elements, are the source of energy generation in stars. They are also a possible source of energy for contemporary industrial society. The transformation of hydrogen to helium is the primary source of energy in stars. There are no self-sustaining fusion reactors operating in the world because there is currently a lack of a method to dispose of the waste produced by fusion reactions.
Therefore, the correct option is option B.

Decide which element probably has a density most and least similar to the density of potassium. Comparing density:
lead rubidium thallium xenon
most similar to potassium
least similar to potassium
Answers
Answer:
most similar to potassium = rubidium
least similar to potassium = thallium
Explanation:
The density of an element is the number of particles per unit volume. To determine the element with the most probable density and the least density, we need to know their density values.
For potassium, density = 0.862 g/cm³
Density of lead = 11.35 g/cm³
Density of rubidium = 1.63 g/cm³
Density of thallium = 11.85 g/cm³
Density of xenon = 5.9 g.cm³
So from their density values, the density that has the most similar density to potassium is rubidium.
The element that is least similar to potassium is thallium.
One hour of bicycle racing can require 500-900 kcal of energy, depending on the speed of the race, the terrain, and the weight of the racer. Tour de France riders must consume abnormal amounts of food to supply this energy. Food in the form of protein or carbohydrates produces 17.0 kJ of energy per gram consumed. How many kilograms of protein or carbohydrate must be consumed to provide the energy for 175 minutes of racing that requires 650.0 kcal/hr?
Answers
Answer:
0.467 kilograms of protein or carbohydrates
Explanation:
First, there is a need to understand that 1 kJ = 0.239 kCal
Hence, 17 kJ = 17 x 0.239 = 4.063 kCal
The race requires 650.0 kCal/hr and has to last for 175 minutes.
175 minutes = 175/60 = 2.917 hrs
The total kCal requires for the race = 650 x 2.917 = 1,895.833 kCal
1 g of protein or carbohydrate food produces 17.0 kJ or 4.063 kCal of energy. Hence, the total g of protein or carbohydrate that will produce 1,895.833 kCal of energy would be;
1,895.833/4.063 = 466.609 g
1 g = 0.001 kg
466.609 g = 466.609 x 0.001 = 0.467 kg
Hence, 0.467 kilograms of proteins or carbohydrates must be consumed.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Answer: [tex]\Delta H^0[/tex] for the reaction [tex]Cl_2(g)+F_2(g)\rightarrow 2ClF(g)[/tex] is -108kJ
Explanation:
The balanced chemical reaction is,
The expression for enthalpy change is,
[tex]\Delta H=[n\times B.E_{reactants}]-[n\times B.E{products}][/tex]
where, n = number of moles
Now put all the given values in this expression, we get
[tex]\Delta H=[1\times B.E_{Cl_2}+1\times B.E_{F_2}]-[2\times B.E_{ClF}][/tex]
[tex]\Delta H=[(1\times 243)+(1\times 159)]-[2\times 255][/tex]
[tex]\Delta H=-108kJ[/tex]
Thus [tex]\Delta H^0[/tex] for the reaction [tex]Cl_2(g)+F_2(g)\rightarrow 2ClF(g)[/tex] is -108kJ
