Draw the structure of the diene that reacts with one equivalent of HBr to form the following two compounds as the only bromoalkene products

Answers

Answer 1

Diene is a type of organic compound that contains two double bonds between two carbon atoms.

What are Atoms?

Atoms are the smallest particle of any element that still maintains the properties of that element. Atoms are made up of a nucleus surrounded by one or more electrons. The nucleus is composed of protons and neutrons, and the electrons orbit around the nucleus. Atoms of different elements have different numbers of protons, neutrons, and electrons, which is what gives them their unique properties.

Diene is a conjugated molecule, meaning that its double bonds alternate with single bonds. Diene molecules are used in a variety of chemical reactions, including the formation of polymers and the synthesis of pharmaceuticals.

The planes of cleavage that the mineral have is 1 as the mineral name is Muscovite mica.

The crystal lattice structure of a mineral affects its propensity to split or break along flat planar faces, or cleavage. These 2D surfaces, also known as cleavage planes, are produced by the alignment of atoms in the crystal structure or lattice through relatively weak connections.

The mineral depicted in the image is called "Muscovite mica," and it has layers that seem like flat sheets. Muscovite mica is far more likely to break along the layers because it only has weakly bonded potassium ions. There is just one ideal cleavage plane as a result.

What will be the pH of solution after sodium acetate solution in the middle or the last column reacts with the specified concentration of HCl

Answers

The pH of the final solution will be less than 7, but closer to 7 if the initial concentration of sodium acetate is high and the concentration of HCl is low.

The pH of a solution after a reaction with a strong acid like HCl will depend on the concentration of the acid and the concentration of the acetate ions (CH3COO-) in the sodium acetate solution. Sodium acetate (CH3COONa) is a weak base, and when it reacts with HCl, it forms acetic acid (CH3COOH) and sodium chloride (NaCl). The equation for this reaction is: CH3COONa + HCl → CH3COOH + NaClThe pH of a solution is a measure of the concentration of hydronium ions (H3O+) in the solution, so the pH of the solution after the reaction will depend on the concentration of H3O+ ions and the concentration of acetate ions. If the reaction is done in aqueous solution, the acetic acid formed will dissociate to form H3O+ and acetate ions. The acetate ions will neutralize some of the H3O+ ions, thus decreasing the overall acidity of the solution. The pH of the final solution will be less than 7, but closer to 7 if the initial concentration of sodium acetate is high and the concentration of HCl is low. It's important to note that without knowing the initial concentration of sodium acetate and the volume of the solutions it is not possible to determine the final pH.

ΔΗ =-726 kj

How many kilojoules are released when 75 g of CH4O Reacts?

Answers

The amount of heat released when 75 g of CH4O reacts is -1705.64 kJ.

The equation given is the balanced equation for the combustion of methanol (CH4O) with oxygen to form carbon dioxide (CO2) and water (H20). The value of ΔΗ given (-726 kJ) is the enthalpy change for the reaction, which represents the amount of heat released or absorbed when the reaction occurs.

To calculate the amount of heat released when 75 g of CH4O reacts, we need to use the equation: q = n x ΔΗ where,

q is the heat releasedn is the number of moles of CH4O reacting ΔΗ is the enthalpy change for the reaction.

We know that the molar mass of CH4O is 32.04 g/mol, so we can convert 75 g to moles using the following formula: n = m/M where,

n is the number of molesm is the mass of CH4O M is the molar mass of CH4O.

So, n = 75 / 32.04 = 2.34 moles

Using this value of n in the equation above, we can calculate the heat released as q = 2.34 x -726 = -1705.64 kJ

Therefore, -1705.64 kJ of heat is released when 75 g of CH4O reacts.

O petrified wood and Tyrannosaurus

Answers

Lystrosaurus and Glossopteris are two pieces of fossil evidence support the idea of continental drift.

One of the geologist's first theories about how continents moved over time was continental drift.  The science of plate tectonics has been largely supplanted the hypothesis of the continental drift. Alfred Wegener has been most closely associated with the continental drift idea. Wegener released a paper in the early twentieth century describing his notion that continental landmasses were "drifting" across the Earth, occasionally ploughing through seas and into one other. He developed the term "continental drift" to describe this process.

Wegener found similarities in the coasts of eastern South America as western Africa and hypothesised that those countries had originally been part of a supercontinent called Pangaea, which had separated and travelled many kilometres away over geologic time. He also mentioned nearly comparable fossil creatures and rock layers that happened on vastly different continents. Colbert discovered Lystrosaurus fossils in the Transantarctic Mountains of Antarctica. Such fossils belonged to something like a species previously discovered in Africa, proving that the world's two most distant continents were formerly linked.

The moles of NaCl is given which is 0.23 and NaCl is dissolved in enough water which makes the solution of 395.6 mL.

The total number of moles of solute present in a given solution per litre is known as its molarity. In contrast to mass, which varies as the system's physical circumstances vary, the volume of a solution changes as a function of changes in the system's physical qualities, such as pressure and temperature. This has an impact on the molality of the solution. The symbol M, sometimes known as a molar, denotes molarity. A solution is considered to be one molar when one gram of the solute dissolves in one litre of the solution.

So, the molarity= [tex]\frac{totalnumber of moles}{total volume }[/tex]

molarity=[tex]\frac{0.23}{0.395}[/tex]

Mathematically,

V1/T1 = V2/T2

where,

V1 and T1 are the gas's starting volume and temperature.

V2 and T2 are the gas's ultimate volume and temperature.

C) 3.7 *10^–2 M
D) 1.3 * 10^1 M
E) 5.6 * 10^–3 M

Answers

The correct answer is D and B

Equilibrium constant K= 44.8 for H₂ + I₂ → 2HI Equimolar reactants, HI = 0.50M, H₂ = 5.6×10⁻³ M. The correct option is e.

given equilibrium constant (K) and the equilibrium concentration of the product HI = 0.50M

balanced equation for the reaction

H₂ + I₂ → 2HI

K =[tex]\frac{HI^{2} }{[H_{2][I_{2}] } }[/tex]

K=44.8 and [HI]=0.50M

[H₂] = [tex]\frac{[HI]^{2} }{K}[/tex]

[H₂] =[tex]\frac{(0.50M)^{2} }{44.8}[/tex]

[H₂] ≈0.0056M

equilibrium concentration of hydrogen is 0.0056M sa per the given reaction.

What does an element box contain?

Answers

The element box contains name and symbol of the element, number of protons and electrons, atomic mass, and electron configuration.

Each container represents an detail and incorporates its atomic size, symbol, common atomic mass, and (sometimes) name. The factors are organized in seven horizontal rows, referred to as intervals or series, and 18 vertical columns, referred to as groups. The container containing every detail's records is called the detail key. Each key incorporates an detail's name, precise symbol, atomic weight and atomic variety. Oxygen, for example, has an atomic variety of 8, an atomic weight of 15.996 and a completely unique symbol, O. The table is split into 4 more or less square regions referred to as blocks. The rows of the desk are referred to as intervals, and the columns are referred to as groups. Elements from the equal institution of the periodic table display comparable chemical characteristics.
