Predict the initial and isolated products for the reaction. The starting material is a 6 carbon chain where there is a triple bond between carbons 3 and 4. This reacts with H 2 O, H 2 S O 4, and catalytic H g 2 plus to form an initial product. The initial product converts to the more stable isolated product but is in equilibrium. Hint: the products are isomers and in equilibrium with each other.
Answers
Answer:
See explanation and image attached
Explanation:
This reaction is known as mercuric ion catalyzed hydration of alkynes.
The first step in the reaction is attack of the mercuric ion on the carbon-carbon triple bond, a bridged intermediate is formed. This bridged intermediate is attacked by water molecule to give an organomercury enol. This undergoes keto-enol tautomerism, proton transfer to the keto group yields an oxonium ion, loss of the mercuric ion now gives equilibrium keto and enol forms of the compound. The keto form is favoured over the enol form.

The chemical symbol of given electronic configuration is Ne.
Explanation:
First of all we will calculate the total number of electron from this electronic configuration:
1s² 2s² 2p⁶ = 2+2+6 = 10
we know that the number of electron of an atom shows its atomic number. The total number of electron in given electronic configuration are 10.
Now from periodic table we got to know that neon has atomic number of 10.
Thus the given electronic configuration is of neon atom.
Neon is belongs to noble gas family.
All noble gases have complete octet.
These are inert gases.

MnO4- + 5 VO +2 + 11 H2O = 5 V(OH)4+ + Mn+2 + 2 H+
Explanation:
The balanced redox reaction is MnO⁴⁻ + 5 VO⁺² + 11 H₂O = 5 V(OH)⁴⁺ + Mn+2 + 2 H⁺.
What are redox reactions?Redox reactions are those reactions in which there is the transfer of electrons between different elements. These reactions are of two types, oxidation and reduction reactions. Examples are combustion, displacements, corrosion, and rusting reactions.
An example of a chemical reaction in which one or more electrons are lost is an oxidation reaction.
A reduction reaction is one in which one or more electrons are acquired during a certain kind of chemical reaction.
The formation of hydrogen fluoride is a redox reaction.
H₂ + F₂ = 2HF
H₂ = 2H + 2e⁻
F₂ + e⁻ = 2F⁻
Thus, the reaction is MnO⁴⁻ + 5 VO⁺² + 11 H₂O = 5 V(OH)⁴⁺ + Mn+2 + 2 H⁺.

A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 21.0cm wide and 25.2cm high. The maximum safe pressure inside the vessel has been measured to be 4.00MPa. For a certain reaction the vessel may contain up to 0.474kg of boron trifluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Be sure your answer has the correct number of significant digits.
Answers
Answer:
Explanation:
Volume of cylinder = πr²h where r is radius of cylinder, h is height of cylinder
r = d/2 = 21/2 = 10.5 cm; h = 25.2 cm
volume of cylinder = (22 * 10.5 cm * 10.5 cm * 25.2 cm) / 7
volume = 8731.8 cm³ = 8.7318 L
Using the ideal gas equation, PV = nRT
P = 4.00 MPa = 4.0 * 10³ kPa, V = 8.7318 L, R = 8.314 L.kPa/mol.K,
n = mass / molar mass
where mass = 0.474 kg or 474 g, molar mass of BF₃= 68 g/mol
n = 474 g / 68 g/mol = 6.9706 moles
making T subject of formula in the ideal gas equation;
T = PV/nR
T = (4.0 * 10³ kPa * 8.7318 L)/(6.9706 mol * 8.314 L.kPa/mol.K)
T = 602.675 K
T in °C = K - 273.15
T = 602.675 -273.15 = 329.5 °C
T = 330 °C

How many grams of C12 can be prepared from the reaction of 16.0 g of MnO2 and 30.0 g of HCl according to the following chemical equation? Mn02 + 4HCI → MnCl2 + Cl2 + 2H2O
Answers
Answer:
Mass of Cl₂ produced 12.78 g
Explanation:
Given data:
Mass of MnO₂ = 16 g
Mass of HCl = 30.0 g
Mass of Cl₂ produced = ?
Solution:
Chemical equation:
MnO₂ + 4HCl → MnCl₂ + Cl₂ + 2H₂O
Number of moles of MnO₂:
Number of moles = mass / molar mass
Number of moles = 16 g/ 87 g/mol
Number of moles = 0.18 mol
Number of moles of HCl:
Number of moles = mass / molar mass
Number of moles = 30 g/ 36.46 g/mol
Number of moles = 0.82 mol
Now we will compare the moles of Cl₂ with MnO₂ and HCl.
MnO₂ : Cl₂
1 : 1
0.18 : 0.18
HCl : Cl₂
4 : 1
0.82 : 1/4×0.82 = 0.205 mol
The number of moles of Cl₂ formed by HCl are less it will limiting reactant.
Mass of Cl₂ formed:
Mass = number of moles × molar mass
Mass = 0.18 mol × 71 g/mol
Mass = 12.78 g

HELP NOW!!!!!! When you put water into a hot metal pan of equal mass, why does the pan cool down more than the water heats up?
Answers
Answer:
Because the specific heat of the metal is less than the specific heat of water.
Explanation:
Hello, happy to help you today!
In this case, we need to analyze a property called "specific heat" which accounts for how much energy is required to increase or decrease the temperature of 1 g of the substance by 1 °C.
In this case, since the specific heat of water is about 4.184 J/g°C and the specific heat of metals in general is greater than zero, of course, but less than one, we can infer that for the same amount of energy, when they are in contact, more grams of metal will be cooled down to those of water heated up, because the specific heat of the metal is less than the specific heat of water.

How much energy (in kcal) is involved when 5.2 g of water at 0.0oC is converted to ice? Enter only the numeric value for your answer (no units).
Answers
Answer:
[tex]Q=0.41kcal[/tex]
Explanation:
Hello.
In this case, since the energy involved during this process is associated to the freezing enthalpy of water at the freezing point of water (0.0 °C) and is computed via:
[tex]Q=m\Delta _{freezing}H[/tex]
It is known that the freezing enthalpy of water is -333.3 J/g, therefore, the involved heat is:
[tex]Q=5.2g*-333.33\frac{J}{g}\\ \\Q=-1733.33J[/tex]
Clearly, it is negative since freezing requires the removal of energy, which means it is negative based on the first law of thermodynamics. Finally, the energy in kcal turns out:
[tex]Q=1733.33J*\frac{1kcal}{4184kJ}\\ \\Q=0.41kcal[/tex]

Ideal gas law is valid only for ideal gas not for vanderwaal gas. Combined Boyle's gas law is used here. Therefore the new pressure inside the container will be 0.833 atm.
What is ideal gas equation?Ideal gas equation is the mathematical expression that relates pressure volume and temperature.
Mathematically the relation between Pressure, volume and temperature can be given as
PV=nRT
where,
P = pressure of ideal gas
V= volume of ideal gas
n =number of moles of ideal gas
T =temperature of ideal gas
R = Gas constant = 0.0821 L.atm/K.mol
According to Boyle's gas law
P₁V₁ = P₂V₂
Substituting all the given values in the above equation, we get
(1 atm) (1 L) =(P2) ( 1.60L )
P2 = 0.833 atm
Therefore the new pressure inside the container will be 0.833 atm.
