Answer:

German chemist G.E. Stahl

Explanation:

this theory was first articulated in 1697

G. E. Stahl in 1697 is the scientist who is  credited with early, quantitative data on redox reactions.

The Redox reactions comprise of two parts a reduced part and an oxidized part, which occur simultaneously . The part which is reduced gain electrons and hence there is a increase in oxidation state of the species.

While, the part which is oxidized looses electrons and hence there is a decrease in oxidation state of the species.During redox reactions, there is no net change in the number of electrons . Electrons which are given off in oxidation are used up in reduction.

The ion or molecule which accepts electrons is called as oxidizing agent while the ion or molecule which donates electrons is called as a reducing agent.

There are 75 grams in 2.5 moles of dicarbon hexahydride (C₂H₆).

The given parameters;

The molecular mass of dicarbon hexahydride is calculated as follows;

Mw = C₂H₆ = (2 x 12) + (6 x 1)

Mw =30 g/mol

The mass of the dicarbon hexahydride in the given number of moles is calculated as follows;

mass = n x Mw

mass = 2.5 x 30

mass = 75 g

Thus, we can conclude that there are 75 grams in 2.5 moles of dicarbon hexahydride (C₂H₆).

The Dehydrohaogenation of 1-bromo propane with alcoholic KOH gives propene which on again hydrohalogenation with HBr gives 2-bromo propane due to Markonikove's rule for addition.

Explanation:

The cations and anions can be identified using cataloged reactions schemes. For instance, the copper II ion can be identified by reaction with sodium hydroxide.

The sodium cation is easily identified by flame test. sodium imparts a yellow color to a flame. The chloride ion is identified by the use of a mixture of HNO3/AgNO3 solution. The color of the precipitate shows which halide ion is present. A white precipitate indicates the presence of the chloride ion.

The potassium cation is also identified by flame test. The ion imparts a lilac color to flame. Addition of acidified FeSO4 solution is used to confirm the presence of the nitrate ion. Formation of a brown ring is a positive test for the nitrate ion.

For CuSO4, the presence of copper II ion can be confirmed using dilute NaOH. If a light blue precipitate is formed which dissolves in excess NaOH then the copper II ion is confirmed. The presence of the sulfate ion is confirmed using a solution of barium nitrate and dilute nitric acid. Formation of a white precipitate is a positive test for the sulfate ion.

Standardization is the process of titrating a solution that is prepared from: a carefully measured solid mass to accurately find the concentration of titrant.

Titration is also known as volumetric analysis (titrimetry) and it can be defined as a chemical process in which a solution of known concentration (titrant) is carefully and slowly added to another solution of unknown concentration, so as to determine the concentration or quantity of the analyte.

Similarly, a process referred to as standardization is used to titrate a solution that is prepared from a carefully measured solid mass to accurately find the concentration of titrant.

Answer:

262.5 Joules

Explanation:

You find the kinetic energy of multiplying half of the mass by the velocity. In this word problem it tells you the mass so you divide it by 2. That answer is 2.625, you then multiply that by the velocity, in this instance it's 1.0 x 10^2 mi/h.

The unit in kinetic energy is Joules. This is actually a really important part in chemistry and physics.

The kinetic energy of a baseball (mass = 5.25 oz) with a velocity of 1.0×10² mi/h is 147.88 joules.

Kinetic energy of any object will be calculated by using the below equation:

K.E. = 1/2(mv)², where

m = mass of object in kg = 5.25 oz = 0.148 kg

v = velocity in m/sec = 1.0×10² mi/h = 160934 m/h = 44.704 m/s

On putting values on the above equation, we get

K.E. =1/2(0.148)(44.704)²

K.E. = 147.88 joules

Hence required kinetic enrgy is 147.88 joules.

The layer of Earth which provide transfer from the white core to the lithosphere that fuels convection is the mantle.

A mantle can be described as a layer inside a planetary body bounded above a crust and below a core. Mantles are composed of rock or ice and are usually the largest massive layer of the planetary body.

The mantle layer of the earth is a layer of silicate rock between the crust and the outer core. The mass of the mantle of 4.01 × 10²⁴ kg which is 67% of the mass of the Earth. It's a thickness of 2,900 kilometers making up about 84% of Earth's volume.

The mantle layer is predominantly solid, but it behaves as a viscous fluid. At mid-ocean ridges, partial melting of the mantle produces oceanic crust, and at subduction zones, partial melting of the mantle produces continental crust.

The temperatures range of the mantle from 200 °C at the upper boundary with the crust to  4,000 °C  at the core-mantle boundary. The convection of the mantle is a chaotic process,  the mantle transfers heat that fuels convection.

SN2 reaction proceeds with inversion of configuration at the reacting carbon atom. The product has a different configuration at this carbon atom from the product.

SN2 reaction is a short form for substitution nucleophilic bimolecular reaction. It is a synchronous reaction in which the leaving group departs at the same time as the nucleophile attacks in a single transition state.

Recall that SN2 reaction proceeds with inversion of configuration hence the product has a different configuration at the reacting carbon atom from the product. The inorganic product in this reaction is HI. The organic product is shown in the image attached to this answer.
