Answer 1

Answer:

A

Explanation:

Alkanes undergo substitution reaction with halogen molecules in the presence of light. This reaction occurs by free radical mechanism and the initiation step is the formation of the halogen radical.

The propagation steps involves the abstraction of a hydrogen from the alkane by the halogen radicals.

The termination steps involves the coupling of alky radicals.

Thus for the reaction of ethane and chlorine;

C2H6 + Cl2 -------> C2H5Cl + HCl

QUESTION: IDENTIFY THE PROCESS

Answers

Answer: Electrolysis is passing an electric current through a liquid containing ions so that decomposition reaction takes place.

Electrolysis is passing an electric current through a liquid containing ions so that decomposition reaction takes place.When an electric current is passed through acidified water, it decomposes to give hydrogen and oxygen gas. The hydrogen gas is obtained at the cathode and the oxygen gas is obtained at the anode.

Answers

Answer:

La reacción de etano, CH₃CH₃ y cloro, Cl₂ en presencia de luz solar se conoce como reacción de halogenación.

Los radicales de cloro se forman cuando el cloro se expone a la luz solar a continuación;

Cl₂ → 2Cl *

Se forma un radical etano cuando el etano, C₂H₆ reacciona con un radical libre de cloro, Cl *, como sigue;

C₂H₆ + Cl → C₂H₅ * + HCl

Se forma un producto halogenado cuando un radical libre de etano reacciona con una molécula de cloro como sigue;

C₂H₅ * + Cl₂ → C₂H₅Cl + Cl *

Un producto halogenado puede reaccionar además con un radical libre para producir como sigue;

O B. They decay at a predictable rate.
C. Their decay products are easy to detect.
O D. They all have extremely long half-lives.

Answers

Answer:A

Explanation:

Option D. They all have extremely long half-lives makes radioisotopes useful for dating objects.

What are radioisotopes?

Radioisotopes exist as radioactive isotopes of an element. They can also be described as atoms that include an unstable combination of neutrons and protons, or surplus energy in their nucleus.

A radionuclide exists as a nuclide that contains excess nuclear energy, causing it unstable. This excess energy can be utilized in one of three methods: emitted from the nucleus as gamma radiation; assigned to one of its electrons to terminate it as a conversion electron; or utilized to create and emit a unique particle from the nucleus.

Radioactive isotopes of radium, thorium, and uranium, for example, exist found naturally in rocks and soil. Uranium and thorium also happen in trace amounts in water. Radon, induced by the radioactive decay of radium, stands present in the air.

Hence, Option D. They all have extremely long half-lives makes radioisotopes useful for dating objects.

3.60x10⁵cal

Explanation:

Using the HFusion we can find the heat needed to convert the ice to liquid water.

With specific heat capacity we can find the heat needed to increase the temperature of water from 0 to 100°C.

With HVap we can find the heat to convert the liquid water into steam.

The equations are:

HFusion*mass + Spec.Heat*mass*ΔT + HVap*mass

Computing the values:

80cal/g*50.0g + 1.00cal/g°C*50.0g*(100°C-0°C) + 540cal/g*50g

Answers

Answer: The correct net ionic equation for the reaction is [tex]2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)[/tex]

Explanation:

Net ionic equation is defined as the equations in which spectator ions are not included.

Spectator ions are the ones that are present equally on the reactant and product sides. They do not participate in the reaction.  

The balanced molecular equation is:

[tex]Ca(OH)_2(aq)+H_2SO_4(aq)\rightarrow CaSO_4(aq)+2H_2O(l)[/tex]

The complete ionic equation follows:

[tex]Ca^{2+}(aq)+2OH^-(aq)+2H^+(aq)+SO_4^{2-}(aq)\rightarrow 2Ca^{2+}(aq)+SO_4^{2-}(aq)+H_2O(l)[/tex]

As calcium and sulfate ions are present on both sides of the reaction. Thus, they are considered spectator ions.

The net ionic equation follows:

[tex]2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)[/tex]

Hence, the correct net ionic equation for the reaction is [tex]2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)[/tex]

Barbara is conducting an experiment to observe heat flow. She places one piece of metal in a freezer at -18 degrees Celsius (°C) and a second piece of metal in an oven at 200 °C. After 2 hours, she takes the metal pieces out of the freezer and oven and places them both in the same beaker of boiling water for two minutes. Which of the following best describes how some of the heat will initially move in this system?


Heat will flow from the frozen metal into the hot metal.


Heat will flow from the boiling water into the hot metal.


Heat will flow from the boiling water into the frozen metal.


Heat will flow from the frozen metal into the boiling water.

Answers

Answer: The correct answer is heat will flow from the boiling water into the frozen metal.

Explanation:

According to the law of conservation of energy, energy cannot be destroyed nor created but it can be transformed from 1 form to another form.

There are 3 processes of heat transfer:

Conduction: This type of heat transfer occurs when there is direct contact between the two objects.Convection: This type of heat transfer occurs when there is a movement of fluid (liquid or gas) due to the movement of hot layers to the top and cold layers to the bottom which leads to convection currents.  Radiation: This type of heat transfer occurs when there is a direct transfer of energy through space.

The heat moves from a hot surface to a cold surface to maintain equilibrium.

We are given:

A metal is placed in a freezer (cold object) and another metal is placed in an oven (hot object) and then both the metals are placed in boiling water.

Initially, the heat will flow from the boiling water (hot object) into the frozen metal (cold object) to maintain equilibrium

Hence, the correct answer is heat will flow from the boiling water into the frozen metal.

Michael is studying the factors that affect corrosion of metals. He wants to test the effect that different concentrations of an acid will have on the corrosion of a metal. As he sets up and completes his experiment, which of the following experimental designs would be most likely to help him answer his question? A. Allow several metal samples to soak in different amounts of acid of a single concentration and then measure the amount of corrosion on each. B. Prepare solutions of different acid concentrations, measure 50 milliliters of each into different beakers, and place metal samples of different types but of the same mass into the beakers. C. After allowing several small metal sheets to be exposed to different acid concentrations, measure the surface area of each that is corroded. D. After allowing a small metal sheet to be exposed to one acid concentration, place it in different acid concentrations, then measure the surface area that is corroded.

Answers

Answer:

B. Prepare solutions of different acid concentrations, measure 50 milliliters of each into different beakers, and place metal samples of different types but of the same mass into the beakers.

Explanation:

Since Michael is studying the factors that affect corrosion of metals, and wants to test the effect that different concentrations of an acid will have on the corrosion of a metal, using different acid concentrations of the same volume on different metal samples of the same size would give a much better than all the other options because, a standard volume of acid is used and also a standard mass of metal is used. So, the effect can be measured quantitatively since we have the same quantity of sample.

So, option B is the answer

Which substance would you expect to dissolve most rapidly in 100 mL water?

A
0.4 g granulated sugar

B
0.2 g powdered sugar

C
0.4 g powdered sugar

D
0.2 g sugar cube

Answers

Answer:

b because it is just 0.2 g and powdered sugar has more contact surface than granulated sugar or sugar cube

The solubility can be given as the amount of solute that can be dissolved in the 100 ml of the solution. The most rapidly dissolved sugar in water is 0.2 gram powdered sugar.

What is a contact surface?

The contact surface can be given as the area of the compound that is in direct contact with the solution.

The solubility of the compound is found more in the solute with increased surface area.

The surface area of powdered sugar will be maximum, as more granules of the sugar will be in contact with the water than the cube or the granulated sugar.

Thus, the most rapid dissolution in water is found with 0.2 grams of powdered sugar. Thus, option B is correct.

initial temperature, T = 5 C

final temperature, T' = 75 C

specific heat, c = 4.18 J/g C

The amount of heat required is
