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.

an unknown gas diffuses 1.25 times faster than CO2 gas. What is the molar mass of the unknown gas?​

Answers

Answer:

28.16 g/mol

Explanation:

From Graham's law;

Let the rate of diffusion of gas X be 1.25

Let the rate of diffusion of CO2 be 1

Molecular mass of gas X= M

Molecular mass of CO2 = 44g/mol

1.25/1=√44/M

(1.25/1)^2 = 44/M

1.5625 = 44/M

M= 44/1.5625

M= 28.16 g/mol

What is a balanced nuclear equation for the alpha decay of Strontium-90?

Answers

Answer: The balanced nuclear equation for the alpha decay of Sr-90 is [tex]_{38}^{90}\textrm{Sr}\rightarrow _{36}^{86}\textrm{Kr}+_2^4\alpha[/tex]

Explanation:

A nuclear reaction is defined as the reaction in which the changes in the nucleus of an atom take place and usually form a different element. The types of decay processes are:

Alpha decayBeta-decayGamma decay

Alpha decay is the process in which a heavy nucleus decays into a light nucleus with the release of an alpha particle. This alpha particle carries a charge of +2 units and has a mass of 4 units. It is also known as the helium nucleus. The general equation for this decay process is:

[tex]X_Z^A\rightarrow Y_{Z-2}^{A-4}+\alpha _2^4[/tex]

The nuclear equation for the alpha decay of strontium-90 isotope follows:

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]

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.

Answers

Answer: The correct options are A, C and D.

Explanation:

Enthalpy of formation is defined as the change in the enthalpy when 1 mole of a chemical substance is formed from its pure element at standard conditions. It is represented by the symbol [tex]\Delta H_{f}[/tex]

Enthalpy of formation for elemental atoms is always equal to 0.

We know:

Bromine (Br) exists in a liquid state.

Helium (He) exists in a gaseous state.

Mercury (Hg) exists in a liquid state.

Chlorine (Cl) exists in a gaseous state.

Nitrogen (N) exists in a gaseous state.

For the given options:

The [tex]\Delta H_{f}[/tex] for [tex]Br_2(l), Hg(l)\text{ and }Cl_2(g)[/tex] will be equal to 0 because they are formed by the natural states of their elemental atoms.

Hence, the correct options are A, C and D.

A substance in its standard state has an enthalpy of formation of 0 kJ/mol.

The enthalpy of formation of a substance in its standard state is 0 kJ/mol.

The standard state of a substance refers to its state at 1 atm and at a temperature of 298 K. Bearing this in mind, we can now identify the true and false statements.

So,

ΔHf for Br2(I) is 0 kJ/mol - True

ΔHf for He(I) is 0 kJ/mol - False

ΔHf for Hg(I) is 0 kJ/mol - True

ΔHf for Cl2(g) is 0 kJ/mol - True

ΔHf for  N2(I) is 0 kJ/mol - False
