1.The two green substances are not same thing because some of their properties are different and some of them are the same. If they were the same substance, all of their properties would have to be the same.

How could the explanation be improved?

Answers

Answer:

Even though the two substances possess many similarities, they have some unique properties. In turn, since they have the same properties, if they were the same substance, it would make matters worse, if the same chemical was in two different places, there would not be a difference between them since they are the same, just as it is with are two different chemicals would have differing properties since they are two properties would vary from one another since they are 2 totally different things!

What are some advantages to the use of hydrokinetic energy? What might be some disadvantages?.

Answers

Hydro-kinetic energy has advantages of being a clean, domestic, and renewable source with effective production. The disadvantages have been affected marine environment, along with water quality, and electricity on drought.

Hydro kinetic energy has been the energy produced by the movement of water bodies in the form of tides, waves, and oceanic current. The hydro-kinetic energy has been composed with high energy entrapped in the water bodies.

Some of the advantages of hydro-kinetic energy has been:

It has been a clean energy source and has been  pollution free.It has been used as domestic source of energy.It has been a renewable source of energy.It has been produced by the tidal waves, thus can be produced effective and in need.

Some of the disadvantages of hydro-kinetic energy has been:

Application of water bodies affects the marine environment.It has been producing low BOD and thereby affects the water quality.Conditions such as drought result in the affected electricity production.

Answer:

Some advantages to using hydrokinetic energy are that it can be used without mining materials, it is not associated with waste production, and that it does not contribute to air pollution. The main disadvantage to using hydrokinetic energy is the fact that it uses waves and tides as an energy source. This technology could not be used in all locations.

28) what is the number of oxygen atoms in the formula unit of Ca3(PO4)2?​

Answers

Answer:

4.816x10²⁴atoms

Explanation:

the number of moles of oxygen is 8

let x be number of oxygen atoms

recall that 1 mole=6.02x10^23 atoms

therefore, 8 moles =x

cross multiply

8 x 6.02 x 10^23 = x

x = 4.816 x 10²⁴atoms

The mass of oxygen required for complete utilization of 4 mol of Mg has been 64 g. Thus, option B is correct.

The balanced equation for the reaction has been:

[tex]\rm 2\;Mg\;+\;O_2\;\rightarrow\;2\;MgO[/tex]

From the balanced chemical equation, for complete utilization of 2 moles of Mg, 1 moles of oxygen has been used.

The given moles of Mg has been 4 mol. The moles of oxygen required can be given as:

[tex]\rm 2\;mol\;Mg=1\;mol\;O_2\\4\;mol\;Mg=2\;mol\;O_2[/tex]

Thus, the moles of oxygen required has been 2 mol for complete utilization of 4 mol Mg.

The mass from moles can be calculated as:

[tex]\rm Mass=Moles\;\times\;molecular\;mass[/tex]

The molecular mass of oxygen has been 32 g/mol.

The mass of oxygen has been:

[tex]\rm Mass=2\;\times\;32\;g\\Mass=64\;g[/tex]

The mass of oxygen required for complete utilization of 4 mol of Mg has been 64 g. Thus, option B is correct.

Answers

The new volume of the gas at 20 °C is 205 mL

From the question given above, the following data were obtained:

Initial volume (V₁) = 250 mL Initial pressure (P₁) = 10 atmInitial temperature (T₁) = 25 °C = 25 + 273 = 298 KNew pressure (P₂) = 12 atmNew temperature (T₂) = 20 °C = 20 + 273 = 293 KNew volume (V₂) =?

With the application of the combine gas equation, we can obtain the new volume of the gas as illustrated below:

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} \\ \\ \frac{10 \times 250}{298} = \frac{12 \times V_2}{293} \\ \\ \frac{2500}{298} = \frac{12 \times V_2}{293} \\ \\ cross \: multiply \\ \\ 298 \times 12 \times V_2 = 2500 \times 293 \\ \\ divide \: both \: side \: by \: 298 \times 12 \\ \\ V_2 = \frac{2500 \times 293}{298 \times 12} \\ \\ V_2 = 205 \: mL \\ [/tex]

Therefore, the new volume of the gas is 205 mL

The new volume of the gas is calculated by applying general gas equation as follows;

[tex]\frac{V_1 P_1}{T_1} = \frac{V_2P_2}{T_2} \\\\V_2 = \frac{V_1P_1 T_2}{T_1P_2} \\\\V_2 = \frac{(250\ mL) \times 10 \times 293}{298 \times 12} \\\\V_2 = 204.84 \ mL\\\\v_2 = 205 \ mL[/tex]

Answer: It is conserved.

Explanation: When the box is pushed across the floor, then floor and box becomes warm which resembles the condition of conservation of energy.

The given problem can be resolved by the concept of energy conservation. The statement of energy conservation says that, "Energy is neither be created nor be destroyed, but it is converted from one form to another.

In the given problem, the person pushes the box across the floor, such that the mechanical energy from the moving arms of person is transferred to the box, and the box and floor becomes warm.

During this process, the energy from the person moving arm is transferred to the box in the form of kinetic energy. And thus kinetic energy is then being transferred to thermal energy or heat energy, due to which the box and floor becomes warm.

Thus, we can conclude that the given case reflects the process of transformation of energy from one state to another, which highlights that during the process, energy is conserved.

Answers

The compound with the presence of higher inter-molecular forces has been Acetic acid. Thus, option A is correct.

The boiling point has been the temperature, at which the liquid has been started to convert to steam. The boiling has been mediated with the application of the energy to the substance for the breaking of the inter-molecular forces.

The higher the inter-molecular forces in the compound, the higher will be the boiling point of the compound. The higher concentration has also resulted in a higher boiling point.

In the following compounds, acetic acid has the highest boiling point of 118 degrees Celsius. Thus, it has been constituted of the higher inter-molecular forces. Hence, option A is correct.

In which of the following reactions is chlorine (Cl) oxidized? Br2 2Cl⒠→ Cl2 2Br⒠Cl2 2e⒠→ 2Cl⒠2ClO3⒠12H → Cl2 6H2O 2Na Cl2 → 2NaCl.

Answers

The reaction in which Cl has been oxidized is [tex]\rm Br_2\;+\;2\;Cl^-\;\rightarrow\;Cl_2\;+\;2\;Br^-[/tex]. Thus, option A is correct.

In a reaction, the oxidation has been defined as the loss of electrons by the atom, while reduction has been depicted as the gain of electrons.

The loss of electrons imparts a positive charge to the atom, while the gain of electrons imparts a negative charge to the atom.

In the following reactions, the Cl has been given as:

[tex]\rm Br_2\;+\;2\;Cl^-\;\rightarrow\;Cl_2\;+\;2\;Br^-[/tex]

The chlorine has loses the electron and is converted to diatomic molecule. Thus, the Cl has been oxidized. The oxidation state of Cl has also been increased from -1 to 0.

[tex]\rm Cl_2\;+\;2\;e^-\;\rightarrow\;2\;Cl^-[/tex]

The chlorine gains 2 electrons in the reaction and has been reduced.

[tex]\rm 2\;ClO_3^-\;+\;12\;H^+\;\rightarrow\;Cl_2\;+6\;H_2O[/tex]

There has been no change in the oxidation state of chlorine. Thus, Cl has not been oxidized.

[tex]\rm 2\;Na\;+\;Cl_2\;\rightarrow\;2\;NaCl[/tex]

The chlorine gains electron and has been converted to the Cl ion. With the gain of electrons, Cl has been reduced.

The reaction in which Cl has been oxidized is [tex]\rm Br_2\;+\;2\;Cl^-\;\rightarrow\;Cl_2\;+\;2\;Br^-[/tex]. Thus, option A is correct.
