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

A sample of ethanol (C2H6O) has a mass of 0. 2301 g. Complete combustion of this sample causes the temperature of a bomb calorimeter to increase by 1. 33°C. The calorimeter has a mass of 2. 000 kg and a specific heat of 2. 45 J/g•°C. What is the heat of combustion for this sample? kJ.

Answers

The heat of combustion of the sample is calculated to be  -1300 kJmol-1.

We know that energy is neither created nor destroyed but is converted from one form to another. The heat lost by the ethanol when it is burnt is equal to the heat gained by the calorimeter.

Heat gained by calorimeter =  2.×10^3 g ×  2. 45 Jg-1°C-1 × 1. 33°C

= 6.5 kJ

Number of moles of ethanol =  0. 2301 g/46 g/mol = 0.005 moles

Heat of combustion of the sample = -( 6.5/0.005 moles) = -1300 kJmol-1

The percent of attacks on the dark-colored mouse models is how many times greater than the percent of attacks on light-colored models

Answers

The number of times the percentage of attacks on the dark-colored mouse is greater than the percentage of attacks on light-colored mouse is four (4) times.

Let the percent of attacks on the dark-colored mouse be D.Let the percent of attacks on light-colored mouse be L.

Given the following data:

Light-colored mouse models = 20 percentDark-colored mouse models = 80 percent

To determine the number of times the percentage of attacks on the dark-colored mouse is greater than the percentage of attacks on light-colored mouse.

Therefore, we would simply divide the percentage for the dark-colored mouse by the percentage for the light-colored mouse as follows:

[tex]Number \;of\;times = \frac{D}{L}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Number \;of\;times = \frac{80}{20}[/tex]

Number of times = 4 times.

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.

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.
