Explanation

Answer:

The traditional electrolyte for aluminium electrolysis is based on molten cryolite (Na3AlF6), acting as solvent for the raw material, alumina (Al2O3).Metals are found in ores combined with other elements. Electrolysis can be used to extract a more reactive metal from the ore.

Aluminum can and is used as both anodes and cathodes in electrochemical cells, but there are some peculiarities to using it as an anode in aqueous solutions. As you note, aluminum forms a passivating oxide layer quite readily, even by exposure to atmosphere. In an aqueous solution, if the potential is high enough, OH− and O2− are generated at the anode, which can then react with the aluminum to produce aluminum oxide. Al^3+ can also be generated directly. The electric field will draw the anions through the growing aluminum oxide layer towards the aluminum surface and the Al^3+ towards the solution, making the oxide layer grow both away from the electrode surface and into the surface of the electrode. In this way, coatings thicker than the normal passivation in air can be produced. However, aluminum oxide is a good electrical insulator, thus if a dense non-porous layer is grown, it will become impossible to pass current through it and growth will stop, leaving a relatively thin oxide layer (this is how the dielectric layers in electrolytic capacitors are made). This is the normal behaviour in aqueous solutions at near-neutral pH (5–7).

However, if a thick aluminum oxide layer is desired (e.g. to produce coatings on aluminum parts for dying or durability), maintaining porosity is necessary to avoid completely blocking access to the surface. One technique that is commonly used is using a low pH solution, which tends to redissolve some of the oxide and neutralize some of the formed OH−, leaving pores in the oxide layer through which the ions can travel and continue to react. These pores also give a good structure to retain dyes or lubricants, but generally need to be sealed after to protect against corrosion.

The answer would be C8H18, or octane. Column chromatography is a separation technique that works off of polarity. The stationary phase, in column chromatography, are non-modified silica gels. Silica gels are normally polar. This means the solvent that will elute first are non-polar molecules...then polar molecules. The polar silica gels have a stronger interaction with polar molecules like CH3OH, and therefore will lag the solvent. Additionally, as you decrease the carbons, in hydrocarbons, the molecule becomes more polar. This is not C6H6 isn't the answer and octane is.

C8H18 will travel the farthest in column chromatography.

There are different forms of chromatography. there is the column chromatography, Gas chromatography etc.

Alkanes are known to be least polar and as such would travel farthest into the mobile phase of the four functional groups. C8H18 belongs to the alkanes family.

Answer:

8% thymine

Explanation:

The percent of thymine in the given sample of the DNA will be equal to 8 %.

DNA, according to Chargaff, is composed of nucleotide subunits. These nucleotides are linked through two or more hydrogen-bonded to one another to form the double-stranded molecule of DNA.

The nucleotides found in the DNA molecule are Adenine, Thymine, Cytosine, and Guanine. Guanine (G) pairs with Cytosine (C) while  Adenine (A) pairs with Thymine (T).

According to Chargaff's rule, the amount of Adenine is equal to that of Thymine in a DNA molecule and the same applies to Guanine and Cytosine. We can consider that the total amount of nucleotides equals 1 or 100%.

[tex]A + T + G + C = 100\%[/tex]

If Cytosine is 42 % of the DNA sample, this means that guanine will also be  42%.

G + C = 42 + 42  = 84%

A + T = 100% - 84 % = 16%

This means that Adenine and Thymine amount to 16 %. The amount of each nucleotide will be 16% ÷ 2 = 12% i.e. A = T = 8 %

Therefore, the percent of thymine in the given sample of the DNA will be 8 %.

The British Petroleum (bp's) effort to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of regulatory policy change.

The deepwater horizon drilling rig is a semi-submersible, transportable, floating, flexibly oriented drilling rig that could work in sea depths of up to 10,000 feet which is approximately 3,000 meters.

During the explosion that occurred in April 2010, British Petroleum made several efforts to contain the damages made and to prevent further outbreaks of disasters.

Part of the changes was shifting from a blowout preventer that has a specialized valve to seal, manage, and monitor oil and gas wells in order to prevent blowouts to a containment dome (a crucial component of a system meant to control an oil well's underwater blowout).

Therefore, we can conclude that the British Petroleum (bp's) effort to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of regulatory policy change.

Introduction to Basic Microscopy. Microscopes are specialized optical instruments designed to produce magnified visual or photographic (including digital) images of objects or specimens that are too small to be seen with the naked eye.

Microscope are the important tools which are used by scientist. For example, in material science, medicine, mineralogy and microbiology.

Light microscope is able to send light. Light is being focused in a tight breath whereby that light passes through a sample which later it is able to create an image. This image passes to different lenses which magnifies it until it reaches the camera.

There are different types of microscope for example, Compound light microscope, Simple light microscope, and monocular microscope.

In simple light microscope only one lens which which is being used to magnify an object and it is not able to reach to a higher magnification.

In compound light microscope it uses two lenses to produce image. For example eyepiece lens and objective lens.

Answer:

Once the parachute is opened, the air resistance overwhelms the downward force of gravity. The net force and the acceleration on the falling skydiver is upward. ... The skydiver thus slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity.

When the skydiver is falling at a constant velocity after the parachute is open, acceleration is zero.

The wood can't do the same function as done by the water and glass in the same virtual experiment due to its different chemical composition.

The light will not pass through the wood due to its translucent behaviour that prevents light to pass through it as compared to water and glass which are transparent materials and light can easily pass through it.

So using wood as a bottom material instead of glass and water will not perform the same function as perform by water and glass in the same virtual experiment so we can conclude that wood can't perform the same function in the experiment.

Answer: It will increase the rate of reaction

Explanation:

An increase in enzyme or substrate concentration will increase the rate of reaction.

An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell.

Initially, an increase in substrate concentration leads to an increase in the rate of an enzyme-catalyzed reaction. As the enzyme molecules become saturated with substrate, this increase in reaction rate levels off.

The rate of an enzyme-catalyzed reaction increases with an increase in the concentration of an enzyme.

Hence, an increase in enzyme or substrate concentration will increase the rate of reaction.
