The answer would be for this question will be hyperpolarize; the driving force for potassium to exit the cell increases.
The resting potential of a neuron that is submerged in a solution with zero extracellular potassium will hyperpolarize because the driving force for potassium to exit the cell increases.
Hyperpolarization is the process in which the membrane potential looks good on more negative at a specific spot on the neuron's membrane where as depolarization is when the membrane potential became less negative.
At this point at which the neuron is hyperpolarized, in the middle of –70 mV and –75 mV. After hyperpolarization the potassium passage encloses and the natural permeability of the neuron to sodium and potassium permits the neuron to come back to its recline potential of –70 mV.

Which test tube has the largest amount of precipitate? record the ratio of cuso4 to na2s used. what is the indicated by the maximum amount of particiapation
The third test tube has the largest amount of precipitate. The correct ratio for this reaction is 1:1.
What do you mean by test tube?
Test tubes intended for the general chemical work are usually made of glass, and for its relative resistance to heat. Tubes made from the expansion-resistant glasses, mostly borosilicate glass or fused quartz, can withstand high temperatures up to several hundred degrees Celsius.
Chemistry tubes are available in a multitude of the lengths and widths, typically from 10 to 20 mm wide and 50 to 200 mm long. The top often features a flared lip to aid pouring out contents.
A chemistry test tube typically has flat bottom, a round bottom, or a conical bottom. Some test tubes are made to accept a ground glass stopper or screw cap. They are often provided with small ground glass or white glaze area near the top for labelling with a pencil.
Test tubes are widely used by the chemists to handle chemicals, especially for qualitative experiments and assays. Their spherical bottom and vertical sides reduce mass loss when pouring, make them easier to wash out, and allow convenient monitoring of contents. The long, narrow neck of the test tube slows down the spreading of gases to the environment.
Test tubes are convenient containers for heating the small amounts of liquids or solids with a Bunsen burner or alcohol burner. The tube is usually held by its neck with clamp or tongs. By tilting tube, the bottom can be heated to hundreds of degrees in the flame, while the neck remains relatively cool, possibly allowing vapors to condense on its walls. A boiling tube is large test tube intended specifically for boiling liquids.

Nuclear fusion reactions inside the cores of stars convert light elements into heavier ones and release enormous amounts of energy. at what point does the process of fusion begin in a star?
In a process known as nucleosynthesis, fusion powers stars and creates nearly all elements. As a main-sequence star, the Sun generates its energy through the nuclear fusion of hydrogen nuclei into helium. Each second, the Sun's core fuses 620 million metric tons of hydrogen and produces 616 million metric tons of helium. The fusion of lighter elements in stars has energy and mass that is always present.
How does the Sun get its energy from nuclear fusion reactions?Nuclear fusion reactions power the Sun and other stars. A fusion reaction occurs when two light nuclei combine to form a single heavier nucleus. Because the total mass of the resulting single nucleus is less than the mass of the two original nuclei, the process releases energy. The remaining mass is converted into energy.
Why is it claimed that nuclear fission in stars releases all elements?The occurrence of nuclear fusion in stars causes energy to be released from the core in the form of heat or light, or sometimes another nucleus. According to this, nuclear fission in stars virtually releases all elements.

you use 25% ethyl acetate (an ester) in hexane to run a tlc and obtain a single round spot with an rf of 0.9 for the main compound. what would you do?conclude that the sample is pure.assume that tlc will be useless and find a different way to see if the sample if pure.try a completely different set of solvents, as ethyl acetate and hexanes will never work.try 10% ethyl acetate to see the results.try 35% ethyl acetate to see the results.
Try 35% ethyl acetate to see the results, this is because adding more ethyl acetate will increase the polarity and the compounds get easily separated.
In TLC, the polarity between the stationary phase and mobile phase is the basis for mixture separation. In accordance with the "like dissolves like" principle, polar substances can only dissolve in other polar substances, while non-polar substances may only dissolve in other non-polar substances. Consequently, when two compounds with different levels of polarity are present, the more polar molecule interacts with silica more strongly and is therefore better able to displace the mobile phase from the accessible binding sites. The less polar compound thus travels higher up the plate (resulting in a higher Rf value).
However, changing the mobile phase to a more polar solvent or mixture of solvents improves binding to the polar plate and thereby displacing solutes from it, causing all compounds on the TLC plate to rise higher up the plate. It is a prevalent belief that although "weak" eluents hardly move the examined compounds, "strong" eluents drive them up the plate.
Therefore, all compounds move longer and have a larger Rf when a mobile phase is made more polar than it was originally.
Since hexane has a non-polar property while ethyl acetate has a polar property. As a result, adding 35% ethyl acetate will enhance the polarity, making it easier to separate the compounds.

27.20cm3 of a NaOH solution was titrated with 25cm3 of a 0.75mol/dm3 HNO3. What was the concentration of the NaOH solution
The Concentration of NaOH solution when NaOH solution was titrated with 25cm3 of a 0.75mol/dm3 HNO3 is 26.4 g/dm3.
Titration is a method of chemical analysis where the quantity of a sample's constituents is determined by adding a precisely measured amount of a different substance to which the desired constituent will react in a specific, known proportion.Given,
Volume of HNO3 is 25cm³ = 0.025 dm³
Amount of solute in mol = concentration in mol/dm3 × volume in dm3
Amount of HNO3 = 0.75 × 0.025 = 0.018 mol
The balanced equation is: NaOH(aq) + HNO3(aq) → NaNO3(aq) + H2O(l)
So the mole ratio NaOH:HNO3 is 1:1
Therefore 0.018 mol of NaOH reacts with 0.018 mol of HNO3.
Volume of sodium hydroxide solution 27.20cm³ =
0.027 dm³.
Concentration = 0.018 / 0.027 = 0.66 mol/ dm³
Relative formula mass of NaOH= 40
Mass = relative formula mass × amount
Mass of HCl = 40 × 0.66
= 26.4
So concentration = 26.4 g/dm3

Upon addition, an alkoxide is created. Water then protonates the alkoxide, regenerating a hydroxide ion and a primary gem-diol. When two neighboring alkyl groups are linked to a carbon atom, the result is a secondary gem-diol. This would result from the substrate molecule was ketone. When an alcohol and an aldehyde combine to generate a new compound, a hemiacetal is created. This compound has a carbon atom attached to both an ether and hydroxyl group.

When sodium chloride is dissolved in water, the temperature of the resulting solution is lower than the temperature of the water before the salt dissolves. How can this result be explained based on bond breaking in bond making that is occurring?
Homolysis is the process of breaking a covalent single bond when, as in the first example, one of the shared pair's electrons is still present with each fragment. Heterolysis is the term for when a bond breaks while still having one fragment and both of the sharing pair's electrons, as in the second and third examples.
How can this result be explained based on bond breaking in bond making that is occurring?
Due to electrical charges and the fact that both water and salt molecules are polar, with positive and negative charges on opposite sides of the molecule, salt dissolves in water at the molecular level.
The chloride ion is negatively charged, while the sodium ion is positively charged, which is why the bonds in salt compounds are referred to as ionic. A water molecule is also ionic in nature, but the link is covalent because two hydrogen atoms place their positive charges on opposite sides of the oxygen atom, which has a negative charge. Water's covalent bonds are more powerful than salt molecules' ionic bonds, so when salt is combined with water, the salt dissolves.
The negatively charged side of the water molecules is drawn to the positively charged sodium ions, whereas the positively charged side is drawn to the negatively charged chloride ions. In essence, a tug-of-war takes place, with the water molecules coming out on top. The ionic link that held sodium and chloride ions together is broken when water molecules force the ions apart. As seen in this picture, the sodium and chloride atoms are encircled by water molecules after the salt compounds are separated. After that, the salt dissolves and forms a homogenous solution.
