Rubbing two objects together may cause large number of electrons to be transferred from one object to the other.a. Trueb. False

Answers

Answer 1

The statement "Rubbing two objects together may cause a large number of electrons to be transferred from one object to the other" is True.

When we rub two distinct objects together, we increase the contact area between them, which also means that the friction level rises. When two different substances are rubbed against one another, an exchange of electrons takes place from one substance to the other. Because of this, one of the subjects loses electrons and becomes positively charged, while the other subject gains electrons and becomes negatively charged Triboelectric Charging is another name for this process.

Now, if the contact area of two different rubbing objects were to get larger, there would be a greater amount of friction, which would result in a greater number of electrons being transferred from one object to the other.

how could a molecule from plants that blocks the connection between nerves and muscles be useful as a pharmaceutical?

Answers

It could be used as a muscle relaxant.

A muscle relaxant is a drug which affects skeletal muscle function and they also decreases the muscle tone. They are used to alleviate symptoms such as muscle spasms, pain, as well as hyperreflexia. The term "muscle relaxant" is used to refer to two major therapeutic groups like neuromuscular blockers and spasmolytics. Neuromuscular blockers are those that generally act by interfering with transmission at the neuromuscular end plate and also they have no central nervous system (CNS) activity. They are generally used during surgical procedures and in intensive care and emergency medicine because they causes temporary paralysis. Spasmolytics, which are known as "centrally acting" muscle relaxant, are used to alleviate musculoskeletal pain as well as spasms and they are know to reduce spasticity in a variable  neurological conditions. Sometimes both neuromuscular blockers and spasmolytics are often grouped together as muscle relaxant. But sometimes the term is commonly used to refer to spasmolytics only.

Choose the antimicrobial category that ismost selectively toxic.-antimicrobials that inhibit cell wall synthesis -antimicrobials that inhibit protein synthesis -antimicrobials that interfere with nucleicacid structure and function -antimicrobials that inhibit folic acid synthesis -antimicrobials that interfere with cell membrane structure and function

Answers

Antimicrobial agents can be classified into different categories based on their target mechanism of action.

The selective toxicity of an antimicrobial refers to its ability to target the pathogenic microorganisms without causing harm to the host. This is because the cell wall of bacteria differs significantly from the cell membrane of human cells, allowing for targeted inhibition without affecting human cells. Among the various antimicrobial categories, those that inhibit folic acid synthesis are considered to be the most selectively toxic. This is because the antimicrobial depend on folic acid for their survival, while the host has alternative pathways to synthesize folic acid. As a result, antimicrobials that inhibit folic acid synthesis are able to specifically target the pathogens, minimizing the risk of adverse effects on the host.

in organic architecture, which of the follow¬ing is true? * (a) form follows function. (b) function follows form. (c) function is not important to form. (d) form and function are one.

Answers

In organic Architecture (d) form and function are one is True.

Organic architecture is a design philosophy that emphasizes the harmonious relationship between buildings and their natural surroundings. It is based on the idea that buildings should be integrated into the landscape, rather than imposing themselves upon it.

Organic architecture seeks to create structures that are not only functional, but also aesthetically pleasing and in harmony with their environment.

Organic architects believe that form and function should be inseparable and that a building's design should be driven by its intended use. They believe that a building's form should emerge naturally from its function, rather than being imposed upon it.

This philosophy is in contrast to the "form follows function" approach, which prioritizes function over form and sees form as a secondary consideration. In organic architecture, form and function are not considered to be separate entities, but rather two sides of the same coin.

The end goal is to create buildings that are not only functional and efficient, but also beautiful and harmonious with their natural surroundings.

what causes skin to tan? what causes skin to sunburn?

Answers

Sunburn, on the other hand, is caused by overexposure to UV light, which damages the skin cells and causes inflammation. Skin tanning is caused by exposure to ultraviolet (UV) light from the sun.

Skin tanning is a natural response of the skin to protect itself from damage from ultraviolet (UV) radiation from the sun. UV light stimulates the skin to produce more melanin, the pigment responsible for skin color. As melanin levels increase, the skin darkens, giving it a tan appearance. This increased melanin helps to absorb and scatter UV light, reducing its harmful effects.

However, it is important to note that while a tan may look attractive, it is actually a sign of skin damage and does not provide complete protection against skin cancer. Sunburn, on the other hand, is a painful and damaging result of overexposure to UV light. When the skin is exposed to too much UV radiation, it can cause damage to the DNA in skin cells, leading to inflammation and redness. Sunburn can increase the risk of skin cancer and other skin problems in the future, so it is important to take precautions such as wearing protective clothing and using sunscreen when spending time in the sun.

You mix 2 moles of hbr with 3 moles of koh in enough water to make 1 l of solution. How much kbr do you expect to make?.

Answers

Taking into account the definition of pH and pOH, limiting reagent and reaction stoichiometry, the pH of the final solution is 14.

Limiting reagent and excess of moles.

Hydrobromic acid and potassium hydroxide react in a 1:1 mole ratio to produce aqueous potassium bromide and water, following the reaction:

HBr + KOH → KBr + H₂O

So, if you mix equal numbers of moles of each reactant, both the acid and the base will be completely consumed.

But in this case you mix 2 moles of HBr with 3 moles of KOH.

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

In this case, as the reaction has a 1:1 mole ratio hydrobromic acid will act as the limiting reagent, and it will be completely consumed before all the moles of potassium bromide are consumed, so there will be an excess of moles of potassium bromide.

After the reaction is complete, the resulting solution will contain an excess of moles of potassium bromide calculated as, considering that when 2 moles of hydrobromic acid are consumed, 2 moles of potassium hydroxide are consumed:

3 moles that you had at the beginning of the reaction - 2 moles that react= 1 mole of potassium bromide

Definition of molarity

Molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]Molarity[/tex] [tex]$=\frac{\text { numberofmoles }}{\text { volume }}$[/tex]

Molarity of potassium bromide

In this  case you know:

number of moles= 1 mole of potassium bromide

volume= 1 L

So, the concentration of potassium bromide is calculated as:

[tex]Molarity[/tex][tex]\frac{1 \text { mole }}{1 L}=1 \frac{\text { mole }}{L}$[/tex]

Definition of pH

pH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

The pH is defined as the negative base 10 logarithm of the activity of hydrogen ions, that is, the concentration of hydrogen ions or H₃O⁺:

pH= - log [H⁺]= - log [H₃O⁺]

Definition of pOH

pOH is a measure of hydroxyl ions in a solution and is expressed as the logarithm of the concentration of OH⁻ ions, with the sign changed:

pOH= - log [OH⁻]

Relationship between pH and pOH

The following relationship can be established between pH and pOH:

pOH + pH= 14

Calculation of pH in this case

In this case, the concentration of hydroxide anions are delivered to the solution by the potassium hydroxide in a 1:1 mole ratio.

So, being the concentration of potassium bromide 1 , the concentration [OH⁻]= 1 .

Replacing in the definition of pOH, then the pOH is:

pOH= - log 1 .

Solving:

pOH= 0

Finally, replacing in the relationship between pH and pOH:

pH + 0=14

pH=14
