why is it important foe scientists to know how many valence electrons a given element has

Answers

Because the number of valence electrons of an element determines the properties and in particular the reactivity of that element.

In fact, elements of the first group (i.e. only one valence electron) have high reactivity, because they can easily give away their valence electron to atoms of other elements forming bonds. On the contrary, elements of the 8th group (noble gases) have their outermost shell completely filled with electrons, so they do not have valence electrons, and they have little or no reactivity at all.

Explain what happens to the pitch of a cell phone ringing when the amplitude of a sound wave increases.

Answers

As the amplitude of a sound wave increases the pitch of the ringing would be much higher (like if you were to inhale helium.. just with a phone)

the pitch of the cell phone ringing will remains same when the amplitude of a sound wave increases.

The pitch of a sound wave depends on its frequency. more frequency means higher pitch and less frequency means lower pitch. The amplitude of wave is the maximum displacement of the particles of the medium from their mean positions. Increase in amplitude will increase the loudness and not the pitch. So the pitch remains same as the amplitude of sound wave is increased.

if a glacier is in equilibrium, where ablation is equal to the accumulation, what occurs in the terminus or 'snout'

Answers

The answer is : neither erosion nor deposition occurs.
If a glacier is in equilibrium, where ablation is equal to the accumulation, either erosion nor deposition occurs in the terminus or 'snout'. It stops depositing rocks, the snow would stop falling at the terminu, the temperature would rise, It is neither advancing nor retreating anymore.

If a glacier is in equilibrium, its terminus remains stable as ice loss from ablation equals ice gain from accumulation. The glacier's terminus does not advance or retreat under these conditions.

If a glacier is in equilibrium, it means that the ablation (loss of ice) is equal to the accumulation (gain of ice). The point where this balance is achieved is the equilibrium line. If the glacier is in equilibrium, the terminus or 'snout' of the glacier remains at a stable position. While the ice continues to flow downslope, the position of the terminus does not advance or retreat because the amount of ice being lost to ablation is equal to the amount being gained through accumulation.

What is an ion found in a glass of water

Answers

Answer:

[tex]H^{+}[/tex] ion and [tex]OH^{-}[/tex] ions.

Explanation:

As we notice the glass of water, in this observation we find that the glass also made up of sodium silicate which will give us oxygen ion.

And the water which is present in the glass will break into the hydroxyl ion and [tex]H^{+}[/tex] ion .

Therefore, glass of water contains [tex]H^{+}[/tex] ion and [tex]OH^{-}[/tex] ions.

An ion commonly found in a glass of water is the hydrogen ion (H+).

How does this happen?

When water molecules dissociate, a small fraction of them break apart into hydrogen ions (H+) and hydroxide ions (OH-). These ions are responsible for the water's ability to conduct electricity.

The presence of hydrogen ions in water makes it slightly acidic, with a pH below 7. However, the concentration of hydrogen ions in pure water is very low, making it close to neutral on the pH scale. The balance of these ions is essential for maintaining the pH and chemical properties of water.

A longitudinal wave is a wave that vibrates in the same direction as its direction of propagation. In a longitudinal wave, the direction of particle displacement is parallel to the direction of wave motion. The correct answer is "In a longitudinal wave, particle displacement is parallel to the direction of wave motion."

This means that as the wave moves forward, the particles of the medium through which the wave travels move back and forth along the same line as the wave's direction of propagation. This type of wave is often referred to as a compressional wave because it causes the particles of the medium to be compressed and then expanded as the wave passes through. An example of a longitudinal wave is sound waves. These waves move through the air by compressing and expanding the air particles along the same direction as the wave's motion, producing changes in air pressure that our ears detect as sound. Therefore, the correct answer is "In a longitudinal wave, particle displacement is parallel to the direction of wave motion."

the answer to the question is d

Answer 1) For calculating ΔU;

We can use the expression for the first law of thermodynamics which is,

ΔU = Q + W

Where ΔU is the Change in internal energy, Q is heat added to the system and W is the work done on the system.

As, Q = + 51 KJ and W = -15 KJ.

So, ΔU = 51 -15 = 36 KJ.

Hence, ΔU = 36 KJ

Answer 2) Using the same first law of thermodynamic equation for calculating ΔU (Internal Energy o the system) ;

ΔU = Q + W;

Given, Q = + 100 KJ and W = - 65 KJ

On substituting the values in the above equation we get,

ΔU = 100 - 65 = 35 KJ

Therefore, ΔU = 35 KJ

Answer 3) Using the same first law of thermodynamic equation for calculating ΔU (Internal Energy o the system) ;

ΔU = Q + W;

Given here, Q = - 65 KJ and W = - 20 KJ

On substituting the above values in the equation we get,

ΔU = -65 -20 = - 85 KJ

Therefore, ΔU = - 85 KJ for this system.

Answer 4) According to the answers in 1), 2) and 3) it can be seen that there has been change in the internal energies of the system for all, but some are positive changes and some are negative.

As per the definition of the internal energy, when the system does work on its surroundings, energy is found to be lost, and E is observed to be negative; and when the surroundings do work on the system, the internal energy of the system becomes larger, converting E into positive.

So, it is clear that in case 3) the system did work on the surroundings as E value is found to be negative, rest have positive E values.

If a forklift raises a 76-kg load a distance of 2.5 m, about how much work has it done?

Answers

Final answer:

To calculate the work done by the forklift, we need to find the force exerted by the forklift and multiply it by the distance it raises the load. The force exerted by the forklift can be found using the formula Force = mass x gravity. The work done by the forklift is approximately 1864 Joules.

Explanation:

To calculate the work done by the forklift, we can use the formula:

Work = Force x Distance

First, we need to find the force exerted by the forklift. Since the load has a mass of 76 kg, we can use the formula:

Force = mass x gravity

where gravity is approximately 9.8 m/s^2 (acceleration due to gravity). So, the force exerted by the forklift is:

Force = 76 kg x 9.8 m/s^2 = 745.6 N

Now, we can calculate the work done by the forklift:

Work = 745.6 N x 2.5 m = 1864 J

Therefore, the forklift has done approximately 1864 Joules of work.

When sunlight strikes oil on the surface of water, a variety of colors are observed. What is the best explanation for this observation?

Answers

The reason is light scattering.

The sunlight that falls on oil we perceive to be white in color. But in fact that light is made of all colors (purple, blue, red, green, yellow, orange, red...). All these colors have same intensity and come under same angle so they combine and give white light.

Each of these colors has different wavelength and different frequency. Depending on the wavelength of a color it refracts on oil under different angle. After exiting molecule of oil all color exit at different angle. This is reason that the do not combine and do not give white light. We see them as individual colors.

Which tubes will test positive for Benedict's test and which will test positive for Iodine test?

Answers

Disaccharides are positive in Benedicts test as it is a reducing sugar. Any animal product testing positive for starch on the lodine test may be contaminated or mixed with plant product. The positive control for the iodine test was the starch solution.

If this helped, please give me brainliest :)

Final answer:

Benedict's test is used to identify reducing sugars and results in color changes from blue to green, yellow, or red. The Iodine test, on the other hand, identifies starch by changing from a brown iodine color to a blue-black color.

Explanation:

In conducting laboratory tests, two popular assays are the Benedict's test and the Iodine test. The Benedict's test is used to detect the presence of reducing sugars, like glucose, in a sample. If a tube turns from blue (the color of the original Benedict's solution) to green, yellow or red, it indicates a positive result - the various colors represent different levels of sugar concentration.

Conversely, the Iodine test is used to detect the presence of starch in a sample, such as in a potato or bread. In a positive Iodine test result, the originally brown iodine solution will change to a blue-black color upon interaction with starch.

Therefore, tubes containing reducing sugars (like glucose or lactose) will test positive in a Benedict's test, and tubes containing starch will test positive in an Iodine test.

Suppose you increase your walking speed from 6 m/s to 14 m/s in a period of 1 s. What is your acceleration?

Answers

a = delta v over delta t delta v is calculated with final velocity less initial velocity so delta v is 14 - 6 that is 8m/s and delta t is calculated with final time less initial time as initial always is 0 then is 1 - 0 that is 1 then a = 8m/s over 1 that is 8 then the acceleration is 8m/s^2 (remember that is squared.)

Answer:
acceleration = 8 m/s²

Explanation:
Acceleration is defined as the rate of change of velocity.
This means that:
acceleration = [tex] \frac{v2 - v1}{t2 - t1} [/tex]
We are given that:
V2 = 14 m/sec
V1 = 6 m/sec
We are also given that the duration is 1 sec, this means that:
t2 = 1 sec
t1 = 0 sec

Substitute with the givens in the above equation to get the acceleration as follows:
acceleration = [tex] \frac{14-6}{1-0} [/tex] = [tex] \frac{8}{1} [/tex] = 8 m/s²

which has a higher acceleration:a 10kg object acted upon with a net force of 20N or an 18kg object acted on by a net force of 20N

Answers

Answer: The acceleration of 10 kg object is greater than that of 18 kg object.

Explanation:
According to Newton's Second law:
F = ma --- (A)

Let's find the acceleration for both 10 kg and 18 kg objects!
The net force on both of these masses = F = 20N

(1) Acceleration of 10 kg object
Mass = m = 10 kg
Plug in the values in equation (A):
20 = 10 * a
Acceleration = a = 2 m/s^2

(2) Acceleration of 18 kg object
Mass = m = 18 kg
Plug in the values in equation (A):

20 = 18 * a
Acceleration = a = 1.11 m/s^2

2 > 1.11; therefore, 10 kg object has the higher acceleration compared to the acceleration of the 18 kg object.

Explanation:

The expression of the applied force in terms of mass and acceleration by using Newton's second law is as follows;

F= ma

Here, m is the mass of the object and a is the acceleration of the object.

Calculate the acceleration of a 10 kg object acted upon with net force of 20 N in the above expression.

Put m= 10 kg and F= 20 N in the above expression.

20= (10)a

a= 2 m/s^2

Calculate the acceleration of a 18 kg object acted upon with net force of 20 N in the above expression.

Put m= 18 kg and F= 20 N.

20= (18)a

a= 1.11 m/s^2

Therefore, the acceleration of a 10 kg object acted upon with net force of 20 N is greater than the acceleration of a 18 kg object acted upon with net force of 20 N.

What are fundamental forces?

At the considerable fundamental level, all the forces in the existence (as currently understood) are emanated from only four forces:

The gravitational force

The electromagnetic force

The weak nuclear force

The strong nuclear force

An object's mass is proportional to its weight because weight is determined by the gravitational force acting on an object, which is directly proportional to the object's mass.

Specifically, an object's weight is equal to its mass multiplied by the acceleration due to gravity.

Therefore, if the mass of an object increases, its weight will increase proportionally, and if the mass decreases, the weight will decrease proportionally as well.

Therefore, the correct answer would be option (A) proportional to.
