How are Parkinson's disease and ALS similar?
Both diseases are preventable.
Dementia is a symptom of both diseases.
Both diseases affect control of voluntary muscles.
Scientists understand the causes for both diseases.



HELP PLZ

Answers

Answer 1

Answer:

Both diseases affect the control of voluntary muscles.

Explanation:

Parkinson's disease is a progressive brain disease that affects movement. It affects the nerve cells that produce dopamine in the part of the brain called substantia nigra. The symptoms include shaking, stiffness, and difficulty with walking, balance, and coordination. Symptoms get worse with time, often leaving people with difficulty walking and talking.

ALS (amyotrophic lateral sclerosis) is a progressive nervous system disease that affects nerve cells in the brain and spinal cord. The first symptoms usually involve muscle weakness, and as the disease progresses, it results in the loss of muscle control.

Scientists don't know the exact cause of these diseases. As the cause is not known, there is no exact way to prevent them. There is no cure for them, either. The treatment is focused on the management of symptoms.

This is why the third option is the correct one.

What volume (in liters) of a 1.772 M BaCl2 solution is needed to obtain 123 g of BaCl2?

Answers

Answer:

Volume required = 0.327 L

Explanation:

Given data:

Volume in L = ?

Molarity of solution = 1.772 M

Mass of BaCl₂ = 123 g

Solution:

First of all we will calculate the number of moles of BaCl₂,

Number of moles = mass/molar mass

Number of moles = 123 g/ 208.23 g/mol

Number of moles = 0.58 mol

Now, given problem will solve by using molarity formula.

Molarity = number of moles / volume in L

1.772 M = 0.58 mol / Volume in L

Volume in L = 0.58 mol  / 1.772 M

Volume in L = 0.327 L

Consider the elements: Na, Mg, Al, Si, P.

a. Which element has the lowest second ionization energy?
b. Which element has the smallest atomic radius?
c. Which element is least metallic?
d. Which element is diamagnetic?

Answers

Answer:

The elements mentioned in the series are Na, Mg, Al, Si, and P. It can be seen that all these elements are located in the same period. The atomic number of the mentioned elements are Na-11, Mg-12, Al-13, Si-14, and P-15.

a) There will be an increase in the ionization energy with the increase in the element's atomic number across a period. More energy is needed to withdraw an electron from a completely occupied shell in comparison to an incompletely occupied shell.

The atomic number of Na is 11. When one electron is withdrawn from Na, it gets converted into the inert gas configuration of Ne. Thus, it will require more energy to withdraw the second electron from Na. Hence, Na exhibits the lowest second ionization energy.

b) Across the period, with an increase in the element's atomic number, the atomic radii reduces from left to right. Thus, P exhibits the smallest atomic radius.

c) The metallic nature of the elements reduces from left to right across a period in the periodic table. Thus, P is the least metallic element.

d) Diamagnetic signifies towards the element that exhibits pair electrons in its sub-shells. The electronic configuration of Mg is,

1s2 2s2 2p6 3s2

In Mg, no unpaired electrons are present, while all the remaining elements mentioned exhibit unpaired electrons in their valence shell. Thus, Mg is the diamagnetic element.

How much HCl exists in 347 mL of 0.48 M
solution of HCI?
Answer in units of mol.

Answers

Answer:

Number of moles of HCl = 0.17 mol

Explanation:

Given data:

Volume of solution = 347 mL

Molarity of solution = 0.48 M

Number of moles of HCl present = ?

Solution:

Formula:

Molarity = number of moles of HCl / volume in L

Volume in L:

347 mL× 1L / 1000 mL

0.347 L

Using the diagram below and the labels attached to it answer the following:
Transverse Wave Anatomy
1. Define the crest and trough of a wave and identify TWO points that represents a crest or a trough.
2. Define wavelength and identify TWO points that could be used in the diagram to measure it.
2. Determine the frequency of this wave if the waves the diagram represents occurred within 1 second.

Answers

Answer & Explanation:

Crest is a point in the cycle where maximum or peak amplitude exists. In another way, it is a point on the positive side of a wave where maximum amplitude exits. Trough is a point in the cycle where minimum amplitude exists.

Crest: points A and E

Trough: points C and J

Wavelength is the distance between two crests or two troughs. One example is distance between points A and E.

Frequency is 3 because there are 3 oscillations in 1 second (follow the line from beginning to point D, then D to G, the G to end).

I asked that question on my brainly account to answer your question so the people that answerd my question said this is right I HOPE IT IS!!

1. The highest point or crest of a wave is called a crest, and the lowest point or valley is called a trough.

2. The wavelength of a wave is the distance between its two successive crests or troughs.

3. The frequency of a wave is the number of complete cycles (peak or trough) that occur in a unit time.

1. The highest point or crest of a wave is called a crest, and the lowest point or valley is called a trough. On the other hand, in a transverse wave, the peak and trough will be represented by the places of highest displacement above and lowest displacement below the equilibrium position, respectively.

2. The wavelength of a wave is the distance between its two successive crests or troughs. However, wavelength can be determined by comparing any two locations that are separated by a full circle, such as two successive crests or troughs.

3. The frequency of a wave is the number of complete cycles (peak or trough) that occur in a unit time. If the waves in the diagram are visible within one second, then the frequency will be determined by how many complete cycles were visible within that time.

The electricity accounts of residents in a very small town are calculated as follows: v If 250 units or fewer are used, the cost is 2 cents per unit; v If more than 250 but not more than 800 units are used, the cost is $10 for the first 250 units and 5 cents for every unit in the excess of 250. v If more than 800 units are used, the cost is $35 for the first 800 units plus 10 cents for every unit in the excess of 800. v A basic service fee of $5 is charged, no matter how much electricity is used. Write a user-defined function program to calculate the fees of any electricity unit, and then write a command to calculate the fee of a resident who used 700 electricity units.

Answers

Answer:

For you first question about the defined function program:

if ( v ≤ 250 ) {

   set p to (5 + v*.02)

}

elseif ( 250 ≤ v ≤ 800 ) {

   set p to (5 + 2500 + (v - 250)*.02)

}

else {

   set p to (5 + 28000 + (v - 800)*.1)

}

This function will first check if the user has used how many units and decide which category that user falls into.

Then, it uses that information to execute a command to calculate how much money that user should pay for the electricity bill, factoring in the extra demands from the question.

For your second question:

(5 + 2500 + (700 - 250)*.02)

= (3000 + 450*.02)

= (3000 + 9)

= 3009

The customer should have paid 3009 dollars.

The diameter of a helium atom is about 1 3 102 pm. Suppose that we could line up helium atoms side by side in contact with one another. Approximately how many atoms would it take to make the distance from end to end 1 cm

Answers

Answer:

1 × 10⁸ He atoms

Explanation:

Step 1: Given data

Diameter of a helium atom (d): 1 × 10² pmTotal distance to be covered (D): 1 cm

Step 2: Convert "d" to meters

We will use the conversion factor 1 m = 10¹² pm.

1 × 10² pm × (1 m / 10¹² pm) = 1 × 10⁻¹⁰ m

Step 3: Convert "D" to meters

We will use the conversion factor 1 m = 100 cm.

1 cm × (1 m / 100 cm) = 0.01 m

Step 4: Calculate the number of atoms of He required

We will use the following expression.

D/d = 0.01 m / 1 × 10⁻¹⁰ m = 1 × 10⁸

One variable linear equation is an equation that has a variable and the exponent number is one.  

Can be stated in the form:  

[tex]\large{\boxed{\bold{ax=b}}[/tex]

or  

ax + b = c, where a, b, and c are constants, x is a variable  

The parallelogram has total angle of 360°.

The value of each of the 4 angles of the parallelogram :

1. x°

2. x°

3. x+10°

4. 59°

The sum of the four angles of this parallelogram is :

[tex]\tt x+x+x+10+59=360[/tex]

So that the mathematical equation becomes (by combining the like terms) :

[tex]\tt 3x+69=360\\\\3x=291\\\\x=97[/tex]

So the value of the four angles (by entering the x value)

1. 97°

2. 97°

3. x+10=97+10=107°

4. 59°

A chemist determines by measurements that moles of bromine liquid participate in a chemical reaction. Calculate the mass of bromine liquid that participates. Be sure your answer has the correct number of significant digits.

Answers

Answer:

This question is incomplete as it lacks the number of moles of Bromine. The complete part is as follows: 0.0900 moles of bromine liquid participate in a chemical reaction.

The answer is 7.191g

Explanation:

The number of moles in a substance can be calculated thus;

moles = mass/molar mass

Atomic mass of Bromine = 79.9g/mol

According to the question, the chemist determines by measurements that 0.0900 moles of bromine liquid participate in a chemical reaction. To calculate the mass of bromine liquid that participates, we say;

Mass = moles × molar mass

Mass = 0.0900 × 79.9

Mass = 7.191g

Therefore, 7.191g of Bromine will participate in the chemical reaction.

D. Nonmetals with nonmetals, because of difference in electronegativity is below 1.7 ​

Answers

Answer:

D. Nonmetals with nonmetals, because of difference in electronegativity is below 1.7 ​

Explanation:

The types of atoms that typically form covalent bonds are non-metals with non-metals because of the difference in their electronegativity which is below 1.7.

In some instances, the difference can even be zero when dealing with homonuclear substances.

Covalent bond are formed between two or more atoms having low electronegativity differences between them. Each of the atoms share their valence electrons to be able to mimic the noble gases. The participating atoms will put down an unpaired electron to be used in forming a shared pair of electrons between them.
