Answer:

Plates at our planet's surface move because of the intense heat in the Earth's core

Explanation:

Hopefully this helps, I believe in you! ^^

Answer/Explanation:

movement can be cause by the intense heat in the earth's core, which causes molten rock in the mantle layer to move.  it moves in a pattern called 'convection cell' which can form when the warm material rises, then cools, and eventually sink down.  then the process repeats (cooled, warms up and rises.. etc..)

Answer:

[tex] \huge 3.322 \times {10}^{ - 5} \: \: moles \\ [/tex]

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{2.00 \times {10}^{19} }{6.02 \times {10}^{23} } \\ \\ = 3.322 \times {10}^{ - 5} \: \: moles[/tex]

The molarity of a solution : 2.24

Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution

[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]

Where

M = Molarity

n = number of moles of solute

V = Volume of solution (L)

4.83 moles of NaCl in 2.16 L solution

n = 4.83

V = 2.16 L

Molarity :

[tex]\tt M=\dfrac{4.83}{2.16}=2.2361\rightarrow 3~sig~figs=2.24[/tex]

Answer:

NaCl has a smaller lattice energy compared to CaO

Explanation:

We have remember that lattice energy increases as the size of the ions in the ionic solid decreases. According to Oxford dictionary; lattice energy is "a measure of the energy contained in the crystal lattice of a compound, equal to the energy that would be released if the component ions were brought together from infinity."

We know that the larger the magnitude of charge on a cation the smaller in size the cation is and the size of anions increase from left to right in the periodic table. Hence Ca^2+<Na^+ and O^2- < Cl^-. Therefore the lattice energy of CaO is greater than that of NaCl.

Answer:

Lower Heart Rate

Athletes' heart rates tend to be lower than heart rates of non-athletes. A low resting heart rate is generally a sign of good cardiovascular fitness and efficiency. A well-trained athlete may have a normal resting heart rate of only 40 beats per minute, compared with the average heart rate that ranges from 60 to 100 beats a minute.

Lower Disease Risk

Athletic types may have better overall health and be less apt to develop certain diseases. Regular exercise boosts your immune system and lowers the risk of serious health conditions such as cancer and heart disease. Physical activity can also reduce the risk of type 2 diabetes and osteoporosis while helping to manage cholesterol levels and blood pressure. You gain about two hours of additional life expectancy for each hour of regular exercise, according to the American Heart Association.

Psychological Effects

Athletes may have better mental clarity and focus than non-athletes. Exercise increases the flow of oxygen, which has a direct impact on brain function, explains the American Heart Association. Exercise can help improve your memory and reduce negative feelings, such as anger, tension, anxiety and depression.

A comprehensive study of the academic performance of North Carolina high school student-athletes in North Carolina over a three-year period attests to the positive psychological effects of athletic capabilities. Researchers discovered obvious differences between athletes and non-athletes. The study of nearly 127,000 high school students found dropout rates were lower and grade point averages were higher in students who participated in sports. The study was led by Dr. Roger Whitley in collaboration with the North Carolina High School Athletic Association.

Motivated by Excellence

Athletes, especially competitive athletes, have high ambitions. It's a trait that allows them to persevere through setbacks and failures and to come out the other side stronger. Athletes are highly motivated individuals who set their sights on a prize and are single-minded in their pursuit of excellence. They are propelled by passion to become the best they can be and the benefits of that inner drive are a higher level of self-esteem and confidence.

Answer:

Valence electrons are the electrons in the outermost shell, or energy level, of an atom.example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴.

Answer:[tex][Kr]4d^{10}5s^25p^1[/tex]

Explanation:

The element Indium with atomic number 49 will have 49 protons and 49 electrons in it.

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom. The electrons are filled according to Afbau's rule in order of increasing energies and the nearest noble gas is Krypton with 36 electrons.

The electronic configuration in terms of noble gas configuration is:  

[tex]In:49:[Kr]4d^{10}5s^25p^1[/tex]

The noble-gas notation for the element indium is [Kr} 4d¹⁰5s²5p¹. The correct option is B.  [Kr] 5s2 4d10 5p1

From the question,

We are to write the electron configuration of the element Indium, using the appropriate noble gas notation.

The noble gas that comes before Indium (In) is Krypton (Kr). Therefore, the noble gas that will be used in the notation is Krypton.

Indium has an atomic number of 49 while Krypton has an atomic number of 36. This means we will fill in 13 more electrons.

The electron configuration for the element indium using the noble-gas notation is

[Kr} 4d¹⁰5s²5p¹

Hence, the noble-gas notation for the element indium is [Kr} 4d¹⁰5s²5p¹. The correct option is B.  [Kr] 5s2 4d10 5p1

Answer:

Aluminum even after being an active metal is used as a structural metal due to its toughness, high strength, lightweight, and resistance to the process of corrosion. It is resistant to corrosion as its reactivity gets suppressed due to the formation of an aluminum oxide film which is protective in nature, on its surface. Passivation is the term for the formation of the protective coating.

Answer

Incidentally, they all form dew but because grass is closer to the soil, which maintains heat longer than the air where tree leaves are found, you will find more condensation in that region. Also, higher up the wind and sun will allow faster evaporation which makes the dew less noticable on tree leaves.

Explanation:

Preferred objects of dew formation are thus poor conducting or well isolated from the ground, and non-metallic, while shiny metal coated surfaces are poor infrared radiators. ... If the wet soil beneath is the major source of vapor, however (this type of dew formation is called distillation), wind always seems adverse.

Answer: The lowest possible whole number coefficient for water is 1.

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble  water and remain in solid form are represented by (s) after their chemical formulas.

The balanced chemical reation for aqueous solutions of lithium hydroxide and acetic acid react to yield lithium acetate and water is:

[tex] LiOH(aq)+CH_3COOH(aq)\rightarrow CH_3COOLi(aq)+H_2O(l)[/tex]

Thus the lowest possible whole number coefficient for water is 1.

In the balanced equation for given reaction, the lowest possible whole number coefficient for water is one.

Stoichiometry of any reaction will tells about the relative amount of species presents before and after the chemical reaction.

Reaction between the lithium hydroxide and acetic acid is a neutralization reaction, as here lithium hydroxide is a base and acetic acid is a acid as a result of which it produces water molecule and lithium salt of acetate. And balanced equation for this will be represented as:

LiOH(aq) + CH₃COOH(aq)  CH₃COOLi(aq) + H₂O(l)

In the above equation all entities are present in equal amounts on both the sides and from the stoichiometry of the reaction it is clear that coefficient of water is 1.

Hence, 1 is the whole number coefficient for water.
