Answer:

The bonds that exist between their atoms and molecules differ on an atomic scale.

Explanation:

The three basic states of matter are solid, liquid, and gas. The major difference between them is the strength of the bonds that hold their molecules together. This affects the way that the molecules interact with each other.

The intermolecular forces binding solids together are very strong. This makes solids rigid and not able to move about freely, but rather, only able to vibrate about a mean position.

The intermolecular forces binding liquid atoms together are a lot weaker than that of solids. This makes liquids able to flow.

The intermolecular forces binding gas molecules together are the weakest. As a result, the gases can move about freely and occupy no definite volume.

The speed of the turtle is 9.41 centimeters per second.

We know that

Speed of small turtle = 566 furlong/fortnight

1 furlong = 20,116.8 cm

And,

1 fortnight = 1,209,600 seconds

So,

The speed of the turtle is 9.41 centimeters per second.

Answer:

202,020 pennies

Explanation:

The amount of pennies in 1 dollar is 100.

Basically, you just multiply the whole dollar amount (2020) by 100 and then add 20 to find the amount of pennies.

(2020)(100)+20= 202,000+20= 202,020 pennies.

Answer:

202,040 pennies

Explanation:

$1 is equal to 100 so just multiply 100 by 2,020 and then you can add the extra 20 cents

Answer:

Tables and charts are both used to represent data. However, the manner and circumstances in which each is used, distinguishes them from one another. Tables represent facts and figures in a row and column format which makes the data easier and faster to read and compare. On the other hand, charts represent data in a more graphical manner which may include lines, bars and circles.

Explanation:

I Hope This Helps! ^^

Answer:

A pie chart is a graph in which a circle is divided into sectors, each of which represents a percentage of the overall. Its goal is to show percentages at a specific time in history. Pie charts, unlike bar and line graphs, do not illustrate changes over time. Tables sort the data rationally in a row-and-column format, much to spreadsheets. Tables are used to arrange information that is too detailed or complex to be fully described in a text, allowing the reader to see fast results. They can be used to highlight data trends or patterns, as well as to remove numeric data from a document to make it more readable.

Answer:

1425 mmHg.

Explanation:

The following data were obtained from the question:

Initial volume (V1) = 1.5 L

Initial pressure (P1) = 1 atm

Final volume (V2) = 0.8 L

Final pressure (P2) =?

Next, we shall determine the final pressure of the gas by using the Boyle's law equation as follow:

P1V1 = P2V2

1 × 1.5 = P2 × 0.8

1.5 = P2 × 0.8

Divide both side by 0.8

P2 = 1.5/0.8

P2 = 1.875 atm

Finally, we shall convert 1.875 atm to mmHg.

This can be obtained as follow:

1 atm = 760 mmHg

Therefore,

1.875 atm = 1.875 × 760 = 1425 mmHg.

Therefore, the new pressure of the gas is 1425 mmHg.

Answer:

0.44 L.

Explanation:

Density of nickel(II) chloride = 29.8 g/dL.

Mass of nickel(II) chloride = 131 g

Volume of nickel(II) chloride =?

Next, we shall convert 29.8 g/dL to g/L. This can be obtained as follow:

Recall:

1 g/dL = 10 g/L

Therefore,

29.8 g/dL = 29.8 x 10 = 298 g/L

Therefore, 29.8 g/dL is equivalent to 298 g/L.

Finally, we shall determine the volume of nickel(II) chloride as follow:

Density of nickel(II) chloride = 298 g/L

Mass of nickel(II) chloride = 131 g

Volume of nickel(II) chloride =?

Density = mass /volume

298 = 131/Volume

Cross multiply

298 x Volume = 131

Divide both side by 298

Volume = 131/298

Volume = 0.44 L

Therefore, the volume of of nickel(II) chloride is 0.44 L

[tex]\boxed{\text{6.95 u; Li}}[/tex]

Explanation:

1. Atomic mass of T

To get the atomic mass of T, you calculate the weighted average of the atomic masses of the isotopes.

That is, you multiply the atomic mass of each isotope by a number representing its relative importance (e.g.., its percent of the total).

[tex]\begin{array}{ccrcr}\textbf{Atom} & \textbf{Mass/u} &\textbf{Percent} & \textbf{Calculation}& \textbf{Result/u}\\^{6}\text{T}& 6.02 & 7.42 & 6.02 \times 0.0742 & 0.45\\^{7}\text{T}& 7.02 & 92.58 & 7.02 \times 0.9258& 6.50\\& & &\text{TOTAL } = &\textbf{6.95}\\\end{array}[/tex]

Answer:

Newton's First Law of Motion states that in order for the motion of an object to change, a force must act upon it. This is a concept generally called inertia.

Newton's Second Law of Motion defines the relationship between acceleration, force, and ​mass.

Newton's Third Law of Motion states that any time a force acts from one object to another, there is an equal force acting back on the original object. If you pull on a rope, therefore, the rope is pulling back on you as well.
