The term which best describes the repeated arrangement of the same molecule is: D. extended structure.
An atom can be defined as the smallest unit which comprises the matter that forms all chemical elements. Thus, atoms are typically the fundamental building blocks of matter and as such determines (defines) the structure of a chemical element.
Generally, atoms are typically made up of three (3) distinct particles and these are;
Protons.Neutrons.Electrons.In Chemistry, a molecule can be defined as a group of two or more atoms that are chemically bonded together by means of shared electrons and represents the smallest fundamental unit of a substance or chemical compound.
Basically, when the same molecule are arranged repeatedly it is typically referred to as an extended structure.
In conclusion, the term which best describes the repeated arrangement of the same molecule of a chemical compound or substance is an extended structure.

The density of gold is 19.3 g cm³. What is the mass of a bar of gold in Kg that measures 6 cm x 4 cmx to 2 cm ?
solve
Answer: 0.9264 kg
Explanation: [I'll use "cc" for cubic centimeter, instead of cm^3.
The volume is 6cm*4cm*2cm = 48 cm^3 (cc).
Density of Au is 19.3 g/cc
Mass of gold = (48 cc)*(9.3 g/cc) = 926.4 grams Au
1 kg = 1,000 g
(926.4 grams Au)*(1 kg/1,000 g) = 0.9264 kg, 0.93 kg to 2 sig figs
At gold's current price of $57,500/kg, this bar is worth $53,268. Keep it hidden from your lab partner (and instructor).
The centrifugal force which tends to throw the electrons out it's orbit as stated with mass moving velocity in an orbit of radius is given as what?
Answer:
Mass, velocity, and radius are all related when you calculate centripetal force. ... The equation shows that if you increase mass or speed, you'll need a larger force; if you decrease the radius, you're dividing by a smaller number, so you'll also need a larger force.

tides occurs in oceans but not in lakes.why?
Answer:
Explanation:
Tides occur in the ocean but nit in lakes because an ocean is a free flowing body of water that can travel a large area of the globe while a lake or pond only covers a small area of the earth so it is not affected by gravity as violently and in turn, prevents the formation of tides.
Bonds Quick Check
Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible? (1 point)
o Metals have low electronegativity, so they are conductive because they pass charges easily.
Two metals bonded together are going to be more conductive than a metal bonded with a
nonmetal.
O An attraction between a positive charge and a negative charge is created.
The bonds can shift because valence electrons are held loosely and move freely.
Answer:
The bonds can shift because valence electrons are held loosely and move freely.
Explanation:
The metallic bonds are responsible for many properties of metals, such as conductivity, the reason is, the bonds can shift because valence electrons are held loosely and move freely.
Metallic bond is the force that binds two metallic substances together.
The valence electron in this type of bond are always in constant motion, causing the electron to move from one neighboring atom to another.
This free electron character of the valence electron of the metallic bond is responsible for the high electrical conductivity of metals.
The valence electrons are always free to move when an electrical field is applied in the metal.
Thus, the metallic bonds are responsible for many properties of metals, such as conductivity, the reason is, the bonds can shift because valence electrons are held loosely and move freely.

The force of gravity on the moon is only 16.6% the force of gravity on Earth. For each item listed in the table below, fill in what its weight would be on the moon?
==> Take an Earth weight. Don't forget the unit.
==> Multiply it by 0.166 .
==> The product is its Moon weight. Don't forget the unit.
Example:
If I weigh 1,000 lbs on Earth.
Multiply 1,000 lbs by 0.166 .
I weigh 166 lbs on the Moon
The complete table is as follows -
ITEM W(E) W(M)
Apple 150 g 25 g
Hammer 1.5 lbs 0.25 lbs
Person 180 lbs 30 lbs
Blue whale 200 tons 33.3 tons
We have the force of gravity on the moon is only 16.6% the force of gravity on Earth.
We have to fill the table given in the question.
Define Gravity in Physics.In physics, gravity is a fundamental interaction which causes mutual attraction between all things with mass or energy. The gravitational force between two bodies of mass 'm' and 'M' separated by a distance 'r' apart is given by -
[tex]$F = \frac{GMm}{r^{2} }[/tex]
According to the question, we have -
Force of gravity on the moon is only 16.6% the force of gravity on Earth.
This means that for an object of mass 'm' -
F(M) = 16.6% of F(E)
This means that a person would weigh six times less on the moon than they do on Earth -
W(moon) = [tex]\frac{1}{6}[/tex] W(earth)
Let's complete the table -
ITEM W(E) W(M)
Apple 150 g 1/6 x 150 = 25 g
Hammer 1.5 lbs 1/6 x 1.5 = 0.25 lbs
Person 180 lbs 1/6 x 180 = 30 lbs
Blue whale 200 tons 1/6 x 200 = 33.3 tons

A soccer ball is kicked horizontally. What is its average speed if its displacement is 21.0 m
after 2.00 s?
Answer:
Below
Explanation:
You can use this formula to find the average speed/velocity
speed = displacement / change in time
Plugging our values in....
speed = 21.0 m / 2.00 s
= 10.5 m/s
Hope this helps! Best of luck <3
The average speed of a soccer ball is 10.5 m/s.
What is speed?Speed is defined as the ratio of the distance moved by the object at a particular time. The unit of speed is measured in the meter per second, miles per hour, etc. The speed of an object is a scalar quantity and does not require any direction to represent it. It only requires magnitude to represent it.
Average velocity is defined as the sum of all the distances traveled by an object to the time taken by the object to cover the total distance.
Given that a soccer ball is kicked horizontally. its average speed if its displacement is 21.0 m after 2.00 seconds will be calculated as below:-
Speed = displacement / change in time
Speed = 21.0 m / 2.00 s
Speed = 10.5 m/s
Therefore, the average speed of a soccer ball is 10.5 m/s.
