What type of plate boundary (divergent, convergent, or transform) is typically
associated with sliding or shear forces?
convergent
transform
divergent

Answers

Answer:

transform

Explanation:

The type of plate boundary associated with sliding or shear forces is a transform plate boundary.

Two or more plates slides laterally past one another due to presence of shear forces acting on them.

In this margin, there is often an occurrence of earthquake. For a divergent margin, plates move apart and away from one another. This leads to the creation or formation of new crusts. At a convergent margin, two plates collides, a plate can subduct under another or both can become uplifted. Tectonic margins are known for their various activities.

Answer:

convergent

Dinitrogen pentoxide is used in the preparation of explosives. If 7.93 mol of
dinitrogen pentoxide undergoes simple decomposition, what volume of Oz(9) is
produced at 48.0 °C and 125 kPa?

Answers

The volume of O₂ produced: 84.6 L

Further explanation

Given

7.93 mol of  dinitrogen pentoxide

T = 48 + 273 = 321 K

P = 125 kPa = 1,23365 atm

Required

Volume of O₂

Solution

Decomposition reaction of dinitrogen pentoxide

2N₂O₅(g)→4NO₂(g)+O₂ (g)

From the equation, mol ratio N₂O₅ : O₂ = 2 : 1, so mol O₂ :

= 0.5 x mol N₂O₅

= 0.5 x 7.93

= 3.965 moles

The volume of O₂ :

[tex]\tt V=\dfrac{nRT}{P}\\\\V=\dfrac{3.965\times 0.082\times 321}{1.23365}\\\\V=84.6~L[/tex]

Where does the waste material in the body come from
and why does the body need to get rid of these waste
materials?

Answers

Answer:

The cells of the body produce waste materials. The body needs to get rid of these waste materials because they can make us sick. Getting rid of this waste keeps us healthy.

Explanation:

____________________________________________________________

               The Answer I Put On Mine:

____________________________________________________________

The cells inside of your and my body alike produce these waste materials. We need to get rid of them because if we don't, we could get sick! Or possibly cause something worse...

____________________________________________________________

                                 Why?

____________________________________________________________

Well, the answer kind-of explains all I would want to say! Feel free to copy and paste this on your assignment, but do NOT use the sample answer like the other person who answered this did. (The sample answer you should NOT use: "The cells of the body produce waste materials. The body needs to get rid of these waste materials because they can make us sick. Getting rid of this waste keeps us healthy.") It could make your teachers or parents suspicious of your work! Anyways, have a good day! ❥

An alcohol thermometer makes use of alcohol's changing in order to measure temperature. As the temperature goes up.
the alcohol contained in the thermometer increases in volume, filling more of the thermometer's tube.
A. state
B. mass
C. density
D. chemical composition

Answers

The question is incomplete, the complete question is;

An alcohol thermometer makes use of alcohol's changing _______ in order to measure temperature. As the temperature goes up, the alcohol contained in the thermometer increases in volume, filling more of the thermometer's tube.

A.

mass

B.

state

C.

chemical composition

D.

density

Answer:

D.

density

Explanation:

Every kind of thermometer makes use of a change in a particular physical property of a substance as a measure of temperature. It must be a property that changes with temperature.

Density of a substance changes with temperature. Even though the mass of alcohol in glass remains constant, but its volume increases or decreases with change in temperature leading to a change in volume and consequently a change in density of the alcohol in glass. This change is used as a measure of the change in temperature.

how many atoms are in 0.340 moles of sodium

Answers

The number of atoms that are in 0.340 moles of sodium is 2.047×10²³ atoms.

What is Avogadro's number?

Avogadro's number is equal to 6.022×10²³ which gives idea about the number of atoms present in one mole of any substance.

i.e. In 1 mole = 6.022×10²³ atoms

Given moles of sodium = 0.34 mol

Number of atoms of sodium in given moles will be calculated as:

No. of Na atoms = 0.34mol × 6.022×10²³ atoms/mol = 2.047×10²³ atoms

Hence required number of atoms are 2.047×10²³ atoms.

Please select the best answer from the choices provided

D

Answers

Answer:

d making models.

Explanation:

When scientists create a representation of a complex process, they are inferring that they are making models.

A model is an abstraction of the real world or a complex process. Models are very useful in developing solutions to processes that are not easily simplified.

The models allow a part of a body to be simply studied. Through this simple abstraction, extrapolations to other parts of the system can be deduced. This can give very useful insights into the other parts of the system. The heterogeneity of complex processes is a huge limitation to understanding them. A homogenous part can be modelled and used to understand the system.

Answer:

D. making models.

Explanation:

Why are noble gases, like helium and krypton, unlikely to form a bond?
A. They do not have valence electrons and therefore cannot form bonds by sharing or trading
electrons.
B. They always have an equal number of protons and electrons.
C. They have full valence
orbitals and already have low energy.
D. They are nonmetals and gases and therefore their ionization energy is too high to form a bond.

Answers

Answer:

The valence electrons are the only parts of an atom that make chemical bonds. Noble gases don't form chemical bonds because they have a full outer shell (8 electrons).
