Explain how the temperature of a substance is related to the kinetic of it molecules.

Answers

Answer: this is the explanation

Explanation:

the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles

More kinetic energy means more collision of particles,therefore, as particles collide more the temperature rises.

If velocity is positive, which would most likely yield a negative acceleration?
O O OO
A final velocity that is faster than an initial velocity.
A time that is less than a half hour.
An initial velocity that is faster than a final velocity.
A time that is greater than a half hour.

Answers

Answer:

An initial velocity that is faster than a final velocity

Explanation:

The relationship between velocity and acceleration is given as follow;

Acceleration = Change in velocity / Time

Change in Velocity = Final Velocity - Initial Velocity

From the formular, time is not able to affect the sign of the acceleration.

A negative acceleration is also referred to as deceleration and this occurs when there is a drop in velocity.

A drop in velocity occurs when the initial velocity is faster than the final velocity.

Suppose Earth’s gravitational force were decreased by half. How would this change affect a game of basketball? Think about the motion of the players and the ball.

Answers

Answer:

Due to the decrease in the gravitational force, it will take longer time for ball to reach the ground while dribbling. Moreover, the hang time of players will also be longer. This means that the players will stay on air longer and will be able to jump higher.

Which type of mass movement is the most destructive?

creep
erosion
landslide
slump

Answers

Answer:

•landslide

Explanation:

Landslides are exceptionally destructive. Homes may be destroyed as hillsides collapse. Landslides can even bury entire villages. Landslides may create lakes when the rocky material dams a stream.

The type of mass movement is the most destructive landslide.

What is landslide?

Several forms of mass wasting that may include a wide range of ground movements, such as shallow or deep-seated slope failures, rockfalls, mudflows, and debris flows are known as landslips or landslide.

Sometimes more than one type of movement occurs within a single landslide, and analysis of each requires detailed interpretation of landforms and geological sections.

Landslides are exceptionally destructive. Homes may be destroyed as hillsides collapse. Landslides can even bury entire villages. Landslides may create lakes when the rocky material dams a stream.

There are measures that can be taken to reduce the potential for a landslide to occur, such as steep slope reinforcement, installing structures using pile foundations and checking surface drainage. The easiest way to prevent a landslide is to avoid building in areas that are – or might become – prone to landslides.

Given options are-

creep

erosion

landslide

slump

Therefore, The type of mass movement is the most destructive landslide.

The empirical formula of a compound is determined to be N2O5. If the molar mass of the compound is 108 g/mol, determine the molecular formula of the compound.

Answers

Answer:

N2O5

Explanation:

Empirical formular is the simplest formular of a compound and shows the atoms present in simple rations.

Molecular formular on the other hand shows the exact number of atoms of element present in a compound.

To obtain molecular formular from empirical formular;

(Empirical formular)n = Molar mass

where n is a simple integer.

(N2O5)n = 108 g/mol

Molar mass of N2O5 = 108 g/mol

(108) n = 108

n = 108 / 108 = 1

Molecular formular = (Empirical formular)n

Molecular formular = (N2O5)*1 = N2O5

In this question, the empirical formular is the same as the molecular formular

A box that is 35 inches X 35 centimeters X 0.065 yards will have a volume of
centimeters.

Answers

Answer:

V = 18,493.5114 cm³

Explanation:

Dimensions are;

L = 35 inches

W = 35 cm

H = 0.065 yards

Now, volume is given by;

V = LWH

But our dimensions need to all be in the same unit, so let's convert to cm.

L = 35 inches = 35 × 2.54 cm = 88.9 cm

H = 0.065 yards = 0.065 × 91.44 = 5.9436 cm

Thus;

V = 88.9 × 35 × 5.9436

V = 18,493.5114 cm³

How does the concept of conservation of mass apply to chemical reactions?

Answers

Answer:

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

If you add more molecules but do not change the temperature or the pressure, what will happen to the system?
the molecules will move faster
O the volume will decrease
the volume will increase
the molecules will move slower

Answers

Answer:

the volume will increase

Explanation:

The kinetic energy of gas molecules depend upon the temperature . If temperature is increased , the molecules will move faster . When temperature is decreased , they move slower .

Hence when more molecules are added to a gas without changing its temperature , the velocity of gas molecules will remain unchanged .

Since pressure  is also constant , it is volume which will be increased .

It can be explained from universal gas formula as follows

PV = nRT

P , R and T is constant ,

V ∝ n

Volume is proportional to n which depends upon number of molecules .

So volume will increase if number of molecules increases .

if you had a block square that weighed 5.00 grams what would be the length of each side

Answers

Answer:

[tex]l = 0.793[/tex] cm

Explanation:

Let us assume the density of block square [tex]10[/tex] g/cm³

As we know

Volume = [tex]\frac{Mass}{Density}[/tex]

Thus Volume of this block is equal to [tex]\frac{5}{10} = 0.5[/tex]

As we know volume of square block of side of length "l" is equal to [tex]l^3[/tex]

[tex]l^3 = 0.5[/tex]

[tex]l = 0.793[/tex] cm

which diagram would it be?

Answers

Answer:

2CH4 ------> 3H2 + C2H2

Explanation:

The law of conservation of mass states that atoms can neither be created nor destroyed in a chemical reaction.

The implication of this law is that the number of atoms of each element on the reactant side must be equal to the number of atoms of each element on the product side.

This law is only obeyed by the reaction, 2CH4 ------> 3H2 + C2H2

There were eight atoms of H on the left hand side as well as the right and side of the reaction equation. There were two atoms of C on both the left and right hand sides of the reaction equation respectively. Hence, the law was obeyed here.
