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.

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.

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.

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 .

Answer: this is how it works

Explanation:

The magma bursts through Earth's surface in the form of a volcano. Heat and pressure deep in the Earth makes some rocks change to metamorphic rock. Layers of rock get squashed and packed together and gradually harden to form sedimentary rock. The igneous rock gets broken down by weather, and the cycle begins again.

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

Explanation:

The electrons farthest from the nucleus of the atom​

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.

Answer:

Cation and anion

Explanation:

Positive ion is known as cation and negative ion is known as anion

disolvin rate is The rate at which a solute dissovles depends upon the size of the solute particles. Dissolving is a surface phenomenon since it depends on solvent molecules colliding with the outer surface of the solute.

saturation the degree or extent to which something is dissolved or absorbed compared with the maximum possible, usually expressed as a percentage.

changes in solubility  For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution. A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute.

dilution is the making something weaker in force, content, or value.

Colligative properties of solutions are properties that depend upon the concentration of solute molecules or ions, but not upon the identity of the solute. Colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.

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

Answer:

Seismic waves are produced when suddenly released some sort of energy stored in Earth's crust, usually when suddenly fracture and "slip" masses of rock straining against each other. Earthquakes occur most frequently along geological faults, narrow zones where rock masses shift in relation to each other.

Explanation:

The equation of the reaction is;

H2O2 + N2H4 → N2 + H2O

Upon balancing the reaction, we have;

N2H4 + 2H2O2 → N2 + 4H2O  

a. How many moles of N2 are formed from 0.0250 moles of N2H4?

From the equation of the reaction;

1 mol of N2H4 produces 1 mol of N2

0.0250 mol of N2H4 would produce x mol of N2

1 = 1

0.0250 = x

x = 0.0250 * 1 / 1 = 0.0250 mol

b. How many moles of H2O2 are required if 1.35 moles of H2O is to be produced?

From the equation of the reaction;

2 mol of H2O2 produces 4 mol of H2O

x mol of H2O2 produces 1.35 mol of H2O

2 = 4

x = 1.35

x = 1.35 * 2 / 4 = 0.675 mol

c. How many moles of H2O are formed if 1.87 moles of N2 is produced?

The relationship between H2O produced and N2 is;

For every 1 mol of N2 produced, 4 mol of H2O is produced

1.87 mol of N2 produced, how many moles of H2O is produced?

1 = 4

1.87 = x

x = 1.87 * 4 / 1 = 7.48 mol

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
