Lesson Question: What is the effect of temperature on the solubility of a solid in a liquid?

Explanation:

Answer:

The Kelvin Scale has the highest value fir the boiling point of water. The Kelvin degree is the same size as the Celsius degree; hence the two reference temperatures for Celsius, the freezing point of water (0°C), and the boiling point of water (100°C), correspond to 273.15°K and 373.15°K, respectively.

Answer:

The Answer is Kelvin

This means that the atom you're looking for has an atomic mass of 23, which corresponds to the atomic mass of Vanadium, a transition metal located in the fourth row, group 5 of the periodic table.

Vanadium's noble gas shorthand notation is

Answer:

number of molecules and the number of moles

Explanation:

Its always same for molcols

The relationship between number of molecules and the number of moles  is more consistent as the moles and molecules are related by Avogadro's number.

Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.

It has a SI unit of reciprocal mole whose numeric value is expressed in reciprocal mole which is a dimensionless number and is called as Avogadro's constant.It relates the volume of a substance with it's average volume occupied by one of it's particles .

According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.

Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number

Answer:

One plate is going underneath the other plate and sinking into soft rock below.

Explanation:

Tectonic plates will move each other to form rocks and mineral layers. The correct diagram which showing the result of two tectonic plates to each is diagram C.  One plate is going underneath the other plate and sinking into the soft rock below.

Earth's  lithosphere composed of tectonic plates of different sizes and shapes. These plates move away or each other results in the formation of soft rocks and mineral layers.

The magma inside the mantle of earth crust become hot fluid by convection and it flows out. This flow of magma creates slight movement in tectonic plates finally they move in different directions.

The rocks in earth crust will undergoes weathering and results in sand formation. The boundaries of the tectonic plate will be different in different regions and characteristics of that region depends on the type of boundary such as presence of islands volcanoes etc.

When two tectonic plates moves each other one  plate is going underneath the other plate and sinking into the soft rock below. Hence, option C correct.

Diagram A: Two plates are hitting each other, and the plates are breaking into pieces, creating sand.

Diagram B: Two plates are pushing against each other, causing the edges to bend upward.

Diagram C: One plate is going underneath the other plate and sinking into the soft rock below.

Diagram D: One plate is going underneath the other plate and sinking into the ocean below

Explanation:

They have a directly proportional relationship.

i.e.

when one of them varies in magnitude, the others will also vary directly.

Quantities expressed as products of each other are always inversely proportional & those expressed as quotients are directly proportional with each other.

KE = 1/2mv^2

Thus, we know that m & v in KE are inversely related.

Inverse proportionality - when m increases, v decreases. & vice versa.

Direct proportionality - when v increases KE also increases

If Temperature increases then the probability of atoms to randomly collide with each other increases rapidly.

the rapidity of these atoms result from the increase in speed(v). since v & KE have a direct r/n ship, KE also increases. as a result the atoms get a relatively high freedom of movement compared to that of those in solids.

Answer: Option B; It traps light energy and converts it into chemical energy.

Answer:

if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.

Photosyntheis is a biochemical reaction that combines chemicals with biological species to produce energy. Atoms of hydrogen bond with carbon to form glucose.

Carbon dioxide and hydrogen are the reactants that are used from the environment by the plants to make energy. Glucose and oxygen are the products.

The hydrogen atoms from the environment are absorbed by the plants and are combined with the carbon dioxide to yield glucose or sugar molecules for energy.

Therefore, option B. hydrogen and carbon dioxide react to produce glucose.

Answer:

Under high temperatures and low pressure, gases behave the most ideal.

Explanation:

Low pressure reduces the effect of the finite size of real particles by increasing the volume around each particle, and a high temperature gives enough kinetic energy to the particles to better overcome the attractions that exist between real particles. (Prevents sticking.)

In summary, real gases behave more like ideal gases when they are far away from a phase boundary, (condensation or freezing).

Explanation:

The equilibrium constant of the second reaction is 0.155.

The equilibrium constant is a numerical value that shows the extent to which reactants are converted into products at a given temperature.

Now, we have the reaction; 3Z + Q ⇄ 2 X  and  4 X ⇄ 6 Z + 2 Q.

In the first reaction;

K =[ X]^2/[Z]^3 Q

In the second reaction;

[Z]^6 [Q]^2/[X]^4

Let [ X]^2 = A

[Z]^3 Q = B

Then the second reaction can be;

K = (B)^2/(A)^2 = (B/A)^2

The equilibrium constant of the second reaction therefore is; (1/2.54)^2

K = 0.155

Answer:

Does water move in or out of a hypotonic solution?

In a hypertonic solution, the net movement of water will be out of the body and into the solution. ... In hypotonic solutions, there is a net movement of water from the solution into the body. A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis.

Explanation:

If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

The concentration of NO2 is 0.054 M and that of N2O4 is 0.003 M.

The equilibrium constant shows the extent to which reactants are converted into products.

We have the reaction;  N2O4⇌2NO2 and Kp = 4.5. Setting up the ICE table, we have;

       N2O4       ⇌     2NO2

I       0. 0550               0

C       -x                        +x

E    0. 0550 - x            x

Given that;

Kp = [NO2]^2/[N2O4]

4.5= (x)^2/0. 0550 - x

4.5(0. 0550 - x) = x^2

0.2475 - 4.5x = x^2

x^2 +  4.5x -  0.2475 = 0

x=0.054 M

The concentration of the required NO2 gas at equilibrium is 0.054 M and that of N2O4 is 0.003 M.
