Answer:

it could depend on the environment of the area, how the sun rays are parting through particles in the air, or it jus might be the amount of heat radiation is coming down cause it could be a chilly sunny day or a hot sunny day

The speed of the car = 22.25 m/s

Given

A distance of 22.75 km

Time = 17.04 minutes

Required

The speed (in m/s)

Solution

Speed is the ratio of distance per time

Can be formulated :

v = d/t  

v= speed, m/s

d=distance=m

t=time,s

Input the value :

[tex]\tt v=\dfrac{22.75~km}{17.04~minutes}\times \dfrac{1000~m}{1~km}\times \dfrac{1~minute}{60~second}\\\\v=\boxed{\bold{22.25~m/s}}[/tex]

Converting Between Moles and Liters of a Gas at STP. To convert between moles and the volume of a gas at STP, we will use the factor label method discussed in the first unit. This conversions relies on the fact that a mole of gas at STP has a volume of 22.4 L.

Explanation:

One molecule of carbon dioxide at STP has a volume of 22.4 liters . Thus number of molecules of carbon dioxide in 12.2 L is 3.27 × 10²³ molecules.

A molecule is formed by the combination of same or different kinds of atoms. A number molecules together form a compound. Water, carbon dioxide etc. are compounds.

One mole of a molecule contains 6.022 × 10²³ number of atoms. Similarly, one mole of a compound contains, 6.022 × 10²³ number of molecules.This number is called Avogadro number.

At standard temperature and pressure (STP) that is at 298 K and 1 atm pressure, one mole of any substance carry 22.4 L. Thus number moles of 12.2 L of carbon dioxide is 12.2 / 22.4 = 0.54 moles.

Number of molecules = 0.54 moles × 6.022 × 10²³

                                     =  3.27 × 10²³

Hence, number of molecules of carbon dioxide in 12.2 L is 3.27 × 10²³ molecules.

Answer:through the conduction from magma to water and rocks

Explanation:

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:

2578.608 centimeters in 28.2 yards.

Explanation:

There are 91.44 centimeters to a yard. Multiplying 91.44 by the number of yards, we get the number of centimeters per yards.

91.44(28.2) = 2578.608

Answer:

Coulombs equation involves distance and the distance from one radius to the next allows us to predict certain characteristics such as pull and attraction. For example, you would expect, a higher charge on the ion and a higher dipole moment causes a larger force. This is due to the magnitude which is the distance between these two and effectively that is how Columbus law comes into play.

Coulomb's law states that the force of repulsion or attraction among both two charged bodies is directly proportional to the product of their charges as well as inversely proportional to the square of the length between them.

An electric force is created when two charged particles collide. The forces will be greater if you have larger charges.

Coulomb's Law can be understood by combining these two ideas and the fact that charges can attract and repel each other. It is a formula for calculating the electrical forces between two objects.

Coulomb's equation involves distance, and the distance between two radiuses allows us to predict certain characteristics such as pull and attraction.

As you might expect, a higher charge on the ion and a higher dipole moment result in a greater force. This is due to the magnitude of the distance between these two, and this is where Columbus law comes into play.

Thus, this way, Coulomb's law can help you understand why some interparticle forces are stronger than others.

Balanced equation

Solution

There are 3 ways to express a chemical equation:

Skeleton equation for reaction above :

LiI(aq) + AgNO₃(aq) ⇒ AgI(s) + LiNO₃(aq)

If we look at this reaction, all the cations and anions have a charge of 1 (+1 or -1) so the balanced reaction between the skeleton equation and the balanced equation is the same

The study of chemicals is called chemistry.

Pseudoscience

Explanation:

Predicting the future based solely on the position of the planets is an example of pseudoscience.

Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.

Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.

Any other statement or belief that is not based on these procedures is said to be pseudoscientific.
