Answer:

noble gases is those group of elements that DO NOT form ions and are found as monatomic atoms in nature .

The only group of elements that DO NOT form ions and are found as monatomic atoms in nature are the: noble gases.

The noble gases are a group of chemical elements with comparable qualities; under normal conditions, they are all odourless, colourless, monatomic gases with very minimal chemical reactivity. Historically, they were also known as inert gases and aerogens. Helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radioactive radon are the six naturally occurring noble gases (Rn).

Oganesson (Og) is a highly radioactive element created synthetically. Although the IUPAC has included oganesson since "group 18" and "noble gas" have been used interchangeably, oganesson may not be appreciably chemically noble and is projected to deviate from the norm and be reactive due to relativistic effects. Its chemistry has not yet been studied due to the single known isotope's relatively brief 0.7 ms half-life.

Answer:

3072J

Explanation:

At all points through her slide, it is important to reiterate that energy is always conserved.

Kinetic energy is the energy due to the motion of a body.

Potential energy is the energy due to the position of a body.

Based on the law of conservation of energy, energy is neither created nor destroyed but simply transformed from one form to another.

 So;

At all points:

           Total energy  = Potential energy + Kinetic energy

Since the initial energy  = 5000J which is the potential energy

This is the total energy within the system as the kinetic energy at this point is 0;

 After a few seconds, the potential energy is 1928J;

  Kinetic energy  = Total energy  - potential energy  = 5000J  - 1928J

  Kinetic energy  = 3072J

Answer:

15 m/s^2 The first thing to calculate is the difference between the final and initial velocities. So 180 m/s - 120 m/s = 60 m/s So the plane changed velocity by a total of 60 m/s. Now divide that change in velocity by the amount of time taken to cause that change in velocity, giving 60 m/s / 4.0 s = 15.0 m/s^2 Since you only have 2 significaant figures, round the result to 2 significant figures giving 15 m/s^2

Answer:

The resistance is 0.617Ω.

Explanation:

Given that the formulas are V = I × R and P = I × V so when you substitute the V formula into P formula, you will get P = I² × R. Using this formula, you can find the resistance :

P = I² × R

50 = 9² × R

50 = 81 R

50 ÷ 81 = R

R = 0.617Ω (3sf)

Answer:

Explanation:

Given parameters:

Force applied on the car  = 1000N

Unknown:

Work done  = ?

Solution:

The work done by a body is the force applied to move it through a particular distance.

So;

    Work done  = Force x distance

Therefore;

    Work done  = 1000 x 75  = 75000J

Answer:

51.85m/s

Explanation:

Given parameters:

Mass of ball  = 0.0459kg

Force  = 2380N

Time taken  = 0.001s

Unknown:

Speed of the ball afterwards  = ?

Solution:

To solve this problem, we use Newton's second law of motion:

   F = m x [tex]\frac{v - u}{t}[/tex]  

F is the force

m is the mass

v is the final velocity

u is the initial velocity

t is the time taken

        2380  = 0.0459 x [tex]\frac{v- 0}{0.001}[/tex]  

        0.0459v  = 2.38

                   v = 51.85m/s

Answer:

2.38

Explanation:

F = dp/dt  --> dp = F*dt ---> p = F*t if F is constant over time so

p = 2380N* 0.001 s = 2.38 kg-m/s

How much power does the Ox exerts  = ?

Solution:

Power is the rate at which work is being done

  Power  = [tex]\frac{Work done }{time}[/tex]  

 Power exerted by ox  = [tex]\frac{120}{15}[/tex]   = 8W

The chemical process which requires energy is breaking bond in KOH and HBr. Hence, option C is correct.

The capacity to perform work is known as energy in physics. Potential, kinematic, thermodynamic, electromagnetic, chemical, nuclear, and other types are all possible.

As energy is transferred through one body to another, there is also heat and work. As a result, heat transfer may result in thermal energy, whereas labor done may result in mechanical power.

As per the given reaction in the question,

KOH + HBr - KBr + H20

Here, in this reaction the chemical process which requires the energy is at the time of breaking of bonds in KOH and HBr at that time the energy is required.

Therefore, it is concluded that breaking bonds in KOH and HBr i.e., option C is correct.

Explanation:

4.02 m/sec² is the acceleration of a 10 kg block that experiences a 50 N applied force as it slides across a horizontal surface.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

force = 50 N - frictional force = ma

50 - 9.8 = ma

a = 40.2/10

a = 4.02 m/sec²

4.02 m/sec² is the acceleration of a 10 kg block that experiences a 50 N applied force as it slides across a horizontal surface.

Answer:

500.3 Bq

Explanation:

From the formula;

0.693/t1/2 = 2.303/t log (Ao/A)

Where;

t1/12 = half life = 5 years

Ao = initial activity = 2000 Bq

0.693/5 = 2.303/10 log (2000/A)

0.1386= 0.2303  log (2000/A)

0.1386/0.2303 =  log (2000/A)

0.6018 = log (2000/A)

(2000/A) = Antilog (0.6018)

(2000/A) = 3.9976

A = 2000/3.9976

A = 500.3 Bq

Answer: ethanol which will dissolve in both water (a polar solvent) and gasoline (a non-polar solvent)

Explanation:

According to the concept of solubility, ethanol is a molecule which is soluble in both polar and non-polar solvents.

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

2. The kinetic energy of the tennis ball is 0.725 J

Explanation:

The following data were obtained from the question:

Mass (m) = 0.058 kg

Velocity (v) = 5.0 m/s

Kinetic energy (KE) =.?

1. Defining an expression which relates kinetic energy, mass and speed of an object.

Kinetic energy is simply defined as the energy possess by an object in motion. Mathematically, kinetic energy can be represented as:

KE = ½mv²

Where

KE => is the kinetic energy.

m => is the mass of the object.

v => is the velocity of the object.

2. Determination of the kinetic energy of the tennis ball.

Mass (m) = 0.058 kg

Velocity (v) = 5.0 m/s

Kinetic energy (KE) =.?

KE = ½mv²

KE = ½ × 0.058 × 5²

KE = 0.029 × 25

KE = 0.725 J

Thus, the kinetic energy of the tennis ball is 0.725 J.
