A constant pressure is applied to both cylinders Write the balanced chemical equation for the reaction between nitrogen oxygen. Include physical states.

Answers

Answer 1

Answer:

2N₂(g) + 2O₂(g) ----> 2NO(g)

Explanation:

Gaseous nitrogen and gaseous oxygen reacts in a molar volume ratio of 1 : 1 to produce nitrogen (ii) oxide.

In the reaction, two molecules of nitrogen gas combines with two molecules of oxygen gas in the cylinder to form two molecules of nitrogen (ii) oxide. The equation of the reaction is given below:

2N₂(g) + 2O₂(g) ----> 2NO(g)

Nitrogen (ii) oxide is formed naturally during lightning bolts. The heat released the lightning flashes causes the nitrogen and oxygen in air to combine to form nitrogen (ii) oxide. The nitrogen (ii) oxide formed however, quickly reacts with more oxygen to form nitrogen(ii) oxide.

Nitrogen (ii) oxide is a colorless, poisonous gas. It is slightly denser than air and almost insoluble in water. it is also neutral to litmus.

The Gas-phase Reaction Between Nitrogen And Oxygen Was Carried Out In A Device Designed To Maintain Constant
Answer 2

The balanced chemical equation for the reaction between nitrogen and oxygen is:

2N₂(g) + 2O₂(g) —> 4NO(g)

The equation between nitrogen and oxygen can be written as follow:

N₂(g) + O₂(g) —> NO(g)

The above equation can be balance as illustrated below:

There are 2 atoms of O on the left side and 1 atom on the right side. It can be balance by writing 2 before NO as shown below:

N₂(g) + O₂(g) —> 2NO(g)

Multiply the equation by 2, we have:

2N₂(g) + 2O₂(g) —> 4NO(g)

The equation is balanced!

what are the kinetic energy​

Answers

Answer:

n physics, the kinetic energy (KE) of an object is the energy that it possesses due to its motion.[1] It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

In classical mechanics, the kinetic energy of a non-rotating object of mass m traveling at a speed v is {\displaystyle {\begin{smallmatrix}{\frac {1}{2}}mv^{2}\end{smallmatrix}}}{\begin{smallmatrix}{\frac {1}{2}}mv^{2}\end{smallmatrix}}. In relativistic mechanics, this is a good approximation only when v is much less than the speed of light.

The standard unit of kinetic energy is the joule, while the imperial unit of kinetic energy is the foot-pound.

The position of the convex mirror is such that a real image of distant object is formed on the plane of a hole drilled through the concave mirror at its pole. Calculate 'R' of convex mirror and height of the real image if distant object forms 0.5 degree angle at the pole of the concave mirror.​

Answers

Answer:

Calculate 'R' of convex mirror and height of the real image

the radius of the convex mirror is 48cm

Explanation:

Distance between convex and concave mirror is =60cm

Radius of the concave mirror (R) = 200cm

For the concave mirror, u = ∞

V = {R}/{2}=100cm

The object for the convex mirror and the final image is on the pole of the concave mirror, and distance between convex and concave mirror is 60cm

u_1=60-100 =-40cm

Object will be behind the convex mirror

1/f=1/40+1/60  

f=24cms

the radius of the convex mirror is 48cm

Answer:

Explanation:

We can solve this problem using the principle of conservation of energy.

Starting point. For higher up the ramp

          Em₀ = U = m g h

where h is the height of the ramp h = 3.00 m

Final point. For low

          Em_{f} = K = ½ m v²

as there is no friction the mechanical energy is conserved

          Em₀ = [tex]Em_{f}[/tex]

          m g h = ½ m v²

          v = √ (2g h)

let's calculate

         v = √(2 9.8 3.00)

         v = 7.668 m / s

why didnt people in marie curies time realize radioactivity could be harmfull?​

Answers

Answer:Health

Throughout her work with radium, Marie was unaware of the effects of radioactivity exposure on the body. In her lab, she would keep tubes of radium in her pocket. [3] She began to suspect that radium negatively impacted health when one of her fellow researchers died of a blood disease, and then a few years later her personal assistant died of a blood disease. Even though she suspected that radium exposure was bad for her health, she did very little to monitor her own blood. In 1932, she broke her wrist and the break took much longer to heal than it should have. She then began to notice that her vision was deteriorating and radiation burns on her fingers were becoming more and more painful. Some days she felt too ill to even go to the lab, and finally on July 4, 1934, Marie died from aplastic anemia. [1]

Radium Exposure Treatments

Marie suspected that her health was being negatively impacted by radium exposure, but did nothing about it, most likely because there weren't any effective treatments for radium poisoning yet. At the time, scientists knew that radium was metabolized like calcium. In an attempt to remove it from the system, they manipulated calcium intake. [4] This caused little to no improvements, so parathyroid hormone was added to the treatment. Again, there was some reduction of radium, but not a significant amount. It wasn't until after Marie's death that they realized once radium is in the bones, it is extremely difficult to extract. The lack of therapies for radium exposure may explain why Marie just ignored her symptoms, because she was fully aware of her fate. [4]

Answers

The applied force is parallel to the ground, so the net vertical force on the sled is 0. By Newton's second law, this means the normal force and weight of the sled cancel out:

n - w = 0

NEED HELP LIKE RIGHT NOW PLz

Answers

Answer:

f = 485.62 N

Explanation:

Since, the bag is moving with some acceleration. Hence, the unbalanced force will be given as:

Unbalanced Force = Horizontal Component Applied Force - Frictional Force

Unbalanced Force = Fx - f

But, from Newtons Second Law of Motion:

Unbalanced Force = ma

comparing the equations:

ma = Fx - f

f = F Cos θ - ma

where,

f = frictional force  = ?

F = Applied force  = 593 N

m = mass of person = 49 kg

a = acceleration = 0.57 m/s²

θ = Angle with horizontal = 30°

Therefore,

f = (593 N)(Cos 30°) - (49 kg)(0.57 m/s²)

f = 513.55 N - 27.93 N

f = 485.62 N

Rubidium forms the positive ion Rb+. Does this ion have more or fewer electrons than the neutral atom?

Answers

Answer:

The ion has fewer electrons

Explanation:

As Rubidium forms a positive ion Rb⁺ the number of electrons becomes fewer for the atom.

A positive charge on an ion indicates that the number of protons for the atom is greater than the number of electrons. This leaves a net positive charge on the atom.For a negatively charged ion, the number of electrons is more than the number of protons because they have gained additional electrons. In a neutral atom, the number of protons and electrons are the same.

Rubidium forms the positive ion (Rb+) because it has fewer electrons than the neutral atom.

HOW DOES AN ATOM BECOME POSITIVELY CHARGED:

An atom is the smallest indivisible particle of an element. It consists of three subatomic particles namely: proton, electron and neutron.

Proton is the positively charged component (+) while electron is the negatively charged component (-). The proton and electron number is equal in a neutral atom.

An atom becomes positively charged when it loses electrons. The number of protons becomes more in a positively charged atom. For example, Rubidium forms the positive ion (Rb+) because it has fewer electrons than the neutral atom.

Answers

Answer:

A

Explanation:

Hubble’s law states that galaxies that are farther away have a greater red shift, so the speed at which a galaxy is moving away is proportional to its distance from the Earth. Red shift is a phenomenon due to Doppler shifting, so the shift of light from a galaxy to the red end of the spectrum indicates that the galaxy and the observer are moving farther away from one another. Doppler shifting also is found in the Energy and Waves section of this course.

You are piloting a helicopter which is rising vertically at a uniform velocity of 14.70 m/s. When you reach 196.00 m, you see Barney (Uh-oh). A large object is projected with a horizontal velocity of 8.50 m/s from the rising helicopter. When does the ball reach Barney's head if he is standing in a hole with his head at ground level?

Answers

Answer:

The ball reaches Barney  head in  [tex]t = 8 \ s[/tex]

Explanation:

From the question we are told that

 The rise velocity is  [tex]v = 14.70 \ m/s[/tex]

  The height considered is [tex]h = 196 \ m[/tex]

   The horizontal velocity of the large object is  [tex]v_h = 8.50 \ m/s[/tex]

   

Generally from kinematic equation  

   [tex]s = ut + \frac{1}{2} gt^2[/tex]

Here s is the distance of the object from Barney head ,

        u is the velocity of the object along the vertical axis which is equal but opposite to the velocity of the helicopter

So  

     [tex]u = -14.7 m/s[/tex]

So

    [tex]196 = -14.7 t + \frac{1}{2} * 9.8 * t^2[/tex]

=  [tex]4.9 t^2 - 14.7t - 196 = 0[/tex]

Solving the above equation using quadratic formula  

    The value of  t obtained is  [tex]t = 8 \ s[/tex]

Pls solve to the fullest do not copy question and give very detail of how to do it pls and thank you

Answers

Answer:

Speed = 8.79m/s

Explanation:

Given the following data;

Height = 4m

Horizontal distance = 8m

To find the time, we would use the second equation of motion

S = ut + ½at²

We know that acceleration due to gravity is equal to 9.8m/s²

Initial velocity, u = 0

Substituting into the equation, we have;

4 = 0(t) + ½*9.8*t²

4 = 0 + 4.9*t²

4 = 4.9t²

t² = 4/4.9

t² = 0.82

Taking the square root of both sides, we have;

t = 0.91 secs

To find the speed;

Speed = horizontal distance/time

Speed = 8/0.91

Speed = 8.79m/s

Therefore, the pelican's speed is 8.79 meters per seconds.

What is the acceleration due to gravity?

Acceleration due to gravity is the acceleration that an object experiences due to the gravitational force exerted by a massive body, such as Earth. The acceleration due to gravity on Earth is approximately 9.8 meters per second squared (m/s^2) and is denoted by the symbol "g".

The acceleration due to gravity is a vector quantity, which means that it has both magnitude and direction. The direction of the acceleration due to gravity is always downwards, towards the center of the massive body.

The acceleration due to gravity is a constant value near the surface of the Earth, but it can vary slightly depending on altitude, latitude, and the composition of the Earth's interior. For example, at higher altitudes, the acceleration due to gravity decreases slightly, while at the equator, it is slightly greater than at the poles due to Earth's rotation.

The acceleration due to gravity plays an important role in many physical phenomena, including free fall, projectile motion, and the behavior of fluids in containers.

Here in the Question,

The weight of a 75 kg person on Earth can be calculated using the formula:

weight = mass x acceleration due to gravity

Substituting the given values, we get:

weight = 75 kg x 9.8 m/s^2

weight = 735 N

Therefore, the weight of a 75 kg person on Earth is 735 N, which is option D.
