Rate of  consumption of  N₂ = - 1.25 x 10⁻⁴

The reaction rate (v) shows the change in the concentration per unit time.  

[tex]\tt rate=\dfrac{concentration(M)}{time(s)}[/tex]

The rate reaction for Haber Bosch :

N₂(g)+3H₂(g)⇒2NH₃(g)

From equation, mol ratio N₂ : NH₃ = 1 : 2, so

the rate of formation of ammonia = 2 x the rate of consumption of nitrogen.

Given

the rate of formation of ammonia gas : 2.5x10⁻⁴ M/s

the rate of consumption of nitrogen :

[tex]\tt \dfrac{2.5\times 10^{-4}}{2}=1.25\times 10^{-4}[/tex]

The sign negative for consumption : -1.25 x 10⁻⁴ M/s

or we can use another way:

Rate of formation of  NH₃  = reaction rate x coefficient of  NH₃

2.5 x 10⁻⁴ = reaction rate x 2

reaction rate = 1.25 x 10⁻⁴

Rate of  consumption of  N₂  = reaction rate x coefficient of N₂

Rate of  consumption of  N₂ =  1.25 x 10⁻⁴ x 1

Rate of  consumption of  N₂ =  1.25 x 10⁻⁴

Answer:

The ratio of atoms in a compound is fixed.

Explanation:

its a

Answer:

The charge of an atom is determined by the ratio of protons to electrons

Explanation:

I hope this helps!!

A relationship showing the charge on an atom can be expressed as  ;

The charge an atom posses depends on the particles/components of the atom which are protons and electrons. The protons are positively charged ions that are present in the nucleus of an atom while electrons are negatively charge ions present in the outer shell of an atom.  

To predict the charge on an atom we will determine the difference between the  number of protons and the number of electrons present in an atom.

Hence we can conclude that the relationship can be expressed as Types of particle are protons and electrons , Charge on atom = ( Number of protons - Number of electrons )

Answer:

PET works by using a scanning device (a machine with a large hole at its center) to detect photons (subatomic particles) emitted by a radionuclide in the organ or tissue being examined.

Newer technology combines PET and CT into one scanner, known as PET/CT. PET/CT shows particular promise in the diagnosis and treatment of lung cancer, evaluating epilepsy, Alzheimer's disease and coronary artery disease.

Answer:

v = 16.49 m/s

Explanation:

Given that,

Length of the string, l = 1.15 m

The ball makes 137 complete turns each minute.

We know that, 1 turn = 6.28 rad

137 turns = 860.79 rad

1 min = 60 s

[tex]\omega=\dfrac{860.79\ rad}{60\ s}\\\\=14.34\ rad/s[/tex]

We need to find the tangential velocity of the ball. It can be given by

[tex]v=r\omega\\\\=1.15\times 14.34\\\\v=16.49\ m/s[/tex]

So, the tangential velocity of the ball is 16.49 m/s.

Gives brown colour gas

Answer:

2.54mole of H₂

Explanation:

The reaction expression is given as:

           2H₂O  →   2H₂  +   O₂

Given;

Number of moles of H₂O  = 2.54moles

Unknown:

Number of moles of H₂ produced  = ?

Solution:

To solve this problem, we use the concept of mole comparison. Now from the reaction expression, we know that;

                  2 mole of H₂O will produce 2 mole of H₂

                 2.54 mole of H₂O will then produce 2.54mole of H₂

A Front

Explanation:

A Front is a boundary between two air masses of different density, moisture, or temperature

Answer:

When sleeping the energy exhibited is Potential energy. When I wake up and I’m preparing for the day I use kinetic energy which is the energy exhibited during motion.

Eating before leaving the house means I used chemical energy for replenishment of nutrients to aid the performance of more activities for the day. The food eaten and the physical activities also give rise to thermal energy which is why we sweat.

Answer: The spectrum would be continuous

Explanation:

Atomic transitions allow us to find that the correct answer to what would happen if there was no quantization is:

          d. the spectrum would be continous

In the models of atoms the correct explanation for the energy was given by Planck, by establishing that the energy of an electron is:  

           E = h ν

Where E is the energy, h the Planck constant and ν the frequency.

Therefore a transition occurs as the jump of an electron from one level to another  

          ΔE = E₂ - E₁

In all atomic models the levels are discrete, so the jumps are also discrete.

If the levels were continuous, the energy difference between the lines disappears and we have a continuous emission spectrum.

Let's review the different answers:

a. False. The lines disappear

b. False. This for if the separation between levels increases, which is the opposite process to the one analyzed.

c. False. The lines disappear

d) True. The spectrum is a continuum without any separation.

In conclusion, using the atomic transitions we find that the correct answer for what would happen if there was no quantization is:

     d. the spectrum would be constnuous

No.

Explanation:

No, Pedro's observations does not suggest that replanting the garden with red flowers caused a change in the ladybird beetle population because the colour of flower has no effect on the change in the population of ladybird beetle, it must be occur due to the dominant genes present in the population of ladybird beetle. This dominant genes is responsible for the presence of more red colour on the ladybird beetles shells.

The industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels from 280 parts per million to about 417 parts per million in the last 151 years. The panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in Earth's temperatures over the past 50-plus years.
