how many moles of ammonia could be obtained from a maximum of 5.0 moles of nitrogen?

Activation energy is best defined as the minimum energy required by the reactant to overcome the barrier potential in a chemical reaction.

Every reaction is taking place within some preferred condition and and without achieving this, the reaction does not proceed. According to kinetic theory of particles. The particles of different elements collide each other and form products.

For the effective collision, the reactant particles have to overcome a barrier potential, for which they have to attain some energy beyond their actual energy.

This energy that the reactants have to attain to overcome the barrier potential of a reaction is called its activation energy. The less the activation energy, more will be the reaction rate.

Increase in temperature and addition of catalysts helps to reduce the activation energy.

The quantity of ice added to the glass was 45.9 g.

To solve this problem, we can use the equation for heat transfer: q = m*C*ΔT, where q is the heat transferred, m is the mass, C is the specific heat capacity, and ΔT is the change in temperature.

First, we need to find the amount of heat lost by the water as it cools from 55°C to 15°C:

q lost = (50.0 g)(4.18 J/g°C)(55°C - 15°C) = 10,520 J

Next, we need to find the amount of heat gained by the ice as it melts and then heats up to 15°C:

q gained = (m ice)(334 J/g) + (m ice)(4.18 J/g°C)(15°C - 0°C)

We know that the specific heat capacity of ice is 2.09 J/g°C, and the heat of fusion for water is 334 J/g.

We can combine these two equations and solve for the mass of ice:

q lost = q gained

10,520 J = (m ice)(334 J/g) + (m ice)(4.18 J/g°C)(15°C - 0°C)

10,520 J = (m ice)(334 J/g + 62.7 J/g)

Answer:

- Water from beaker will move to the tube

Explanation:

Total percentage of water in the beaker;

\( = { \tt{100\% - 5\%}} \\ = { \tt{95\%}}\)

Total percentage of water in dialysis tube;

\({ \tt{ = 100\% - 15\%}} \\ = { \tt{85\%}}\)

So, there is much water concentration in the beaker than the dialysis tubing, this causes a determined percentage of water to diffuse to the tubing, and determined percentage of salt to move from tubing to the beaker.

Percentage of water moving to tubing;

\({ \tt{ = 95\% - 85\%}} \\ = { \tt{10\%}}\)

Percentage of salt moving from tubing to beaker

\({ \tt{ = 15\% - 5\%}} \\ { \tt{ = 10\%}}\)

Rain freezing is a condition of "exothermic" process. The freezing rain emits thermal energy, which is then transmitted to the earth. The earth will receive thermal energy if the rain loses thermal energy. As a result, the ground's temperature rises.

Due to the salt in saltwater, it freezes at a lower temperature than fresh water, approximately 28.4 degrees Fahrenheit (ca. -2 °C). However, because only the water portion of saltwater freezes, very little salt is present in the ice when it is formed. Water may be made from it by melting it down.

The magnitude of the average emf induced in the coil during the 0.34 s is 0.318 V.

The emf induced in a coil is given by Faraday's law of electromagnetic induction, which states that the emf is equal to the rate of change of magnetic flux through the coil.

The maximum flux goes through the coil when it is oriented perpendicular to the magnetic field. Therefore, the maximum flux through the coil is given by:

Φmax = B A

where B is the magnetic field strength, A is the area of the coil, and Φmax is the maximum flux through the coil.

Substituting the given values,  have:

Φmax = (0.047 T) (0.23 m²) = 0.01081 Wb

When the coil is rotated, the flux through it changes from the maximum value to zero in 0.34 s. The rate of change of flux is therefore:

dΦ/dt = -Φmax/t

where t is the time taken for the flux to change from Φmax to zero.

Substituting the given values,  have:

dΦ/dt = -(0.01081 Wb) / (0.34 s) = -0.0318 Wb/s

The negative sign indicates that the flux is decreasing with time.

Finally, the emf induced in the coil is given by:

emf = -N dΦ/dt

where N is the number of turns in the coil. Since there are 10 turns in the coil,  have:

emf = -(10) (-0.0318 Wb/s) = 0.318 V

Therefore, the magnitude of the average emf induced in the coil during the 0.34 s is 0.318 V.

Answer:

the answer is a.10

Explanation:

in(No/N) = kt

No = 80 mg

N = 10 mg

t = 30 min

solve for k, then

k = 0.693/t1/2

Substitute k from above and solve for t1/2

10 min is correct.

Radioactive element keeps on decaying over the time. Decay of radioactive element always comes under first order kinetics. The element's half-life of decay of 80mg of a radioactive element decays to 10 mg in 30 mins is 10.04 minutes. The correct option is option A.

Half life tells about the time at which the radioactive material decays to half of its initial concentration.

Mathematically, the initial and final amount of radioactive material can be connected as

ln(No/N) = kt

No =initial amount of radioactive decay= 80 mg

N = final amount of radioactive decay=10 mg

t =time taken to decay= 30 min

K= rate constant

ln( 80 mg/10 mg) = k×30 min

0.069min⁻=k

k = 0.693/half life

half life=10.04min

Therefore the element's half-life of decay of 80mg of a radioactive element decays to 10 mg in 30 mins is 10.04 minutes. The correct option is option A.

Option D. Uniformitarianism is the principle stating that the physical, chemical, and biological processes at work shaping the Earth today have also operated in the geologic past. It is based on the idea that the present is the key to the past. In other words, the same natural laws that operate in the universe today have been operating since the beginning of time.

James Hutton was the first to propose this principle in the late 18th century. He suggested that the Earth was shaped by slow-acting geological forces such as erosion, sedimentation, and uplift over long periods of time. He believed that the same processes were still happening today and that they had operated in the past.

This principle is an important concept in geology because it allows scientists to interpret the Earth's history based on the processes that they observe today. By understanding how these processes work and how they have changed over time, scientists can reconstruct the history of the Earth and its environments.

Uniformitarianism has been tested and proven through many observations and experiments. For example, the study of sedimentary rocks has shown that they were formed in the past through the same processes that are observed today, such as deposition of sediment by water, wind, or ice.

Similarly, the study of volcanoes has shown that they are formed by the same processes as today, such as the movement of magma from deep within the Earth.

In conclusion, Uniformitarianism is the principle that allows us to interpret the Earth's history by observing the processes that shape it today. It is a fundamental concept in geology and has been tested and proven through many observations and experiments.
