What is the mole ratio of NH3 to N2?

Chemistry

Ksenya-84 [330]3 years ago
8 0
To answer this question a balanced chemical equation is necessary. The correct equation is: N2 + 3H2 = 2NH3
From this equation, one mole of nitrogen react with 3 moles of hydrogen to give 2 moles of ammonia.
Therefore, the mole ratio of NH3 to N2 is 2:1

When 1.0 mole of MgSO4 is dissolved in water contained in a calorimeter, the temperature of the water and dissolved ions increas
KatRina [158]

Answer: negative , from , to , exothermic

Explanation:

An endothermic reaction is a type of chemical reaction in which energy is absorbed from the surrounding. The temperature of the surrounding decreases.

An Exothermic reaction is a type of chemical reaction in which energy is released into the surrounding. The temperature of the surrounding increases.

Endothermic reactions are those in which heat is absorbed by the system from the surroundings and exothermic reactions are those in which heat is released by the system to the surroundings. \Delta H  for Endothermic reaction is positive and  

As on dissolution of salt, the temperature of water increases, the heat has been released from system into surroundings and thus \Delta H is negative.

Jennie observes her brother playing pool and has a theory that the potential energy in the pool stick is transformed into kineti
Shkiper50 [21]

A lot of theories exist in the world today regarding energy. The statement that explains how she can prove her theory is below:

  • He could measure the potential energy when the pool stick is pulled back before moving to strike the pool ball, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of kinetic energy and potential energy to prove there was a transformation of potential energy to kinetic energy.

Potential energy is known to be of position relative, and kinetic energy is motion relative.

The relationship that exist between the two is their ability to transform into one another. That is potential energy transforms into kinetic energy, and kinetic energy converts into potential energy, and vice versa

If an outside force acts upon an object with potential energy, that force is said to change the potential energy into kinetic energy.

The full question is below

Jennie observes her brother playing pool and has a theory that the potential energy in the pool stick is transformed into kinetic energy when he hits the ball.

Which explains how she can prove her theory?

A

She could measure the potential energy in the motionless ball on the pool table, and she could measure the potential energy of the pool stick as it moves to strike the ball. These total of these two measurements will be equal to the kinetic energy in the pool ball as it moves, and this proves there was a transformation of energy.

B

She could measure the potential energy when the pool stick is pulled back to strike the pool ball, and then she could measure the kinetic energy in the pool stick as it moves to strike the ball. The potential energy in the pool stick and the kinetic energy in the pool stick should be equal, proving there was a transformation of energy.

C

She could measure the potential energy when the pool stick is pulled back before moving to strike the pool ball, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of kinetic energy and potential energy to prove there was a transformation of potential energy to kinetic energy.

D

She could measure the potential energy of the pool ball when it was sitting on the table, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of potential energy in the motionless ball and kinetic energy in the ball after the stick strikes it to prove there was a transformation of potential energy to kinetic energy.:

What example of scientific thinking does Bohr response best indicate
Ugo [173]

Answer:

The Bohr model shows the atom as a central nucleus containing protons and neutrons with the electrons in circular orbitals at specific distances from the nucleus (Figure 1). These orbits form electron shells or energy levels, which are a way of visualizing the number of electrons in the various shells
