Predict what kind of energy process happens when Lye, NaOH(s) is put in water and the water gets hot

Answers

Answer 1

Answer:

Answer:

Exergonic process

Explanation:

A reaction in which the change in free energy is negative is what is termed an exergonic reaction. Energy is released into the surrounding medium in this type of reaction.

When pellets of NaoH is dissolved in water, energy in the form of heat is released into the medium and the solution gets hot.

Hence, the dissolution of NaoH in water is said to be exergonic.

Answer 2

Answer: what happens is that the sodium solution when put in water reacts and creates thermal energy .

What’s the easiest way to add energy to matter

Answers

Answer:

The easiest way is to heat matter which raises its internal energy andso the mass as well. Another possibility is to accelerate matter as in case of protons or heavy ions in the LHC, Protons ,for example , are accelerated to the energies of 6500 GeV which means increase of the rest mass by a factor of almost 7000

Which sample has particles with the lowest average kinetic energy?(1) 1.0 g of I2 at 50.°C
(2) 2.0 g of I2 at 30.°C
(3) 7.0 g of I2 at 40.°C
(4) 9.0 g of I2 at 20.°C

Answers

The question asks average kinetic energy. So it is only related with the temperature. The higher temperature is, the higher kinetic energy is. So the answer is (4).

Answer : Option 4) 9.0 g of $I_(2)$ at 20°C

Explanation : Usually the average kinetic energy depends upon the state of the matter. Considering about the iodine at lower temperature the kinetic energy is found to be low. Whereas at higher temperature has higher kinetic energy value.

From the kinetic energy equation it can be easily related that K.E. is directly proportional to the temperature.

In the process of electrolysis, current can flow through a liquid because A. water molecules become negatively charged. B. hydrogen is electrically neutralized in the solution. C. negative ions are attracted to the anode. D. cations of the electrolyte accumulate at the positive electrodes.

Answers

B. Hydrogen is electrically neutralized in the solution. Hydrogen is a chemical element with symbol H and atomic number 1. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table.

The correct answer is

C. Negative ions are attracted to the anode.

Which statement describes the particles of an ideal gas based on the kinetic molecular theory?(1) The gas particles are relatively far apart and have negligible volume.
(2) The gas particles are in constant, nonlinear motion.
(3) The gas particles have attractive forces between them.
(4) The gas particles have collisions without transferring energy.

Answers

$\boxed{\left( {\text{1}} \right){\text{ The gas particles are relatively far apart and have negligible volume}}}$ is the correct statement that describes the particles of an ideal gas on the basis of kinetic molecular theory.

Further Explanation:

Kinetic theory of gases

It defines gas to be considered as a large number of particles. These particles move randomly in all directions. It explains the macroscopic properties of gases by considering their molecular composition and motion.

Postulates:

(a) The gas molecules are very small and are located far apart from each other. Most of the volume occupied by the gas is an empty space.

(b). The molecules of the gas are in rapid random motion. These can move in all directions.

(c). The gas molecules undergo collisions with each other and with the walls of the container. The collisions between molecules and container walls are responsible for the pressure of the gas.

(d). There is no loss of kinetic energy when gas molecules collide so their collisions are known as perfectly elastic.

(e). No interaction occurs between different gas particles during collisions.

(1) The gas particles are relatively far apart and have negligible volume.

The size of gas particles is very small and therefore these have negligible volume. Moreover, these molecules are far away from each other.

(2) The gas particles are in constant, nonlinear motion.

The motion of the gas particles occurs randomly in all directions so they can not be in constant, nonlinear motion.

(3) The gas particles have attractive forces between them.

The particles of gas have no interaction with each other. So no attractive forces are present between them.

(4) The gas particles have collisions without transferring energy.

The collisions of gas molecules are considered to be perfectly elastic. So the total energy of the system remains constant. It neither increases nor decreases.

Therefore the correct statement is (1).

Keywords: kinetic theory of gases, collisions, energy, constant, attractive forces, particles, molecules, volume, random motion, perfectly elastic, negligible.

Answer:

(1) The gas particles are relatively far apart and have negligible volume

Explanation:

The Kinetic Molecular Theory was formulated to explain the behaviour of ideal gases. The main postulates of the theory are:

-The volume occupied by the gases is negligible when compared to the distance between them

- They do not experience any intermolecular forces of attraction or repulsion

-The collision between gas particles is completely elastic

-The gas particles are in constant random motion

Therefore the first statement which suggests that the gas particles are relatively far apart and have negligible volume is in accordance with the theory
