At 25C and 795 torr, carbon dioxide has a solubility of 0.0356 M in water. What is the solubility at 25 C and 2070 torr? ____ MI know that at a given temperature, the solubility of a gas in a liquid is directly proportional to its pressure but how would that be set up in an equation..?

Answers

Answer 1

Answer: If you want to do real scientifically, the equation is
p = kc.
We evaluate k = p/c and plug in the first set of conditions.
k = 795/0.0356 = 22,331

Then p = kc and solve for c
c = p/k = 2070/22,331 = 0.093

Answer 2

Answer:

The mixing of solute in the solvent is called solubility. In a solution, there are two types of components, these components are solute and solvent.

Solute - a component that presents in less amount.
Solvent - a component that is present in a large amount.

According to the question, the torr is defined as the torr is a unit of pressure based on an absolute scale, defined as exactly 1/760 of a standard atmosphere.

The equation is

$p = kc$

hence, $k = (795)/(0.0356) = 22,331$

After solving the equation,

$c = (p)/(k) \n\n= (2070)/(22,331)\n\n = 0.093\n$

Hence, the solubility is 0.093.

15 Which statement describes the particles of an ideal gas, based on the kinetic molecular theory?(1) The motion of the gas particles is orderly and circular.
(2) The gas particles have no attractive forces between them.
(3) The gas particles are larger than the distances separating them.
(4) As the gas particles collide, the total energy of the system decreases.

Answers

Ans: (2) The gas particles have no attractive forces between them.

The kinetic theory explains the behaviour of a hypothetical ideal gas. It explains pressure in terms of the collision of gas particles against the walls of the container which it occupies.

The kinetic theory of gases is based on three main postulates:

1) The collision between gas particles is elastic i.e. no energy is lost or gained

2) The gas particles are treated as point masses i.e. the volume occupied by the gas particles is negligible when compared to the volume of the container

3) There are no attractive or repulsive forces between particles.

The statement that describes the particles of an ideal gas, based on the kinetic molecular theory is $\boxed{\left( {\text{2}} \right){\text{ The gas particles have no attractive forces between them}}}$ .

Further Explanation:

Kinetic theory of gases depicts gas as a large number of particles that are in continuous random motion. It explains the macroscopic properties of gases by taking into account their molecular composition and motion.

Postulates of kinetic theory of gases:

i) 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.

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

iii). 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.

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

v). No interaction occurs between different molecules of gas during collisions.

(1) The motion of the gas particles is orderly and circular.

The molecules of a gas move randomly in all directions so their motion is not orderly and circular.

(2) The gas particles have no attractive forces between them.

The molecules of a gas move randomly in all directions so their motion is not orderly and circular.

(3) The gas particles are larger than the distances separating them.

The particles of gas are very small and are situated far away from each other. So the distance between the particles is larger than their size and not vice-versa.

(4) As the gas particles collide, the total energy of the system decreases.

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 option (2) describes the particles of an ideal gas on the basis of the kinetic molecular theory.

Which end of a water molecule is positive and which end is negative and why?

Answers

The region or the end of water molecule that is partially positive would be where the Hydrogens are. The end that is partially negative, is where the Oxygen is. These partial charges, are because of the large electronegativity differences present between the hydrogens and Oxygen in the molecule. Thus unequal electron distribution or sharing occurs between the atoms in the molecule causing it to be polar and possess the partial charges.

C. average decrease in the temperatures near Earth's surface
D. a decrease in carbon dioxide emissions

Answers

Answer: The correct answer is A. average increase in the temperatures near Earth's surface

Explanation: The reason this is correct is that global warming is it getting hotter, logically the temperatures near Earth's surface will be getting hotter as well. Hope this helps
