A chemist is studying the properties of a gas under various conditions. He observes that when the gas is at room temperature and low pressure, it behaves as an ideal gas. When the gas is cooled to 10 kelvin (–263ºC) and is placed under high pressure, however, it deviates significantly from an ideal gas. There are multiple reasons for this phenomenon. Check all of the correct reasons below. The ideal gas model assumes that gas particles experience no intermolecular attractions and these forces cause the gas to deviate from ideal behavior. At very low temperatures, gas particles move slowly. At very high pressures, gas particles are very close together. Gases placed under high pressure will undergo deposition, changing from a gas to a solid.

Answer:

C2H5

Explanation:

you first find the number of moles of both substances then divide by the lowest number in this case carbon was 1 and hydrogen was 2,515... then you multiply by a whole number which was 2 then it was now C2H5

Answer:

For every 1 Ca(NO3)2 there are six (2 * NO3 or 2 * 3 O) oxygens. If you have 3 mole of Ca(NO3)2 then you have 18 mole of oxygen atoms (3*6).

Answer:

I will assume that the moles are all mistyped and will change them to:

4.64, 25.9, and 2.73.

15.2 liters

Explanation:

Both situations can be described using the ideal gas law:  

PV=nRT,

where P, V, and T are the pressure, volume, and temperature (in degrees K).  n is the number of moles.  R is the gas constant.

First NO2 :      P1(25.9L) = (4.64moles)RT

Second NO2: P2V2 = (2.73moles)RT2

Divide one equation by the other:

(P1(25.9L)  =  (4.64)RT1)      

  P2V2 = (2.73)RT2          

The temperatures, pressures, and gas constants are unchanged, so we can cancel those to obtain:

(25.9L)/V2 = (4.64/2.73)

V2 = (25.9L)(2.73/4.64)

V2 = 15.2 Liters

Explanation:

Molality of a solution is the number of moles of solute dissolved in 1 Kg of the solvent. Thus, if one gram molecule of a solute is present in 1 kg of the solvent.

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration

Answer:

C: 10m

Explanation:

Work Done = Force x Distance

500 = 50 x Distance

To get to 500 multiply 50 by 10!

So, the box slid 10m.

Answer:

441.81 mL

Explanation:

P1 x V1 = P2 x V2

V2 = P1 x V1 / P2

V2 = 608 x 545 / 750

V2 = 331360 / 750

V2 = 441.81 mL

Answer + Explaination: A beam of light bends when it passes into a new medium because light travels slower in denser medium.

When an atom of chlorine forms an ionic bond with an atom of sodium, the

atom of sodium loses an electron.

This is also known as electrovalent bond and it is the bond which occurs

as a result of elements gaining or losing electrons in a reaction.

An atom of chlorine forming an ionic bond with an atom of sodium,means

the atom of sodium will have to lose an electron in other to achieve a

The appearance of ions in solution makes a solution to conduct electricity.

Conductivity refers to the flow of current through a solution.

1) There is an evidence that reaction has occurred because of the formation of a precipitate

2) The conductivity decreases as more H2SO4 was added.

3) The indicator of the number of ions in the solution is the current recorded.

4) This evidence indicates that a reaction has occurred because the formation of a precipitate decreases the current.

5)  Ba(OH)2(s) ---->  Ba^2+(aq) + 3OH^-(aq)

H2SO4(aq) ---> 2H^+(aq) + SO4^2-(aq)

6) When the conductivity is at the minimum, It means that the   Ba(OH)2 is largely undissociated.

7) It does not conduct at a low point because there are no ions in solution.

8) It conducts more before and after this minimum point because of more ions in solution.

Explanation:

3.Apply the ideal gas law: PV = nRT solving for n. Here you can use the pressure given in atm, but you must choose the 0.0821 atm L/mole K gas constant. Or you can change 4.5 atm to 3420 mm Hg and use the 62.4 mmHg L/mole K gas constant. You must change 500 ml to 0.5 L because both gas constants have units in L, and so the volume must be in liters so it can cancel out. And of course, you must change the temperature to Kelvin.

a. n = (4.5atm)(0.5L)

moliK)(298K) = 0.092 mole (0.0821 atmiL

b. 0.092mol 32g

⎛⎝⎜ ⎞⎠⎟ = 2.9 g

1mol

c. Remember that D = mass

vol so D = 2.9g

0.5L = 5.9 g/L

Measurement units are the defined units used for the particular dimensions and proportions. 3500 milliseconds are there in seconds.

Time is defined as the rate of things occurring or taking place and is given by seconds, minutes, hours etc.

Using  the conversion factor the relation between the seconds and milliseconds is:

1 second = 1000 miliseconds

Convert 3.5 seconds into milliseconds using conversion factor:

[tex]\begin{aligned}3.5 \;\rm seconds &= 3.5 \times 1000 \\\\&= 3500 \;\rm miliseconds\end{aligned}[/tex]

Answer:

Law of conservation of linear momentum :- when there is no any external force applied on a system of particles then , momentum of system of particles will be conserved or you can say that if external force is zero. Then momentum of system of particles in intially = momentum of system of particles in finally

Explanation:

According to Newton's second law of motion, because no external force occurs on the system, The change in momentum is equal to zero; hence, the linear momentum is conserved. The entire linear momentum of an isolated system, that is, a system that is not subjected to any external forces, is conserved.

1. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.

2. It must be conserved in an isolated system because isolated systems do NOT exchange matter or energy with their surroundings.
