Answers

Answer 1

Answer:

According to the kinetic theory of gases, in an ideal gas between two successive collisions, a gas molecule travels in a straight line.

Answer 2

According to the kinetic theory of gases, an ideal gas molecule move in a straight line between two successive collisions.

What is the kinetic theory of the gases?

The kinetic theory of gases says that the gas is many large numbers of subatomic particles, which randomly motion always.

They move on a straight plane and only change their path when they collide with other molecules or the container's walls.

Thus, according to the kinetic theory of gases, an ideal gas molecule move in a straight line between two successive collisions.

Explain why the vapor pressure of a solution differs from that of the pure solvent
Explain why the freezing point of a solution differs from that of the pure solvent
Explain why the boiling point of a solution differs from that of the pure solvent

Answers

Answer:

Answer one:
Solute particles block some of the ability of liquid particles to evaporate. We can then conclude, solutions of solid solutes typically have a lower vapor pressure than pure solvents.

Answer two:
Solutions freezing points are lower than of the pure solvent or solute because freezing (becoming a solid) creates order and decreases entropy.

Answer three:
The presence of solute particles decreases the vapor pressure of the liquid solvent, this means a higher temperature is needed to reach the boiling point.

In a heavier nucleus, the repulsive force between the protons is very high. For stability, the nuclear force must dominate this electrostatic repulsive force. This is possible if the number of neutrons is greater than number of protons.

When a solution of mgcl2 and one of agno3 are mixed, the net ionic equation is:

Answers

When a solution of MgCl₂ and a solution of AgNO₃ are mixed, the net ionic equation obtained is:

2Cl¯(aq) + 2Ag⁺(aq)  —> 2AgCl(s)

What is a chemical equation?

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

How to write the net ionic equation

In solution

MgCl₂(aq) —> Mg²⁺(aq) + 2Cl¯(aq)

AgNO₃(aq) —> Ag⁺(aq) + NO₃¯(aq)

The reaction proceeds as follow

MgCl₂(aq) + AgNO₃(aq) —>

Mg²⁺(aq) + 2Cl¯(aq) + 2Ag⁺(aq) + 2NO₃¯(aq) —> 2AgCl(s) + Mg²⁺(aq) + NO₃¯(aq)

Cancel out the spectator ions (i.e Mg²⁺ and NO₃¯) to obtain the net ionic equation

2Cl¯(aq) + 2Ag⁺(aq)  —> 2AgCl(s)

https://brainly.com/question/7181548

When a solution of MgCl₂ and one of AgNO₃ are mixed, the net ionic equation is 2Cl¯(aq) + 2Ag⁺(aq) → 2AgCl(s).

What are net ionic reactions?

Net ionic reactions are those reactions in which each species are written in their respective ions form except the spectator ions.

Given chemical reaction is:

MgCl₂(aq) + 2AgNO₃(aq) → 2AgCl(s) + Mg(NO₃)₂(aq)

Ionic form of the given reaction will be written as

Mg²⁺(aq) + 2Cl¯(aq) + 2Ag⁺(aq) + 2NO₃¯(aq) → 2AgCl(s) + Mg²⁺(aq) + NO₃¯(aq)

Spectator ions are those which are commonly present on both side of the reaction and for this reaction they are Mg²⁺ and NO₃¯. So the net ionic reaction will be:

2Cl¯(aq) + 2Ag⁺(aq) → 2AgCl(s)

Hence required net ionic reaction is 2Cl¯(aq) + 2Ag⁺(aq) → 2AgCl(s).

Answers

It should be 24 they both have to be equally the same

The mass of hydrogen atoms in the compound would be 2 grams.

Stoichiometric calculation

The carbon atoms in the compound have a mass of 24 grams.

One carbon atom has a mass of 12 grams. Thus, there are two (12 x 2 = 24) carbon atoms in the compound.

This means that there are also two hydrogen atoms in the compound. One hydrogen atom weighs 1 gram. Hence, the mass of the hydrogen atoms in the compound will be 2 grams.

How many liters of carbon gas are in 13.7 moles of carbon dioxide gas at STP?

Answers

At STP

1 mol weighs 22.4L

No of moles=13.7mol

Total volume:-

13.7(22.4)306.88L[/tex]

The volume of gas occupied by 13.7 moles at STP is 306.88L.

What is STP?

STP stands for standard temperature and pressure. STP refers to a specific pressure and temperature used to report on the properties of matter.

According to IUPAC( International Union of Pure and Applied Chemistry), it is defined as -

Temperature of 0 degree celsius (273K)Pressure of 1 atm

It is generally needed to test and compare physical and chemical processes where temperature and pressure plays an important role as they keep on varying from one place to another.

One mole of a gas under STP conditions occupies a volume of 22.4L.

Given,

Moles of carbon dioxide gas = 13.7 moles

We know that,

1 mole of a gas occupies 22.4 L of volume at STP.

Thus, 13.7 moles will occupy 13.7 × 22.4 L

                                              = 306.88 L

Therefore, the volume of gas occupied at STP is 306.88L.

A mixture of three gases has a total pressure of 94.5 kpa. if the partial pressure of
the 1st gas is 65.4 kpa and the partial pressure of the 2nd gas is 22.4 kpa, what is the
partial pressure of the 3rd gas of the mixture?

Answers

Answer: 6.7 kPa

Explanation:

Pressure Total = P(partial 1) + P(partial 2) + P(partial 3) →

94.5 kPa = 65.4 kPa + 22.4 kPa + P(partial 3) →

6.7 = P(partial 3) :)

Given:-Partial pressure of 1st gas ,P[tex]_1[/tex]= 65.4 kpapartial pressure of 2nd gas ,P[tex]_2[/tex]= 22.4 kpaTotal pressure,P[tex]_o[/tex] = 94.5 kpa

To Find :-partial pressure of the 3rd gas,P[tex]_3[/tex]

Solution:-

According to the Dalton's law of partial pressures the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures exerted by each individual gas in the mixture.

So, P[tex]_o[/tex] = P[tex]_1[/tex]+ P[tex]_2[/tex]+ P[tex]_3[/tex]

[tex]\longrightarrow[/tex]94.5 = 65.4+ 22.4 + P[tex]_3[/tex]

[tex]\longrightarrow[/tex]94.5 = 87.8+ P[tex]_3[/tex]

[tex]\longrightarrow[/tex] P[tex]_3[/tex] = 94.5 - 87.8

[tex]\longrightarrow[/tex]P[tex]_3[/tex] = 6.7 kpa

Therefore, partial pressure of the 3rd gas of the mixture is 6.7 kpa .

Explain why air resistance is a contact force and gravity is a non-contact force.

Answers

Answer:

The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object. This force will frequently be neglected due to its negligible magnitude (and due to the fact that it is mathematically difficult to predict its value). It is most noticeable for objects that travel at high speeds (e.g., a skydiver or a downhill skier) or for objects with large surface areas. Air resistance is a contact force.

The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object. All objects upon earth experience a force of gravity that is directed "downward" towards the center of the earth. Gravitational force is considered to be a non-contact force because it is an attracting force which does not include contact between the objects to exert force

Answers

Answer: 373 mL

Explanation:

Since there is no change in pressure, the formula: V / T = V / T can be used.

However, you must first convert the temperatures to Kelvin by adding 273 to them:

(19 + 273) = 292K and (90 + 273) = 363K.
