How can you get a real gas to behave like the LEAST like an ideal gas (minimize attraction between particles)?

Answers

Answer 1

A real gas behaves least like an ideal gas under the conditions of low temperature and high pressure.

This is because at low temperature and high pressure molecules of gas will have negligible kinetic energy and strong force of attraction. Thus, real gas will not behave like an ideal gas.

Whereas at high temperature and low pressure a real gas will behave like an ideal gas.

Answer 2

Answer: No real gas is ideal. All molecules have a volume and intermolecular forces of attraction. So a "real molar volume" is different from an ideal molar volume.

A meteorite is found to contain two isotopes of element X, X-12, and X-14. Experimental analysis determined 95% of the element is isotope X-12, whereas 5% of the element is isotope X-14. What is the average atomic mass of element X?
Select one:

12.0 amu

14.0 amu

12.1 amu

13.0 amu

Answers

Considering the definition of atomic mass, isotopes and atomic mass of an element, the atomic mass of the element is 12.1 amu.

Definition of atomic mass

First of all, the atomic mass (A) is obtained by adding the number of protons and neutrons in a given nucleus of a chemical element.

Definition of isotope

The same chemical element can be made up of different atoms, that is, their atomic numbers are the same, but the number of neutrons is different. These atoms are called isotopes of the element.

Definition of atomic mass

On the other hand, the atomic mass of an element is the weighted average mass of its natural isotopes.

In other words, the atomic masses of chemical elements are usually calculated as the weighted average of the masses of the different isotopes of each element, taking into account the relative abundance of each of them.

Atomic mass of the element in this case

In this case, the first isotope has an atomic mass of 12 amu and a percent natural abundance of 95 %. The second isotope has an atomic mass of 14 amu and a percent natural abundance of 5 %.

Then, the average mass can be calculated as:

12 amu×0.95 + 14 amu×0.05= 12.1 amu

Finally, the atomic mass of the element is 12.1 amu.

If you are given a 0. 32 g piece of sodium metal to react with water, how many moles of hcl would it take to neutralize the sodium hydroxide produced?.

Answers

Answer:

.0139

Explanation:

The number of moles of HCl would take to neutralize the sodium hydroxide produced is equal to 0.0139 moles.

What is a neutralization reaction?

A neutralization reaction can be defined as a chemical reaction in which an acid and base react with each other to prepare salt and water.

When HCl reacts with NaOH and the resulting salt is sodium chloride and water.

HCl    +  NaOH   [tex]\longrightarrow[/tex]   NaCl   +   H₂O

The chemical reaction, chemical reaction of sodium metal and water gives hydrogen gas and sodium hydroxide:

[tex]2Na+ 2H_2O \longrightarrow 2NaOH + H_2[/tex]

Given the amount of sodium metal = 0.32 g

The moles of sodium metal = 0.32/23 = 0.0139 moles

If the 2 moles of sodium produce sodium hydroxide = 2 mol

The 0.0139 moles of sodium will produce NaOH = 0.0139

Therefore, 0.0139 moles of HCl is required to neutralize 0.0139 moles of NaOH.

2. Describe one way in which each of the items you listed in Part 1 could be at
least temporarily disrupted from equilibrium. Can you think of a way your body
could respond to restore homeostasis after one of these disruptions? (3 points)

Answers

An example of a temporary disruption from equilibrium is a temperature change, this would be compensated through sweating.

What is equilibrium?

This refers to a constant state in which forces are balanced. Inside the body, equilibrium means certain conditions such as the level of oxygen or the temperature are constant.

How is equilibrium lost?

This can be lost due to many factors, in the body, this occurs as a result of sudden changes either inside or outside the body. An example of this is sudden temperature changes, for example, if you go out of your house and it is snowing or it is very hot outside.

How is homeostasis or equilibrium restored?

The body has specific mechanisms to restore the temperature. For example, if the environmental temperature is too high the body uses sweating to keep a constant temperature.

with a given number of moles of solvent,the solution will always have the same concentration. T or F please explain why.​

Answers

Answer:

Its False

Explanation:

Its False because the concentartion would have to be the solute the thing being added. BUT if you add the equal amount of solvent and add more solute than the one you added more solute is the more concentarted.

AN EXAMPLE:

An example we have Cup A and Cup B we add the same amount of water to both cups but i add more solute to cup A (Examples of solute Salt,powder)  and i add less solute to b I balance them in a balance. and cup A is the most concentrated because It has more solute.

ANOTHER EXAMPLE:

Lets do the same thing i add the same amount of water to cup A and B I want to add the same solute but i cant since Cup A saturates At 8 Spoons And B at 6 So  cup A is most concentared

Conclusion:

So it all depends on the solute how much you add or at how many spoons you saturate.

The concentration of the solution depends upon the number of moles of solute with changing, the concentration will change. Therefore, the given statement is false.

What is the molar concentration?

The concentration of the given solution can be determined in the terms of molarity, Normality, and molality. We can easily calculate the molar concentration of a substance in a solution.

In chemistry, concentration can be described as the abundance of a constituent divided by the total volume of a mixture. The concentration can be mass concentration, number concentration, molar concentration, and volume concentration.

The concentration of the solution determined as the number of moles of a solute per unit volume of a solution is known as molarity or molar concentration.

The Molar concentration of a solution is evaluated in the following way.

Molarity (M) of the solution = Moles of solute/Volume of the Solution

Does gravity give objects their mass

Answers

Answer:

No

Explanation:

Mass affects the amount of gravity that acts on an object.

Answer:

Mass is determined by the quantity of matter in a physical object.

Mass is how much space something takes up, while weight is how much an object is acted on by a force because of gravity.

Explanation:

Gravity does not determine the mass of an object. For example, an object on the Moon would weigh less than it does on Earth because of the lower gravity, but it would still have the same mass. This is because weight is a force, while mass is the property that determines the strength of this force.

Answers

What's a combustion

It means hydrocarbon burns in presence of excess oxygen to produce carbon dioxide and heat

Hence it's exothermic∆H=+ve

As solid state is converted to gaseous so randomness increases hence it's spontaneous

Combustion is the process of combining with oxygen to form water and carbon dioxide. It is an exothermic reaction and will release energy. Thus delta H for combustion is negative.

What is enthalpy change ?

Enthalpy change of reaction is the change in heat absorbed or released by a reaction. If heat is absorbed by the system , the reaction is called endothermic and the change in enthalpy delta H is positive.

For a reaction which release energy, the change in enthalpy delta H will be negative and thus the reaction is said to be exothermic. Combustion is an exothermic reaction.

During combustion new bonds are formed between carbon and oxygen and carbon and hydrogen. Thus bond making is happend more than bond breaking. Bond breaking needs much energy than bond making.

Hence, the released energy is more form combustion and enthalpy change is negative. The process needs no more energy thus the reaction is spontaneous. Thus option C is correct.
