which phase has the highest entropy?
a. gas
b. liquid
c. solid
d. aqueous

Answers

Answer 1

Answer:

Gas>Liquid>Solid

Explanation:

Entropy by definition is the degree of randomness in a system. If we look at the three states of matter: Solid, Liquid and Gas, we can see that the gas particles move freely and therefore, the degree of randomness is the highest.

Answer 2

As the reaction goes through phases, the phase that has the highest entropy is the gas state. This is further explained below. Option A is correct.

What is entropy?

A thermodynamic number that represents the inability of a system's thermal energy to be converted into mechanical work, and is commonly understood as the system's degree of disorder.

In conclusion, we have that as the reaction goes through phases, the gaseous state has the highest entropy.

polar ? polar? polar? which is polar?

Answers

Answer:

HBr

Explanation:

HBr (Hydrogen Bromide) is a polar molecule because of the unequal electronegativities of Hydrogen and Bromine atoms. Bromine has a higher electronegativity than hydrogen due to which electron bonded pair gets attracted slightly more towards bromine atom making HBr a polar molecule and resulting in a net dipole moment.

ssignment (1) Nitrobenzene has a dipole moment of 4.2 x 10-9 esu cm while phenol has a value of only 1.7 x 10-8 esu cm. However, nitrobenzene is soluble only to the extent of 0.0155mole/kg in water while phenol is soluble to the extent of 0.95mole/kgat 20C. explain this phenomenon.

Answers

Phenol can form hydrogen bonds with water since it contains O-H group but nitrobenzene can not form hydrogen bonds with water.

Polar molecules tend to be soluble in water. The greater the dipole moment, the greater the polarity of the compound. We can see that  Nitrobenzene has a dipole moment of 4.2 x 10-9 esu cm while phenol has a dipole moment of 1.7 x 10-8 esu cm.

Now, It is confusing to observe that the solubility of Nitrobenzene  in water is far less than that of phenol despite its higher dipole moment. The reason for this observation is that, phenol can form hydrogen bonds with water since it contains O-H group but nitrobenzene can not form hydrogen bonds with water.

Therefore, phenol is more soluble in pure water as a solvent compared to nitorbenzene.

Explanation:

Energy plays a key role in chemical processes. According to the modern view of chemical reactions, bonds between atoms in the reactants must be broken, and the atoms or pieces of molecules are reassembled into products by forming new bonds. Energy is absorbed to break bonds, and energy is evolved as bonds are made. In some reactions the energy required to break bonds is larger than the energy evolved on making new bonds, and the net result is the absorption of energy. Such a reaction is said to be endothermic if the energy is in the form of heat. The opposite of endothermic is exothermic; in an exothermic reaction, energy as heat is evolved. The more general terms exoergic (energy evolved) and endoergic (energy required) are used when forms of energy other than heat are involved.

A great many common reactions are exothermic. The formation of compounds from the constituent elements is almost always exothermic. Formation of water from molecular hydrogen and oxygen and the formation of a metal oxide such as calcium oxide (CaO) from calcium metal and oxygen gas are examples. Among widely recognizable exothermic reactions is the combustion of fuels (such as the reaction of methane with oxygen mentioned previously).

Answers

Answer:

The answer is C) It is given off as heat

Explanation:

        Definition of unavailable energy : energy that cannot perform work while under the current conditions; see also available energy, energy deterioration, and entropy.

How may energy become scarce?

       Energy can transform from more useful forms into less useful forms, but it cannot be created or destroyed. It turns out that some energy gets transformed into an useless form in every real-world energy transfer or transformation.

    Entropy is the measurement of the amount of thermal energy per unit of temperature in a system that cannot be used for productive work. Entropy is a measure of a system's molecular disorder or unpredictability since work is produced by organized molecular motion.

   What is Mcq for McVisible Energy? Available energy is the largest portion of low-grade energy (heat) that is available for conversion. The smallest amount of heat that needs to be rejected is referred to as unavailable energy.

     For the system with two heat reservoirs undergoing this irreversible heat transfer, entropy increases. We'll see that this implies that the ability to use the transferred energy for work has been lost. Energy is no longer available to perform work due to the increase in entropy.

The volume of a ballon is 2.85L at 1.00 atm. What pressure is required to compress the balloon to a volume of 1.70L?

Answers

Answer:

1.68 atm (if temperature is constant)

Explanation:

p1 * v1 = p2 * v2

1 * 2.85 = p2 * 1.70

2.85 / 1.70 = p2

p2 = 1.6764

There are so many gas laws like Charles's law, Avogadro’s law and many more, out of which Boyle's law is one of the most important law among all gas laws. The pressure is required to compress the balloon to a volume of 1.70L is  1.6764 atm.

What is Boyle's law?

According to Boyle's law pressure is inversely proportional to volume at constant Temperature. It is applicable only on the ideal gases. Since temperature is constant here, we can apply this law.

Mathematically

P₁V₁=P₂V ₂

P₁= initial pressure of balloon =1.0atm

V₁= initial volume balloon =2.85L

P₂=final pressure balloon =?

V ₂=final volume balloon =1.70L

Putting all values

1 × 2.85 = P₂×1.70

2.85÷ 1.70 = P₂

P₂ = 1.6764 atm

Therefore, the pressure is required to compress the balloon to a volume of 1.70L is 1.6764 atm.

how to experiment titration ​

Answers

Answer:

Add a volume of a solution of known concentration is added to a volume of another solution in order to determine its concentration. Solutions in which a few drops of phenolphthalein have been added turn from colorless to brilliant pink as the solution turns from acidic to basic.

If you want the method:

Method

1) Use a pipette and pipette filler to add 25 cm3 of alkali solution to a clean conical flask.

2) Add a few drops of a suitable indicator and put the conical flask on a white tile.

3) Fill the burette with dilute acid. Flush the tap through to remove any air bubbles. Ensure the burette is vertical.

4) Slowly add the acid from the burette to the conical flask, swirling to mix. (The mixture may at first change colour, and then back again when swirled.)

5) Stop adding the acid when the end-point is reached (when the colour first permanently changes). Note the final volume reading.

6) Repeat steps 1 to 5 until three results are repeatable (in close agreement). Ideally these should lie within 0.10 cm3 of each other.

I hope it helps.

Answer:

To conduct a titration experiment, first fill the burette with an acid or base solution of known concentration. After that, take a burette reading from the top of the miniscus down to the bottom. Then, underneath the burette, place a flask containing an unknown concentration of acid or base. After that, fill the flask halfway with the appropriate indicator and shake it up. Add your titrate to the flask one drop at a time while stirring constantly. Continue to add the titrate until the color change is noticeable. Finally, take one more look at the burette to make sure everything is correct.

List the metals that form only one type of ion (that is, metals whose charge is invariant from one compound to another). What are the group numbers of these metals

Answers

this question is in reference to the formation and naming of ionic compounds. Specifically, they want you to give examples of three ionic compounds with a metal to nonmetal ratio of 2 to 1. That means we need to have two metal atoms to metal ions, which are typically cat ions for every one non metal atom or an ion. In order for this to occur, we need to have the metal with half the charge of the nonmetal or the non metal with double the charge of the metal. So an example might be something like sodium sulfide. Sodium has one valence electron. It can give up sulfur needs to valence electrons in order to achieve an octet. So we need to. Sodium seems to give up one electron each to total so that sulfide can achieve an octet. Another one might be potassium oxide. Similar scenario. We've got potassium giving up one valence electron oxygen requiring too. So we need to potassium to supply the to valence electrons that oxygen needs to achieve an octet and lithium. Also in Group one A and alkali metal wants to give up just one valence electron to achieve an octet well to achieve, I guess a duet to be more like helium, and so it gives up one. If we have two of them, then we can provide the to valence electrons that sulfur needs. So this is sodium sulfide, potassium oxide and lithium sulfide. Remember when we name Ionic compounds? We named the Cat Ion with the name of the element and the anti on with the name of the Element, but with the ending oven of ID, a suffix of ID because each one of the cat ions donated their valence electrons to the anti on so the an ion could achieve an octet. Then all of the's will have an octet of valence electrons. Sulfur had six sodium had one. There were two of them, so we have a total of eight.

The metals that can form only one type of ion are Li, Al, Ca, Ba, Rb, W,Na, Mg and  Sr. They are called alkali metals.

Cobalt, Co is stable in both +2 and +3 oxidation state. So it can variable.

Lithium, Li only have +1 charge. So it is invariable from one compound to other.

Lead, Pb is variable as it has +2, +4 charge in which it is stable.

Pd has +2, +4 charge in which it is stable. So, It is variable.

Copper, Cu has +1, +2 charge. It is also variable. Potassium, K has only +1 charge. It is invariable. Aluminum, Al has only +3 charge. It is invariable.

Cesium, Cs is only stable in +1 charge. It is invariable. Molybdenum, Mo is stable in +4 and +6. It is variable. Calcium, Ca and Barium Ba are stable in +2 charge. It is invariable.

Rubidium, Rb is stable in +1 charge. It is invariable. Tungsten, W is stable in +6 charge. It is invariable. Iron, Fe is stable in +2, +3 charge. It is variable. Sodium, Na is stable in +1 charge. It is invariable. Mg and Sr are stable in +2 charge. It is invariable. Vanadium, V has +2, +3, +4, +5 charges. So, It is variable.
