Explanation:

A supersaturated solution is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature. The recrystallization of the excess dissolved solute in a supersaturated solution can be initiated by the addition of a tiny crystal of solute, called a seed crystal.

Supersaturated solutions have much more dissolved solute as saturated solutions, and then they can dissolve greater solute than that of the solution can at a specific temperature.

Whenever the concentration of even a solute surpasses the concentration determined by the quantity equilibrium solubility, the chemical solution is said to be supersaturated.

.

A solution, which includes more than just the maximum quantity of solute that may be dissolved at a particular temperature is called a supersaturated solution. The injection of a microscopic crystal of solute, known as a seed crystal, can start the recrystallization of additional dissolving solute in a supersaturated solution.

Answer:

See explanation

Explanation:

The question is incomplete but i will try to help you the much i can.

You see, we already know about the fact that energy is transferred from a hotter object to a cooler object. This is largely because of the collision of the molecules of a hotter body with the molecules of a cooler body ultimately leading to a transfer of energy from the hotter body to the cooler body. This now makes the temperature of the cooler body to rise.

Keep in mind that temperature is a measure of the average kinetic energy of the molecules in a body.

Hence, since the water is at a higher temperature, energy is transferred from the water to the hand and the temperature of the hand rises accordingly.

Answer: Sodium/Na

Explanation: Molar mass is basically a measure of how heavy 6.02 x 10^23 atoms of a substance is, measured in grams.

So, if Sodium has the lowest molar mass then that means it’s molecules are very light. I’ll give a comparison: if you have 10 kilograms of bricks and 10 kilograms of feathers, will you have more feathers or bricks? Feathers, of course.

Mathematically it looks like this

50g/22.99g/mol = 2.17 mol

2.17 mol • 6.02 x 10^23 = 1.31 x 10^24 atoms

50g/58.93g/mol = 0.85 mol

You can see that as molar mass increases that the number of moles, and consequently, atoms, decreases.

Answer: 32

Explanation: but you can find them on goggle

To solve such we need to know the concept behind significant figures. Addition, subtraction, multiplication and division follow the rules of significant figures. Therefore, the correct option is option A that is 7.95 g.

Significant figures of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something.

Rules for counting the significant figures are :

Zeroes before non zero digits are not significant

Zeros between non zero digits are significant.

Zeroes after non zero digits are not significant.

When we add two decimal numbers then, the final answer would be according to the number which have least significant number.

7.94 g + 0.0132 g = 7.95g

Since among 7.94 and 0.0132, 7.94  has the least significant numbers that is 3. So, answer should have 3 significant figures, answer will be 7.95.

Therefore, the correct option is option A that is  7.95 g.

Answer:

leave little space between the molecules.

Explanation:

Matter is made up of small particles called molecules. These molecules present in matter are arranged inside its bulk.

In liquids and solids, the molecules are arranged very close together in such a way that there is only a little space between them. This is why liquids and solids are referred to as "condensed phases".

They are quite unlike gases where there is a lot of space between gas molecules.

Answer:

Chlorine has more mass than the other elements.

Explanation:

We can find the mass of each element using the following equation:

[tex] m = \eta*A [/tex]

Where:

η: is the moles

A: is the standard atomic weight

a) For carbon, we have:

[tex] m_{C} = \eta*A = 1 mol*12.011 g/mol = 12.011 g [/tex]

b) For oxygen, we have:

[tex] m_{O} = 1 mol*15.999 g/mol = 15.999 g [/tex]

c) For chlorine, we have:

[tex] m_{Cl} = 1 mol*35.45 g/mol = 35.45 g [/tex]

d) And for For hydrogen, we have:

[tex] m_{H} = 1 mol*1.008 g/mol = 1.008 g [/tex]

Therefore, chlorine has more mass than the other elements.

Answer:

Iron metal is more reactive than copper.

Explanation:

Iron metal is more reactive than copper. ... Cu is less reactive than iron, therefore, cannot replace iron from iron sulphate (FeSO4). we have already seen that iron is more reactive than copper. So that means that in this reaction, copper is less reactive than iron. That means copper cannot displace iron. It cannot kick out iron from a sulfate.

Answer:

C

Explanation:

For A, 2Al(OH)3 contains 6H on the left side of the equation but only has 3H on the right side of the equation, thus its not balanced

For B, there is 2(Al2), which is 4, on the left side of the equation but only 2Al on the right side of the equation, so it is not balanced.

For D, theres a total of 6 H on the left side of the equation as there is (OH)3 and 3H, but none of the right side, so its not balanced.

C is the correct answer as

on the left side of the equation:

2 Al(OH)3 has 2Al, 6O, and 6H

on the right side of the equation:

Al2O3 has 2Al and 3O

3 H20 has 3H and 6O

this makes a total of 2Al, 6H and 6O, which is equal to the number of each element in the left side, thus it is balanced and is the right answer.

In the future for these type of qns, you want to add up the number of each element on the left, then the ride, and see compare the numver of element they have. if the number of all the elements on both sides are the same, the equation is balanced.

Answer:

It depends upon the mass of the particles also. Assuming equal mass, then the slower moving particle gains some energy, and the faster-moving particle loses energy. However, if the slower moving particle had greater mass, it could transfer energy to the faster-moving particle.

of FeO into moles.ififdjdjjfjdjfjfjfjfjfjfjfjfjfjfjf

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.167moles are there in 12.0 g of FeO into moles.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. The stoichiometry represents the number of moles.

Mathematically,

number of moles of FeO =given mass of FeO ÷ molar mass of FeO

Molar mass of FeO  =71.8444 g/mol

mass of FeO = 12.0 g

Substituting all the given values in the above equation, we get

number of moles of FeO  = 12.0  ÷71.84

number of moles of FeO =0.167moles

Therefore, 0.167moles are there in 12.0 g of FeO into moles.

Failures and successes are part of our daily lives as humans. It can be very challenging for one to accept his or her failures and bring oneself above it.

when failure occur, the best way to reverse the negative impacts it brings is to move forward and decide on what next to do.  

The actions that must be taken in the processes should be quite productive enough to bring back the results one desired.

When the effects of failures prove irreversible, one would then give the mind a diversion and help his or herself think their way though the failure that was encountered.

Tough question.

The answer is very dependent on the temperature of the water. At 0o C, less than 5 grams is soluble in water.

The curve increases as the temperature increases. At 80oC about 35 grams  is soluble in water 100 mL of water.  So Ba(OH)2 is very soluble at higher temperatures.

Maybe the question can be resolved just a little better at room temperature. The solubility is still less than 5 grams / 100 mL. That makes it slightly soluble or more soluble than other things.

So to answer the question, you need to specify the temperature. I would say it is, but be prepared to defend your answer.
