What is "a sea of electrons"

Answers

Answer:

In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.

Taku mixed some water and juice crystals to make a fruit drink.
(a) The solute is
(b) The solvent is

Answers

This is not a math question but I’ll help. The solute is what you are dissolving something in. The solvent is what is dissolved. So if you are dissolving juice crystals IN water the juice crystals would be the solvent and the water would be the solute

According to the concept of solubility, thing which dissolves is solute and in which it is dissolved is solvent , hence juice crystals are solute and water is solvent.

What is solubility?

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

Calcium carbonate, Caco is able to remove sulfur dioxide, SO, from waste gases by a reaction in
which they react in a 1:1 stoichiometric ratio to form equimolar amounts of Caso, When 255 gof
CAC, reacted with 135 g of So, 198 g of caso, were formed. Determine the percentage yield of Caso3

Answers

Answer:  Detailed problem with lots of assumptions.  Please see below.  Percent yield is 100% (!?, so check my work).

Explanation:

Some information is missing from the problem statement.  I'll make some assumptions to solve the problem, so this answer depends on those assumptions.

"Calcium carbobnate" is CaCO3, not CaCO, which is obtained by calcining (heating) CaCO3:

  CaCO3 = CaO + CO2

The CaO can then be reacted with SO2 to form calcium sulfate, CaSO4 (not CaSO, as per the following balanced equation:

2CaO + 2SO2 + O2 = CaSO4

[Note:  It also reacts with any SO3 molecules bouncing around, as does happen in flue gases to also form CaSO4]

The following assumes we have 255 grams of CaCO3, not CAC, whatever that stands for.

We have 135g of SO2, not SO.

This also assumes that it is CaSO4 that is produced (not CaSO), 198 grams.

Since is a two step reaction sequence, we need to first calculate the moles of Ca) produced from the CaCO3.  It is a 1:1 molar ratio, and we have (255g/100.1g/mole) = 2.548 moles of CaCO3.  This will produce 2.548 moles of CaO, for use in the second reaction.

2CaO + 2SO2 + O2 = 2CaSO4

This tells us we'll produce 1 mole of CaSO4 for every 2 moles of CaO, a 1:2 ratio.  It also states that 2 moles of SO2 are consumed for every 2 moles CaO, a 1:1 ratio.

We have 2.548 moles of CaO, so would need the same moles of SO2 to fully react.  However, we only have (135g/64.1 g/mole) = 2.107 moles of SO2.  The SO2 will be the limiting reagent, so the theorectical yield will be based on this reactant, which will consume 2.107 moles of CaO, leaving 0.44 moles (24.7 g) of CaO behind.

The balanced equation tells us that 2.107 moles of CaO should produce 2.107 moles of CaSO4, which is (2.107moles)*(136.1 g/mole) = 198 grams of CaSO4.  We actually got 198 grams, so the yield is 100%  [Nice work].

b. Exothermic, ΔH is negative
c. Endothermic, ΔH is negative
d. Endothermic, ΔH is positive

Answers

Since the heat of solution of KI is 20.3 kJ/mol, the answer to the question is a. Exothermic, ΔH is positive

There are two types of chemical reactions namely exothermic and endothermic reaction.

For exothermic reactions, heat is released. So, ΔH is positiveFor endothermic reactions, heat is absorbed. So, ΔH is negative

Given the heat of solution of KI as 20.3 kJ/mol.

Since it is positive, the reaction is exothermic and  ΔH is positive

Since the heat of solution of KI is 20.3 kJ/mol, the answer to the question is a. Exothermic, ΔH is positive

Explanation:

Carbon-carbon covalent bonds, such as the ones in carbohydrates and lipids, are weak and have potential energy.

What is covalent bond?

In chemistry, a covalent bond is a chemical connection between two ions or atoms in which their respective electron pairs are shared. A molecular bond is another name for a covalent link.

Several other chemical species, including radicals and macromolecules, may also include this kind of connection. Irving Langmuir invented the term "covalence" around 1919 to characterize the quantity of electron pairs exchanged by nearby atoms, but the phrase "covalent bond" wasn't used until 1939. Carbon-carbon covalent bonds, such as the ones in carbohydrates and lipids, are weak and have potential energy.

Both fission and fusion can be regarded as nuclear reactions that brings about production of  energy. However they have different applications.

Fission can be explained as the splitting of a heavy as well as unstable nucleus into two nuclei , but this nuclei are lighter compare to the mother nucleus.

Fusion on the other hand can be regarded as a  process involving  two light nuclei coming together to form one and then  release vast amounts of energy

How many moles of sodium chloride are in a 321.8 g sample?

Answers

Answer:

One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.

The number of moles of sodium chloride in a 321.8 g sample is 5.5 moles. Details about number of moles can be found below.

How to calculate number of moles?

The number of moles of a substance in a particular mass of that compound can be calculated as follows:

no of moles = mass ÷ molar mass

molar mass of NaCl = 58.5g/mol

No of moles of sodium chloride = 321.8g ÷ 58.5g/mol

no of moles = 5.5 moles

Therefore, the number of moles of sodium chloride in a 321.8 g sample is 5.5 moles.

Answer:  K only has 1 valence electron.  It will leave with only a little effort, leaving behind a positively charged K^+1 atom.

Explanation:  A neutral potassium atom has 19 total electrons.  But only 1 of them is in potassium's valence shell.  Valence shell means the outermost s and p orbitals.  Potasium's electron configuration is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1.  The 4s orbital is the only orbital in the 4th energy level.  So it has a valency of 1.  This means this electron will be the most likely to leave, since it is the lone electron in the oyutermost energy level (4).  When that electron leaves, the charge on the atom go up by 1.  The atom now has a full valence shell of 3s^2 3p^6, the same as argon, Ar.

The half life of iodine-131 is 8.040 days. What percentage of an iodine-131 sample will remain after 40.20 days?

Answers

The percentage of an iodine-131 sample that will remain after 40.20 days is 3.125%

We'll begin by calculating the number of half-lives that has elapsed. This can be obtained as follow:

Half-life (t½) = 8.040 days.

Time (t) = 40.20 days

Number of half-lives (n) =?

[tex]n = \frac{t}{t_{1/2}} \\\\n = \frac{40.20}{8.040}\\\\[/tex]

n = 5

Thus, 5 half-lives has elapsed.

Finally, we shall determine the percentage of an iodine-131 sample that remains. This can be obtained as follow:

Number of half-lives (n) = 5

Percentage remaining =?

[tex]N = \frac{1}{2^{n} } * N_{0} \\\\N = \frac{1}{2^{5} } * N_{0} \\\\N = \frac{1}{32} * N_{0}\\\\[/tex]

Divide both side by N₀

[tex]\frac{N}{N_{0}} = \frac{1}{32} \\\\\frac{N}{N_{0}} = 0.03125\\\\[/tex]

Multiply by 100 to express in percent

[tex]\frac{N}{N_{0}} =[/tex] 0.0312 × 100

= 3.125%

Therefore, the percentage of an iodine-131 sample that remains is 3.125%
