A current of 5.29 A is passed through a Sn(NO3)2 solution for 1.30 h . How much tin is plated out of the solution?

Answers

Answer:

15.26 g of tin

Explanation:

Given that the equation of the process is;

Sn^2+(aq) + 2e ------> Sn(s)

Since 1e = 1F= 96500 C

but q =It

t is in hours so it must be converted to seconds, the SI unit of time

Hence;

119g of tin is deposited by 2 * 96500 C

xg of tin is deposited by 5.29 * 1.30 * 60 * 60

x = 119 * 5.29 * 1.30 * 60 * 60/ 2 * 96500

x = 2946106.8/193000

x= 15.26 g of tin

A current of 5.29 A is passed through a Sn(NO₃)₂ solution for 1.30 hour, the amount of tin plated is 15.26 grams.

How do we calculate mass?

Mass of any deposited susbatnce that is obtained by the passing of current will be calculated by using the Faraday's Law as:

W = ECT/F, where

W = required mass of deposited tin

C = current = 5.29 A

T = time period = 1.30hr = 4,680sec

F = faradays constant = 96500C

E = equivalent mass

Equivalent mass will be calculated as:

E = molar mass/charge on atom = 119/2 = 59.5 g/equ

On putting all these values in the above equation, we get

W = (59.5)(5.29)(4680) / 96500

W = 15.26 g

Hence mass of tin is 15.26 g.

Reacting 10.0 mL of H2(g) with 10.0 mL of C2H4(g) produces 10.0 mL of C2H6 at 1.5 atm. If the reaction produces 3.1 kJ of heat and the decrease in volume requires the heat surroundings do 7.6 J of work on the gases, what is the change in internal energy of the gases?

Answers

Answer:

the change in internal energy of the gases is  -3.0924 KJ

Explanation:

The computation of the change in internal energy of the gases is as follows;

Given that

Q = -3.1 KJ

= -3100 J

It is negative as the heat is lost from the mixture

And,

W = + 7.6 J

It is positive as the work is done in the mixture

Now we use the following equation

Delat E = Q + W

= -3100 J + 7.6 J

= -3092.4 J

= -3.0924 KJ

Hence, the change in internal energy of the gases is  -3.0924 KJ

Answers

Answer: 40 + 2x14 + 6x16 = 164g/mole

54.3g x [1mole / 164g] = 0.331moles

355mL x 1L / 1000mL = 0.355L

molarity = 0.331moles / 0.355L =

00

Explanation:

The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate  into 355 mL of water is 0.9881M

Molarity of solution is the ratio of the number of moles of the substance to the volume.

[tex]Molarity=\frac{n}{V}[/tex]

n is the number of moles of the compound[tex]n=\frac{mass}{molar \ mass}[/tex]

Mass of calcium nitrate = 54.3gMolar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol

[tex]n=\frac{54.3}{164.088 } \\n=0.331 moles[/tex]

Get the required molarity;

[tex]Molarity=\frac{0.331}{0.335}\\Molarity= 0.9881 M[/tex]

Hence the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate  into 355 mL of water is 0.9881M

2. What is the effect of branching on melting and boiling points of alkanes?

3. What ara the differences between the homolytic and heterolytic bond dissociation ? And why homolytic dissociation energy of H-H (104 KJ/mol) is lower than its heterolytic bond dissociation energy (401 KJ/mol)?

Answers

1) boiling points increase as molecular weight increase and vice versa. This is due to the increase in van der waals forces between molecules.
2) branching decreases the melting and boiling i.e increase in branching decrease boiling point and melting point. This is due to the fact that there are less point of contact between neighbouring molecules, so molecules are farther apart from each other, which means weaker van der waals(London forces) less energy is required to overcome these force of attraction.
3) In homolytic fission each of the fragment retain one of the bonded electron and radicals are made if the molecule is neutral. In heterolytic fission one fragment gets both bonding electron.
The energy for the heterolytic fission is higher because energy is not only needed to break the covalent bond but also to overcome the force of attraction between oppositely charged ions formed.

Answers

Answer:[tex][Kr]4d^{10}5s^25p^1[/tex]

Explanation:

The element Indium with atomic number 49 will have 49 protons and 49 electrons in it.

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom. The electrons are filled according to Afbau's rule in order of increasing energies and the nearest noble gas is Krypton with 36 electrons.

The electronic configuration in terms of noble gas configuration is:  

[tex]In:49:[Kr]4d^{10}5s^25p^1[/tex]

The noble-gas notation for the element indium is [Kr} 4d¹⁰5s²5p¹. The correct option is B.  [Kr] 5s2 4d10 5p1

From the question,

We are to write the electron configuration of the element Indium, using the appropriate noble gas notation.

The noble gas that comes before Indium (In) is Krypton (Kr). Therefore, the noble gas that will be used in the notation is Krypton.

Indium has an atomic number of 49 while Krypton has an atomic number of 36. This means we will fill in 13 more electrons.

The electron configuration for the element indium using the noble-gas notation is

[Kr} 4d¹⁰5s²5p¹

Hence, the noble-gas notation for the element indium is [Kr} 4d¹⁰5s²5p¹. The correct option is B.  [Kr] 5s2 4d10 5p1

What happens when a wire passes through a magnetic field?

Answers

Answer:

If a coil of wire is placed in a changing magnetic field, a current will be induced in the wire. This current flows because something is producing an electric field that forces the charges around the wire. (It cannot be the magnetic force since the charges are not initially moving).

Explanation:

Answer:

When a conductor moves through a magnetic field, there will be a generated motional emf. This is one example of Faraday's Law and it arises from the magnetic force. The voltage generated in a length of wire, presuming that the entire length moves through a uniform field, is given below.

What is the empirical formula for a compound that is comprised of 54.0% sodium, 8.50% boron, and 37.5% oxygen by mass?
A) Na2B2O3.
B) Na3BO3.
C) Na3B2O2.
D) Na4BO4.

Answers

Answer:

B) Na3BO3.

Explanation:

Hello!

In this case, since percent compositions are used to identify the empirical formula of an unknown compound, we can assume we have 54.0 g of sodium, 8.50 g of boron and 37.5 g of oxygen, and we compute the moles of each one:

[tex]n_{Na}=54.0g*\frac{1mol}{23g} =2.35mol\\\\n_B=8.50g*\frac{1mol}{11g}=0.773mol\\\\n_O=37.5g*\frac{1mol}{16g}=2.34mol[/tex]

Now, we divide by the moles of boron as those are the fewest:

[tex]Na:\frac{2.35}{0.773}=3\\\\B:\frac{0.773}{0.773}=1\\\\O=\frac{2.34}{0.773}=3[/tex]

Thus, the empirical formula is B) Na3BO3.

Would you expect salts like NaCl, which have singly-charged ions, to have larger or smaller lattice energies compared to salts like CaO which are composed of doubly-charged ions?

Answers

Answer:

NaCl has a smaller lattice energy compared to CaO

Explanation:

We have remember that lattice energy increases as the size of the ions in the ionic solid decreases. According to Oxford dictionary; lattice energy is "a measure of the energy contained in the crystal lattice of a compound, equal to the energy that would be released if the component ions were brought together from infinity."

We know that the larger the magnitude of charge on a cation the smaller in size the cation is and the size of anions increase from left to right in the periodic table. Hence Ca^2+<Na^+ and O^2- < Cl^-. Therefore the lattice energy of CaO is greater than that of NaCl.

How is an athlete's body different from a healthy body? Discuss what you learned in class today.

Answers

Answer:

Lower Heart Rate

Athletes' heart rates tend to be lower than heart rates of non-athletes. A low resting heart rate is generally a sign of good cardiovascular fitness and efficiency. A well-trained athlete may have a normal resting heart rate of only 40 beats per minute, compared with the average heart rate that ranges from 60 to 100 beats a minute.

Lower Disease Risk

Athletic types may have better overall health and be less apt to develop certain diseases. Regular exercise boosts your immune system and lowers the risk of serious health conditions such as cancer and heart disease. Physical activity can also reduce the risk of type 2 diabetes and osteoporosis while helping to manage cholesterol levels and blood pressure. You gain about two hours of additional life expectancy for each hour of regular exercise, according to the American Heart Association.

Psychological Effects

Athletes may have better mental clarity and focus than non-athletes. Exercise increases the flow of oxygen, which has a direct impact on brain function, explains the American Heart Association. Exercise can help improve your memory and reduce negative feelings, such as anger, tension, anxiety and depression.

A comprehensive study of the academic performance of North Carolina high school student-athletes in North Carolina over a three-year period attests to the positive psychological effects of athletic capabilities. Researchers discovered obvious differences between athletes and non-athletes. The study of nearly 127,000 high school students found dropout rates were lower and grade point averages were higher in students who participated in sports. The study was led by Dr. Roger Whitley in collaboration with the North Carolina High School Athletic Association.

Motivated by Excellence

Athletes, especially competitive athletes, have high ambitions. It's a trait that allows them to persevere through setbacks and failures and to come out the other side stronger. Athletes are highly motivated individuals who set their sights on a prize and are single-minded in their pursuit of excellence. They are propelled by passion to become the best they can be and the benefits of that inner drive are a higher level of self-esteem and confidence.
