Enter the full electron configuration for S2�. What is the atomic symbol for the noble gas that also has this electron configuration?

Answers

Answer 1

Answer:

1. Electronic configuration of sulphide ion S²¯ (18) => 1s² 2s²2p⁶ 3s²3p⁶

2. Ar

Explanation:

1. S²¯ simply indicates that the sulphur atom (S) has gained two extra electrons.

Thus we shall write electron configuration of sulphur (S) and sulphide ion (S²¯) as follow:

The electronic configuration of S²¯

S (16) => 1s² 2s²2p⁶ 3s²3p⁴

S²¯ (18) => 1s² 2s²2p⁶ 3s²3p⁶

2. Determination of the noble gas element that has the same electronic configuration as S²¯.

This is illustrated below:

Sulphur (S) has 16 electrons while the sulphide ion (S²¯) has extra 2 electrons making it to have a total electron of 18. Observing the elements in the periodic table, only Argon has 18 electrons with electronic configuration as:

Ar (18) => 1s² 2s²2p⁶ 3s²3p⁶

Therefore, sulphide ion (S²¯) has the same electronic configuration as Argon (Ar).

An unopened 350 mL can of diet Dr. Pepper will float in a lake. However, it’s also true that an unopened 350 mL can f regular Dr. Pepper will sink in the same lake! Based on these two facts, which type of soda is the least dense? Explain your answer.

Answers

Answer:

Diet Dr. Pepper

Explanation:

The density of an object and the liquid involved determines if that particular object will float or sink in the particular liquid. An object will FLOAT if its density is lower than that of the liquid substance while it will SINK if its density is higher than that of the liquid substance.

In this case, water (lake) is the liquid substance. According to the question, an unopened 350 mL can of DIET Dr. Pepper will float in a lake because it is less dense than the water while an unopened 350 mL can of REGULAR Dr. Pepper will sink because it is more dense than water.

Hence, the DIET type of soda is the least dense

In run 1, you mix 7.9 mL of the 43 g/L MO solution (MO molar mass is 327.33 g/mol), 3.13 mL of the 0.040 M SnCl2 in 2.0 M HCl solution, 5.49 mL of 2.0 M HCl solution, and 3.43 mL of 2.0M NaCl solution. What is the [H3O+]? Remember that there is a contribution of H3O+ from two solutions.

Answers

Answer:

Concentration of H3O⁺  [H3O⁺] = 0.864 M

Explanation:

Given that:

The mass concentration of MO = 43 g/L

The volume of MO = 7.9 mL = 7.9 × 10⁻³ L

Recall that

The mass number of MO = Mass concentration of MO × Volume of MO

The mass number of MO = (43 g/L) * (7.9 × 10⁻³ L)

The mass number of MO =  0.3397 g

number of  moles of MO = (mass number of MO) / (molar mass of MO)

number of  moles of MO = (0.3397 g) / (327.33 g/mol)

moles of MO = 0.00104 mol

The total volume = 7.9 mL + 3.13 mL + 5.49 mL + 3.43 mL

The total volume = 19.95 mL = 19.95 × 10⁻³ L

Concentration of MO [MO} =(number of moles of MO) / (total volume)

[MO] = 0.00104 mol  /  19.95 × 10⁻³ L

[MO] = 5.2130 × 10⁻⁸ M

the number of moles of H3O⁺ = molarity of HCl in the solution × the volume of HCl in solution

the number of moles of H3O⁺ = [(2.0 M) * (3.13 mL)] + [(2.0 M) * (5.49 mL)]

the number of moles of H3O⁺ = 17.24 mmol

Concentration of H3O⁺  [H3O⁺] = (the number of moles of H3O⁺) / (total volume)

Concentration of H3O⁺  [H3O⁺] = (17.24 mmol) / (19.95 mL)

Concentration of H3O⁺  [H3O⁺] = 0.864 M

The Concentration of H3O⁺  [H3O⁺] is 0.864 M

Calculation of the H3O⁺ concentration:

But before that following calculations should be needed.

The mass number of MO = Mass concentration of MO × Volume of MO

= (43 g/L) * (7.9 × 10⁻³ L)

=  0.3397 g

Now

number of  moles of MO = (mass number of MO) / (molar mass of MO)

= (0.3397 g) / (327.33 g/mol)

= 0.00104 mol

Now

The total volume = 7.9 mL + 3.13 mL + 5.49 mL + 3.43 mL

= 19.95 mL

= 19.95 × 10⁻³ L

Now

Concentration of MO [MO} =(number of moles of MO) / (total volume)

= 0.00104 mol  /  19.95 × 10⁻³ L

5.2130 × 10⁻⁸ M

Now

the number of moles of H3O⁺ = molarity of HCl in the solution × the volume of HCl in solution

= [(2.0 M) * (3.13 mL)] + [(2.0 M) * (5.49 mL)]

= 17.24 mmol

Now

Concentration of H3O⁺  [H3O⁺] = (the number of moles of H3O⁺) / (total volume)

= (17.24 mmol) / (19.95 mL)

= 0.864 M

Hence, The Concentration of H3O⁺  [H3O⁺] is 0.864 M

Answers

Answer:

C.The particles in the hot water will slow down, while the particles in the cold water will speed up

Explanation:

Heat causes changes in the molecules of substances when applied to them. The molecules of water, as a case study used in this question, when heated has an increased kinetic energy which causes its particles to move faster i.e. speed up. Also, when water is freezed or cold, it's particles move slower i.e. slow down due to decreased kinetic energy.

Hence, when a hot glass of water and a cold glass of water are placed on a kitchen table for 1 hour, they don't remain in their respective thermal state.

- The hot water (with an increased movement of molecules) begin to cool down, hence, its particles slows down as it gets cold or less hot.

- Likewise, the cold water (with a decreased movement of molecules) begins to get warmer, hence, it particles speedens up as it gets warmer.

Therefore, The particles in the hot water will slow down, while the particles in the cold water will speed up

a race car at the Daytona 500 zips around the track .its travel the first 80 kilometers in 0.4 hours. the next 114 kilometers take 0.6 . the following 80 kilometers take 0.4 hours to calculate the race car average speed.

Answers

The answer to this should be around 40

A race car at the Daytona 500 zips around the track its travel the first 80 km in 0.4 hours, the next 114km take 0.6, the following 80 km take 0.4, so the average speed is 195.71 km/hr.

How do we calculate the average speed?

Average speed of any body will be calculated by dividing the total time to cover the ditance from the total distance covered.

Total distance to cover = 80km + 114km + 80km = 274km

Total time to cover distance = 0.4hr + 0.6hr + 0.4hr = 1.4hr

Average speed of car = 274/1.4 = 195.71 km/hr

So, the average speed of car is 195.71km/hr

Explain why CaCl2 is likely to have properties similar to those of CaBr2

Answers

Answer:

Because both compounds (CaCl2 and CaBr2) contain elements (bromine and chlorine) from the same group (group 7)

Explanation:

Elements are organized into groups on the periodic table based on the number of valence electrons contained in their outermost shell. These elements in the same group i.e. same number of valence electrons, will behave in a similar manner chemically.

CaCl2 and CaBr2 are two compounds that contains elements (Chlorine and Bromine) from the same group, which is group 7. Elements in group 7 are called HALOGENS and have 7 valence electrons in their outermost shell.

Bromine (Br) and Chorine (Cl) are responsible for the similarity in the properties of CaCl2 and CaBr2 because the Chlorine and Bromine contained in them will cause them to react similarly and behave similarly in the presence of other compounds.

How many moles are in 34.0 g of dinitrogen oxide?

Answers

Answer:

0.773 mole

Explanation:

From the question given above, the following were obtained:

Mass of dinitrogen oxide (N₂O) = 34 g

Mole of N₂O =.?

Next, we shall determine the molar mass of N₂O. This can be obtained as follow:

Molar mass of N₂O = (14 × 2) + 16

= 28 + 16 = 44 g/mol

Finally, we shall determine the number of mole in 34.0 g of dinitrogen oxide (N₂O) as follow:

Mass of dinitrogen oxide (N₂O) = 34 g

Molar mass of N₂O = 44 g/mol

Mole of N₂O =.?

Mole = mass /Molar mass

Mole of N₂O = 34/44

Mole of N₂O = 0.773 mole

Therefore, 0.773 mole is present in 34 g of dinitrogen oxide

Discuss and Implement the Price Adjustment Strategies in the current market. Apply each strategy with 3 examples along with the picture. This question is related to Marketing.

Answers

Answer:

There are many different price adjustment strategies which can be implemented in the current market.

Explanation:

Psychological pricing:

Psychological pricing is a strategy in which the price of a product is displayed with mostly one cent difference so the whole number shown is less by $1 and this difference can get higher if the price of the product is more.

Example 1: The price for a toy in a toy shop is $4.99, if rounded this will be $5 but the whole number visible is $4.

Example 2: The price of a laptop is $193, this again is nearly $200 but the price is reduced by $7 in order to influence their customers into buying the product.

Example 3: The price of a car is $35,995, this again is about $36,000 but the buyer may be influenced by this technique and result in purchasing the product with such price.

Geographical Pricing:

Geographical pricing is a strategy where different prices are charged in different outlets, this strategy is made keeping in mind the purchasing power of the locality, if the local people can pay higher price for a product then the price is high there but same product may have a lower price in an area where people can not pay high price.

Example 1: Price of a T-shirt is $15 in a posh area while the price of the same T-shirt is $5 in an area with poor locality.

Example 2: Price of a hair brush is $10 in a poor area while the same brush is available in a posh area at a rate of $35.

Example 3: Price for a food item is $6 in a restaurant in posh area while the same burger is available for $3 in a restaurant in a poor area.

Alkynes are reduced to trans alkenes by a process called dissolving metal reduction. The reaction uses sodium or lithium metal as the reducing agent and liquid ammonia as the solvent. The method is specific in the formation of trans alkenes from alkynes. The method involves two successive transfers of single electrons from the alkali metal to the triple bond, with abstraction of protons from the ammonia solvent.Draw curved arrows to show the movement of electrons in this step of the mechanism.Arrow-pushing Instructions

Answers

Answer:

Explanation:

The movement of the electrons is illustrated in the picture attached to this answer. It is a four-step reaction mechanism.

First STEP: The first step involves the transfer of an electron from sodium to form a radical anion.

Second STEP: This radical anion then removes a proton/hydrogen from ammonia in a bid to neutralize itself (hence the hydrogen becomes bonded to the anion).

Third STEP: The sodium (from NaNH₂ formed) transfers an electron again to produce a vinyl carbanion.

Fourth STEP: The carbanion then removes a proton/hydrogen from ammonia (like in the second step) to form a neutral trans-alkene.

NOTE: The circled numbers denote each step while the mechanism on the left represents the use of any alkyl group (R and R') while the mechanism on the right assumes both alkyl groups are methyl. Hence, 2-butyne started the reaction and the final product was trans-2-butene.

What does 3.5 degree of unsaturation tell you?

Answers

Answer:

It means the chemical entity is a radical

Explanation:

When we talk of unsaturation, we are referring to the number of pi-bonds in a chemical entity. The alkane, alkene and alkyne organic family are used to as common examples to explain the term unsaturation.

While alkynes have 3 bonds, it must be understood that they have 2 pi bonds only and as such their degree of saturation is two.

In the case of an alkene, there is only one single pi bond and as such the degree of unsaturation is 1.

Now in this case, we have a fractional 0.5 degree of unsaturation alongside the 3 to make a total of 3.5. So what’s the issue here?

The fractional part shows that the chemical entity we are dealing with here is a radical. While the integer 3 shows that there are 3 pi-bonds, the half pi bond remaining tells us that there is a missing electron on one of the atoms involved in the chemical bonding and as such, the 1/2 extra degree of unsaturation tends to tell us this.

Kindly recall that a radical is a chemical entity within which we have at the least an unpaired electron.
