Find the volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide.

Answers

Answer 1

The volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide is 0.15L

The reaction of sulphuric acid and sodium hydroxide is expressed as:

[tex]2NaOH + H_2SO_4 ==> Na_2SO_4 + 2H_2O[/tex]

Determine the moles of NaOH present

Molar mass of NaOH = 23 + 16 + 1 = 40g/mole

Given that mass of NaOH is 75.0g

Mole of NaOH = 75/40  = 1.875moles

Determine the number of moles [tex]H_2SO_4[/tex] needed to react with 1.875 moles NaOH

Moles of [tex]H_2SO_4[/tex] = [tex]\frac{1.875}{2} = 0.9375moles of H_2SO_4[/tex]

Recall that volume = Molar mass * number of moles

Volume of [tex]H_2SO_4[/tex] =  0.160 * 0.9375

Volume of  [tex]H_2SO_4[/tex] = 0.15L

Hence the volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide is 0.15L

Suppose you are performing a titration. At the beginning of the titration, you read the titrant volume as 2.51 mL. After running the titration and reaching the endpoint, you read the titrant volume as 29.95 mL. What volume, in mL, of titrant was required for the titration

Answers

The volume of titrant required for the titration would be 27.44 mL

From the illustration, the initial titrant volume was 2.51 mL. This figure represents the initial reading on the burette.

In the same vein, the final volume of the titrant was 29.95 mL. This figure represents the final reading on the burette.

In order to get the volume of titrant used:

Volume of titrant used = final volume - initial volume

                             = 29.95 - 2.51

                                = 27.44 mL

How many moles of NH3 can be produced from 5.50 moles of nitrogen in the following reaction: N2+3H2=2NH3

Answers

Answer:

Explanation:

Let the molar balance numbers be your guide.

N2 has  a one in  front of  it.

2 NH3 has a two in front of it.

Nitrogen has 5.50 moles given.

1 / 5.50 = 2 / x                 Cross multiply

1 x  = 2 * 5.50

x = 11.0

So if you use 5.5 moles of nitrogen, you get 11 moles of NH3

Calculate the mass of 5.3 moles of chloric acid (HClO3). Explain the process or show your work by including all values used to determine the answer.

Answers

Answer:

447.64 grams

Explanation:

To find the mass when given moles, it is a pretty simple process.

I start by finding the molar mass of chloric acid, which comes out to 84.46 grams/mol. To find the MM (molar mass), you just take the mass of each element in the molecule from the periodic table and add them all together.

After this, you set up the equation by taking the moles given and multiplying it by the molar mass. This gives you the new value in grams (since we cancelled out the moles). I have attached my work below.

I hope this helps! :^)

The mass of 5.3 moles chloric acid has been 447.85 g.

The mass of 1 mole of a compound has been equivalent to the molar mass of the compound. The molar mass of a compound has been the sum of the constituent atoms in a formula unit.

The molar mass (mwt) of chloric acid has been given as:

[tex]mwt=m_H\;+\;m_C_l\;+\;(m_O\;\times\;3)[/tex]

By substituting the values for the mass of constituent atoms, the molar mass has been given as:

[tex]mwt=1\;+\;35.5\;+\;16\;\times\;3\\mwt=36.5\;+\;48\\mwt=84.5[/tex]

The molar mass of chloric acid has been 84.5 g/mol.

The mass of 1 mole of chloric acid has been 84.5 g/mol. The mass of 5.3 moles chloric acid has been:

[tex]\rm 1\;mol=84.5\;g\\5.3\;mol=5.3\;\times\;84.5\;g\\5.3\;mol=447.85\;g[/tex]

The mass of 5.3 moles chloric acid has been 447.85 g.

Recreational drug users often obtain the drug as a white powder with unknown purity. Some users snort the power, whereas others make a solution and take it orally or inject it. To achieve a ketamine high, users usually need to take between 0.1 mg/kg and 1 mg/kg of ketamine. However, taking 2 mg/kg can lead the user to experience a K-hole or to enter an unconscious state.

If the user dissolves exactly 1 g of ketamine in 1/4 cup of water, what is the concentration of ketamine in milligrams per milliliter (mg/mL)? 1 cup=236.5 mL
What volume, in milliliters, of the recreational ketamine in the previous question would a 59.0 kg user need to take to experience a high at 0.600 mg/kg?
How many milliliters would that same user need to take to become unconscious at 2.00 mg/kg?

Answers

If a user dissolves exactly 1 g of ketamine in 1/4 cup of water, the resulting concentration is 16.91 mg/mL. A 59.0 kg user would have to consume 2.09 mL of this solution to experience a high of 0.600 mg/kg. The same user would have to consume 6.98 mL of this solution to become unconscious at 2.00 mg/kg.

Part 1

A user dissolves exactly 1 g of ketamine in 1/4 cup of water.

Given 1 cup = 236.5 mL, the volume of 1/4 cup of water is:

1/4 cup × (236.5 mL/1 cup) = 59.13 mL

1 g of ketamine is dissolved in 59.13 mL of water. The concentration of ketamine, in mg/mL, is:

C = 1000 mg / 59.13 mL = 16.91 mg/mL

Part 2

The volume of this solution that a 59.0 kg user (body mass) would have to consume to experience a high at 0.600 mg/Kg is:

[tex]59.0 kgBM \times \frac{0.600mgKetamine}{1kgBM} \times \frac{1mL Soluiton}{16.91mgKetamine} = 2.09 mL[/tex]

Part 3

The volume of this solution that a 59.0 kg user (body mass) would have to consume to become unconscious at 2.00 mg/kg is:

[tex]59.0 kgBM \times \frac{2.00mgKetamine}{1kgBM} \times \frac{1mL Soluiton}{16.91mgKetamine} = 6.98 mL[/tex]

If a user dissolves exactly 1 g of ketamine in 1/4 cup of water, the resulting concentration is 16.91 mg/mL. A 59.0 kg user would have to consume 2.09 mL of this solution to experience a high of 0.600 mg/kg. The same user would have to consume 6.98 mL of this solution to become unconscious at 2.00 mg/kg.

Describe how you could adjust the settings of the simulation to increase the number of red (H3O+) and blue (A-) particles in the solution of equilibrium. In three to four sentences, justify your answer and explain how and why this would change the pH of the solution.

Answers

The addition of more acid or base will increase the number of H3O+ and A- particles thereby decreasing and increasing the pH of the solution respectively.

What is an acid-base titration?

An acid-base titration is one in which an acid is added to a given volume of base in order to neutralize it.

When more of acid is added to a solution of a base than is required to neutralize it, the solution becomes acidic.

Similarly, when more base is use to neutralize an acid than is required, the solution becomes alkaline.

In the given simulation, (H3O+) is the acid while (A-) is the base.

By adding increasing the quantity of acid added, the number of H3O+ particles will increase. This will reduce the pH of the solution.

Also, the adding more base to the solution, the number of A- particles in the solution will increase. This will increase the pH of the solution.

Therefore, addition of more acid or base will increase the number of H3O+ and A- particles thereby decreasing and increasing the pH of the solution respectively.

An unknown hydrocarbon compound was analyzed for hydrogen by elemental analysis and results show that it contains 15.88 % H. What is the empirical formula

Answers

Answer:

C4H9

Explanation:

If H = 15.88%

Then C = 100.00 – 15.88 = 84.12

Divide each % value by respective atomic mass

H = 15.88/1 = 15.88

C = 84.12/12 = 7.01

Divide through by smaller value

H = 15.88/7.01 = 2.26

C = 7.01/7.01 = 1

Remove fraction , multiply by 4

H = 9

C = 4

Empirical formula = C4H9

The hydrocarbon could be ( C4H9)2 = C8H18 = octane.

a peanut butter and jelly sandwich contains 9.00 g of fat, 6.00 g of protein, and 25.0 g of carbohydrate. How many calories does this sandwich provide?

Answers

Answer:

205 calories.

Explanation:

According to the USDA, "Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram." 9 grams of fat at 9 calories per equals 81 calories + 6 grams of protein at 4 calories per gram which equals 24 calories + 25 grams of carbohydrate at 4 calories per gram which is equal to 100 calories.

Total that all up and you get 81 cal + 24 cal + 100 cal=205 calories.

I don't know what kind of course this is for, but if they are incredibly picky, what we refer to as "calories" are actually kilocalories, which are equal to one thousand "real" calories each. However, I'm very confident that the correct answer is 205 calories.

The sandwich will provide 205 calories.

What is calories?

A calorie is an energy unit. It's the quantity of heat needed to increase the temperature of one gramme of water by [tex]1^{0} C[/tex] at one atmosphere of pressure.

Its is given that, Fat = 9 g, protein = 6 g, carbohydrate = 25 g.

It is known that, fat contains 9 calories / gram , carbohydrate contains 4 calories / gram and protein contains 4 calories / gram.

Now, adding all terms.

Total calories = (9×9) +(6×4) +(25×4)

= 205 calories.

Therefore, the sandwich will provide a total of 205 calories.

Answers

2.89 moles of water would be produced by the complete combustion of 44.5 grams of ethanol in the presence of excess oxygen.

According to this question, the following reaction between ethanol and oxygen is given:

C₂H₆O(l) + O₂(g) → CO₂(g) + H₂O(l)

However, this equation is not balanced. The balanced equation is as follows:

C₂H₆O + 3O₂ → 2CO₂ + 3H₂O

According to this equation, 1 mole of ethanol produces 3 moles of water.

We convert 44.5g of ethanol to moles by dividing by its molar mass as follows:

mole = 44.5g ÷ 46.07g/mol

mole = 0.966mol of ethanol

If 1 mole of ethanol produces 3 moles of water.0.966mol of ethanol will produce (0.966 × 3) = 2.89mol

Therefore, 2.89 moles of water would be produced by the complete combustion of 44.5 grams of ethanol in the presence of excess oxygen.
