Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP. If 31.0 mL of a barium hydroxide solution are needed to neutralize 1.37 grams of KHP, what is the molarity of the barium hydroxide solution

Answers

Answer:

0.1082M of Barium Hydroxide

Explanation:

KHP reacts with Ba(OH)2 as follows:

2KHP + Ba(OH)2 → 2H2O + Ba²⁺ + 2K⁺ + 2P²⁻

Where 2 moles of KHP reacts per mole of barium hydroxide

To solve this question we must find the moles of KHP in 1.37g. With these moles and the reaction we can find the moles of Ba(OH)2 and its molarity using the volume of the solution (31.0mL = 0.0310L) as follows:

Moles KHP -Molar mass: 204.22g/mol-

1.37g * (1mol / 204.22g) = 0.006708 moles KHP

Moles Ba(OH)2:

0.006708 moles KHP * (1mol Ba(OH)2 / 2mol KHP) =

0.003354 moles Ba(OH)2

Molarity:

0.003354 moles Ba(OH)2 / 0.0310L =

0.1082M of Barium Hydroxide

a) Describe what happens to the first spoonful of powder when he mixes it with the acid.
b) Describe what would happen if the student kept adding zinc oxide to the nitric acid
after the reaction between the acid and metal oxide was complete.

Answers

Answer:

See Explanation

Explanation:

The equation of the reaction is;

ZnO(s) + 2HNO3(aq) --------> Zn(NO3)2(aq) + H2O(l)

a) When you first add ZnO to aqueous HNO3, the powder dissolves as it mixes with the acid.

b) If the student keeps on adding more ZnO powder to the HNO3 after the  reaction between the acid and metal oxide was complete, the powder will no longer dissolve in the acid. At this point, the reaction has attained equilibrium.

Answers

Answer:

D.Meat

Explanation:

Meat-Most animals proteins are considered complete and high-quality.This includes red meat, poultry,and dairy products.

Amino acids are the molecules that make the protein and are essential nutrients. Meat is the best source that will have amino acids. Thus, option D is correct.

What are amino acids and proteins?

Amino acids are the building blocks that make the macromolecule, a protein required for functioning, strength, and activities of the body. Amino acid-containing foods like eggs, meat, and soybeans are rich in proteins.

Amino acids and proteins are essential for body growth and repair that can be gained from poultry sources like eggs, meat, fish, cheese, quinoa, beans, etc. Bread, fruits, and butter are rich in carbohydrates.

When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(II) sulfate PbSO4 is reduced to lead at the cathode and oxidized to solid lead(II) oxide PbO at the anode. Suppose a current of 17.0A is fed into a car battery for 15.0 seconds. Calculate the mass of lead deposited on the cathode of the battery. Be sure your answer has a unit symbol and the correct number of significant digits.

Answers

Answer:

0.273504 grams

Explanation:

Charge Deposited = Current ×Time

q=It

Given: I= 17.0A, t= 15.0 seconds

Q= 17×15= 255 C

Since, 1 mole contains 96500C of charge deposition

Therefore, number of moles = 255/96500 = 0.00264 moles

Moreover, since Pb changes to Pb2+,

Hence number of moles of Pb deposited = 0.00264/2

= 0.00132

Also, Molar mass of Lead = 207.2 gm/mol

Therefore, the mass of lead deposited = 0.00132×207.2 = 0.273504 grams

Submit Answer

Answers

Answer:

2. Hydrogen Bonds

Explanation:

Since water is a polar covalent molecule, there is a slight negative and positive end. Due to this, the oxygen end of one water molecule gravitates towards the hydrogen molecules of another water molecule. This accounts for a bunch of weird properties of water, like why ice floats. It's also what makes water the "universal solvent," and gives all life on earth the ability to even exist.

The primary forces of attraction between water molecules in H₂O (I) are hydrogen bonds.

What kind of chemical bonding is present in water molecule?

Hydrogen bonding is present in water molecule due to which it exhibits an excellent property of adhesion to itself and to other substances.The hydrogen bonding is a result of electrostatic forces of attraction which are generated by the difference in charge between slightly positive hydrogen ions and slightly negative other ions.

In case of water,hydrogen bonds are formed  between neighboring  hydrogen and oxygen atoms  of the nearby water molecules.The attraction between water molecules itself results in a formation of a bond called as a hydrogen bond.  

It is a type of covalent bond which is formed  between hydrogen and oxygen atoms as one oxygen atom  shares its two electrons with two hydrogen atoms .The positive charge  of one hydrogen atom associates with negative charge of  oxygen atom.These are weak interactions  which are formed between a hydrogen atom each with a partial positive charge and an oxygen atom which is more electronegative than hydrogen.

Suppose Gabor, a scuba diver, is at a depth of 15m15m. Assume that: The air pressure in his air tract is the same as the net water pressure at this depth. This prevents water from coming in through his nose. The temperature of the air is constant (body temperature). The air acts as an ideal gas. Salt water has an average density of around 1.03 g/cm3g/cm3, which translates to an increase in pressure of 1.00 atmatm for every 10.0 mm of depth below the surface. Therefore, for example, at 10.0 mm, the net pressure is 2.00 atmatm. What is the ratio of the molar concentration of gases in Gabor's lungs at the depth of 15 meters to that at the surface

Answers

Answer:

The ration of molar concentration is "2.5".

Explanation:

The given values are:

Average density of salt water,

= [tex]1.03 \ g/cm^3[/tex]

Net pressure,

= [tex]2.00 \ atm[/tex]

Increase in pressure,

= [tex]1.00 \ atm[/tex]

Now,

The under water pressure will be:

=  [tex]\frac{15 \ m}{10}\times 1 \ atm +1 \ atm[/tex]

=  [tex]1.5\times 1+1[/tex]

=  [tex]1.5+1[/tex]

=  [tex]2.5 \ atm[/tex]

hence,

The ratio will be:

=  [tex]\frac{(\frac{n}{V})_{15m} }{(\frac{n}{V})_{surface} }[/tex]

or,

=  [tex]\frac{P}{P_s}[/tex]

=  [tex]\frac{2.5}{1}[/tex]

=  [tex]2.5[/tex]

For 2-methylbutane, the AH° of vaporization is 25.22 kJ/mol and the

AS° of vaporization is 84.48 J/mol K. At 1.00 atm and 201 K, what is

the AG° of vaporization for 2-methylbutane, in kJ/mol?

Answers

Answer:

ΔG° = ΔH° - TΔS°

ΔG° = 25.22-(201 )(0.08448)

ΔG° = 8.24 kJ/mol

The standard free energy is obtained as 8.2  kJ/mol.

We know that; ΔG° = ΔH° - TΔS° where;

ΔG° = standard free energy

ΔH° = standard enthalpy

T = temperature

ΔS° = standard entropy

Hence substituting the values;

ΔG° =25.22 kJ/mol - (201 K * 84.48 J/mol K)

ΔG° = 25.22 * 10^3 J/mol -   16980.5 J/mol

ΔG° = 8.2  kJ/mol

The correct answer is option D: Reeling​.

Wool is obtained from sheep. The wool so obtained is processed according to the following flow chart;

Shearing → Scouring → Sorting → Dyeing → Straightening, Rolling and Combing

Shearing is the removal of the fleece and thin skin of the sheep. Scouring is the process of washing the hair to remove grease, dust, and dirt. Sorting is the process of differentiating the fibers.
