. saccharin (c7h5no3s) is sometimes dispensed in tablet form. ten tablets with a total mass of 0.5894 g were dissolved in water. this solution was then oxidized to convert all the sulfur to sulfate ion, which was precipitated by adding an excess of barium chloride solution. the mass of baso4 obtained was 0.5032 g. what is the average mass of saccharin per tablet? what is the average mass percent of saccharin in the tablets?

Answers

Answer 1

The moles are literally the molar mass of a solute and has the moles of solute and solvent of this solution as the average mass percent of saccharin in the tablets is 69%.

The sulfur (S) is oxidized to sulfate ions (SO₄²⁻). All the SO₄²⁻ ions are brought about with BaCl₂ answer withinside the shape of BaSO₄ (s).

The response is as follows-

BaCl₂ (aq) + SO₄²⁻ (aq) → BaSO₄ (s) + 2Cl⁻So, this shows that after 1 mol of Saccharin (C₇H₅NO₃S) is dissolved, then 1 mol of BaSO₄ is brought about.The quantity of moles of C₇H₅NO₃S is same to the quantity of moles of BaSO₄.The quantity of moles of BaSO₄ = (mass of BaSO₄ obtained) / (molecular mass of BaSO₄) = (0.5032 g) / (233.39 g/mol) = 0.0022 molesSo, The quantity of moles of C₇H₅NO₃S = 0.0022 molesMass of Saccharin (C₇H₅NO₃S) = (quantity of moles of C₇H₅NO₃S) × (molecular mass of C₇H₅NO₃S) = (0.0022 moles) × (183.18 g/mol) = 0.403 gThe common mass percent of Saccharin (C₇H₅NO₃S) in drugs may be decided by-[(mass of C₇H₅NO₃S) / (mass of tablets)] × 100 % = [ (0.403 g) / (0.5894 g) ] × 100 % = 68.37 %68.37n be rounded off as 69 %So, the common mass percent of Saccharin (C₇H₅NO₃S) in drugs is 69 %.

a solution is prepared at that is initially in propanoic acid , a weak acid with , and in potassium propanoate . calculate the ph of the solution. round your answer to decimal places

Answers

The pH of the solution is 4.16.

What is pH?

pH is a numerical indicator of how acidic or basic aqueous or other liquid solutions are. The phrase, which is frequently used in chemistry, biology, and agronomy, converts the hydrogen ion concentration, which typically ranges between 1 and 10⁻¹⁴ gram-equivalents per liter, into numbers between 0 and 14.

Given,

Concentration of propanoic acid = 0.45 M

Concentration of potassium salt = 0.086 M

Now, Kₐ of propanoic acid = 1.3 × 10⁻⁵

∴ pKₙ = -log (1.3 × 10⁻⁵)

= 4.886

Using Henderson-Hasselbalch equation

pH = pKₐ + log [salt]/[acid]

= 4.886 + log(0.086)/(0.45)

=4.16

pH= 4.16.

What is enthalpy of reaction?

Enthalpy of reaction (also known as the heat of reaction) is the amount of heat released or absorbed during a chemical reaction. It is an important physical property of a reaction, and is a measure of the reaction’s ability to do work. It is related to the change in internal energy of a reaction and can be calculated using Hess’s law. Enthalpy of reaction can be used to calculate the temperature of the reaction, the rate of reaction, and the amount of energy released or absorbed in the reaction. It is also used to determine the equilibrium constants for a reaction, and can be used to predict the stability of a reaction. Enthalpy of reaction is an important concept in thermodynamics and can be used to study the energetics of a reaction.

The enthalpy per mole of reactant is expressed in units of kj/mol.

(0.434 g of Na) × (1 mole Na / 22.990g) = 0.0189 mole

ΔH= -4.510kj /0.0189 mole = - 238.62 Kj/ mol

in the laboratory you dilute 2.29 ml of a concentrated 6.00 m hydrochloric acid solution to a total volume of 100 ml. what is the concentration of the dilute solution?

Answers

The concentration of the diluted solution will be 0.13 M

It asks you to find the concentration, which is the safe to assume that the unit is Molarity (M). Also, the  unit was used in  the problem as well.

Molarity has the  units of moles/L so we have to work on getting to this point.

The problem states that you have the  2.29 mL of a 6.00 M concentration. First, we will need moles. To get the  moles, we use stoichiometry,

2.29 mL = 0.00229 L

0.00229 L x ( 6 moles/ L) = 0.01374 moles

0.00229 L x ( 6 moles/ L) = 0.01374 moles

This is how many moles are present inside the solution.

To find the new concentration, we divide the total number of moles by the new volume in the Liters:

0.01374 moles/0.100L = 0.1374 M

Rounding to two significant figures, we get 0.13 M.

The molarity of H2SO4 when a 20.00 ml volume of h2so4 solution is titrated with 0.125 m NaOH. the initial volume of NaOH in the buret is 0.75 ml and the final volume is 42.35 ml is 0.260 M.

The balanced equation is  2NaOH+H2SO4→Na2SO4+2H2O.

The formula to calculate molarity is

c=n/v

n= c×v

Where, n = moles v= volume and c= molarity

So, the moles in NaOH

nNaOH = 0.125 × 0.75/ 1000

             = 9.3 × 10^-3

From the equation we can see that number of moles of H2SO4 must be half that amount so:

nH2SO4 = 9.3 × 10^-3 /2

               =4.65 × 10^-3

c = n/v

[H2SO4] = 4.65 × 10^-3 /20× 10^-3

Answers

The percent yield of the solution is 17.7% that can be calculated by using experimental and theoretical yield.

Moles of silver nitrate = 305/169.87 = 1.8 moles.

Therefore the 1.8 moles of AgNO₃ and excess of MgCl will give 0.9 mole of MgNO₃.

Percent yield can be calculated by dividing the actual yield by the theoretical yield multiplied by 100.

Theoretical yield = 0.9 x 148.3= 133.47

select the intermolecular force that is overcome when hexane is converted from a liquid to a gas.

Answers

Electrostatic in nature, intermolecular forces result from the interaction of positively and negatively charged entities. Intermolecular interactions are the total of both attracting and repulsive elements, similar to covalent and ionic connections.

What characteristics do intermolecular forces have?

forces of attraction between molecules

Although much less than intramolecular forces of attraction, intermolecular forces play a crucial role in determining the physical characteristics of molecules, including their melting and boiling points, density, and enthalpies of fusion and vaporization.

What determines whether a reaction is intermolecular?

It can be helpful to distinguish between intramolecular and intermolecular processes. While two or more reaction sites within the same molecule are engaged in intramolecular reactions, covalency changes occur in two distinct molecules during intermolecular reactions.

If the temperature of a fixed amount of an ideal gas is increased, it necessarily follows that: ________

Answers

If the temperature of a fixed amount of an ideal gas is increased, it necessarily follows that: the average speed of the gas molecules will increase.

What is an ideal gas?

Multiple randomly moving point particles with no interparticle interactions make create an ideal gas in a theory. The ideal gas notion is useful because it complies with the ideal gas law, has condensed equation of state, and can be studied using statistical mechanics. If, for an instance, the interaction is totally elastic or is thought of as point-like collisions, the constraint of zero interaction can frequently be disregarded.

Many real gases behave qualitatively like an ideal gas under varied temperature and pressure settings, where the gas molecules (or atoms for monatomic gases) take the place of the ideal particles.

If specific properties are preserved within appropriate bounds over a wide range of temperatures and pressures, many gases, including nitrogen, oxygen, hydrogen, noble gases, some heavier gases like carbon dioxide, and mixtures like air, can be categorized as ideal gases. At higher temperatures and lower pressures, a gas typically behaves more like an ideal gas because the potential energy from intermolecular forces is less significant compared to the kinetic energy of the particles and the size of the molecules is less significant compared to the void space between them.

If the bond angle between two adjacent hybrid orbitals is 109.5°, which is the hybridization?
a. Sp2
b. Sp3d
c. Sp3
d. Sp

Answers

If the bond angle between two adjacent hybrid orbitals is 109.5°, the hybridization is sp³. ore about

The hybridization is sp³ for the  bond angle between two adjacent hybrid orbitals is 109.5°. the electrons groups are involved in this process. the four orbitals involves in the sp³ hybridization , the one s orbital and the p orbitals are involve and the hybrid orbital is formed is as sp³ hybridization. the geometry is tetrahedral. the example of the  sp³ is the methane.

Thus, for the sp³  hybridization  the  bond angle between two adjacent hybrid orbitals is 109.5° and the geometry is tetrahedral.
