Answers

Answer 1

Chelating agents are used to: add color to foods, prevent discoloration, maintain emulsions, whiten foods such as cheese, improve nutritional value. All of the given options are correct.

Chelating agents are substances that have the ability to form a complex with a metal ion, holding it in a stable and soluble form. This property makes chelating agents useful in a variety of applications, including food processing and preservation.

One of the main uses of chelating agents in the food industry is to prevent discoloration. Metal ions, such as iron and copper, can cause discoloration in foods by catalyzing oxidative reactions. By forming stable complexes with these metal ions, chelating agents can prevent discoloration and maintain the color of the food.

Chelating agents are also used to maintain emulsions. Emulsions are mixtures of immiscible liquids, such as oil and water, which are held together by a stabilizing agent. Metal ions can disrupt the stability of an emulsion by catalyzing the breakdown of the stabilizing agent. Chelating agents can form complexes with metal ions, preventing them from catalyzing the breakdown of the emulsion.

Chelating agents are also used to whiten foods such as cheese. Metal ions can cause discoloration in cheese, and chelating agents can prevent this discoloration by forming complexes with the metal ions.

Finally, chelating agents can improve the nutritional value of foods by increasing the bioavailability of certain minerals. For example, chelating agents can form complexes with iron, making it more readily absorbed by the body.

Overall, chelating agents are an important class of compounds with a variety of uses in the food industry. Their ability to form stable complexes with metal ions makes them useful in preventing discoloration, maintaining emulsions, and improving the nutritional value of foods. Hence, all of the given options are correct.

A sample of hydrogen gas collected at a pressure of 0.923 atm and a
temperature of 17.0 °C is found to occupy a volume of 29.6 liters. How many
moles of H₂ gas are in the sample?
mol

Answers

Answer:

1.15 moles H₂

Explanation:

To find the moles of H₂ gas, you need to use the Ideal Gas Law equation. The equation looks like this:

PV = nRT

In this equation,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = moles

-----> R = Ideal Gas Constant (0.08206 L*atm/mol*K)

-----> T = temperature (K)

Before you can plug the given values into the equation and simplify, you need to convert Celsius to Kelvin.

P = 0.923 atm                     R = 0.08206 L*atm/mol*K

V = 29.6 L                           T = 17.0 °C + 273.15 = 290.15 K

n = ? moles

PV = nRT

(0.923 atm)(29.6 L) = n(0.08206 L*atm/mol*K)(290.15 K)

27.3208 = n(23.809709)

1.15 = n

Two liquids are in a graduated cylinder - liquid a has a density of 1.004 g/cm3 and liquid b has a density of 0.6223 g/cm3 . assuming that they do not mix, which liquid is on top and which liquid is on bottom? where would you expect to find the plastic cube from question #2 if it is dropped into the graduated cylinder with these two liquids?

Answers

Liquid B is expected to be at the top while liquid A is found at the bottom.

What is density?

The term density has to do with the ratio of the mass of a substance to its volume. Now given that the density of a substance actually shows how much heavy the substance is, it is not difficult to understand that a material that has a low density will flat at the top of a material that has a lower density.

Here we are told that the two liquids do not mix. If they do not mix then it follows that they must have formed a two phase system in which one is at the top of the other. The one that is at the top must have the lower density.

Thus, liquid B is expected to be at the top while liquid A is found at the bottom. From the density of the plastic cue, the cube will be at the top.

What is a Racemic mixture?

An equimolar mixture of two enantiomers that is optically inactive is known as a racemic mixture (or racemate) (i.e. does not rotate plane-polarized light).

The racemic mixture can be created by:

Combining enantiomers in equal amounts, or (more frequently) Reactions that create one or more new chiral centers without the influence of chirality (i.e. chiral reagent, catalyst, etc.)

The light that is plane-polarized does not spin in an optically inactive mixture.

In the combustion of propane: __ C3H8 __ O2 --> __ CO2 __ H2O When the equation is balanced using the smallest whole numbers, the coefficient of O2 will be:

Answers

Answer:

1 C3H8 + 5 O2 --> 3 CO2 + 4 H2O

Explanation:

USE PENCIL!  Balancing equations typically requires some initial trial and error.  Making changes is common.

_ C3H8 __ O2 --> __ CO2 __ H2O

We know we can only have whole molecules, so all number coefficients must be, eventually, whole numbers.  It is OK to start with a fraction, but the final must be a shole number.  Pick the most complex molecule (either product or reactant) and assign it a coefficient of 1.

1 C3H8 __ O2 --> __ CO2 __ H2O

Now find places for each of the atoms in C3H8 on the product side.  3 carbons means we need 3CO2 molecules, so add a coeffient of 3,

1 C3H8 __ O2 --> 3 CO2 __ H2O

3 CO2 means we need 6 oxygens, so add a coefficient of 3 for the O2:

1 C3H8 + 3 O2 --> 3 CO2 __ H2O

Now find a home for the 8 hydrogens that come from the 1 C3H8.  Add 4 to the H2O product:

1 C3H8 + 3 O2 --> 3 CO2 + 4 H2O

This last step added 4 more O to the product side, so we need to adjust the reactant source of O:

1 C3H8 + 5 O2 --> 3 CO2 + 4 H2O

Double check the result:

Element   Reactant  Product

 C                   3              3

 H                   8              8

 O                  10             10(6+4)

Everything checks.

[Note that one might use a fraction such as 1/2 or 1/3 just to make the balance work.  But fractions must be converted to whole numbers for the final equation.  For 1/2, multiply all coefficients by 2.  By 3 for 1/3, etc.]

The given question deals with Analytical Chemistry where Concentration is asked here.

Concentration: Generally concentration is defined as amount of the substance per unit volume. Concentration is also expressed in parts per million(ppm) when it is a small quantity as in case of mercury content in fish.

Explanation:   Given mass of the fish = 250 g,

                         ppm = 0.23

               Now mass of mercury = 0.23 ppm × 250 g                                                        

                                                     = 0.23/1,000,000 × 250g

                                                    =0.23×250/1,000,000 g

As a reaction proceeds toward equilibrium from reactants to products, the value of Q is Increasing

Equilibrium can exist in chemical processes (the products and reactants are produced at the same rate). In a reversible chemical reaction, chemical equilibrium is the state in which there is no net change in the quantity of reactants or products. When a chemical reaction is reversible, the products react with the original reactants as soon as they are created.

There is no net change in the quantity of the chemicals involved when the two opposing reactions are in equilibrium because they are occurring at identical rates, or velocities. At this point, the reaction may be deemed to be finished, meaning that the maximum amount of reactants to products has been converted under the given reaction conditions.

Answers

The molecular formula of dye:

A major textile dye manufacturer developed a new yellow dye with a molecular formula [tex]C_{15}N_{3}H_{15}[/tex].

Given:

Percentage composition:

C = 75.95%

N = 17.72%

H = 6.33%

Molar mass = 240 g

To find: molecular formula of dye

Calculation:

Let's assume the mass of the compound is 100 gm.

So,  Mass of C = 75.95 gm

Mass of N = 17.72 gm

Mass of H = 6.33 gm

The number of moles = given mass/mass

Therefore, the number of moles of C = 75.95/12 = 6.33

The number of moles of N = 17.72/14 = 1.27

Number of moles of H =6.33/1 = 6.33

Simplest ratio:

C = 6.33/1.27 = 4.98 =5

N = 1.27/1.27 = 1

H = 6.33/1.27 = 4.98 =5

Therefore, the empirical formula is [tex]C_{5}NH_{5}[/tex]

The mass of empirical formula = 12 x 5 + 14 + 1 x 5 = 79 gm

Number of moles= molar mass/ empirical formula

n = 240/79 = 3.04 =3

Therefore, molecular formula = empirical formula x n

Pyridinium chlorochromate [PCC] converts primary OH to aldehydes, whereas it converts secondary OH to ketones, and oxidation of tertiary OH has little effect. Alcohols and pyridinium chlorochromate [PCC] react to create a carbonyl molecule.

From primary alcohols to aldehydes and from secondary alcohols to ketones, pyridinium chlorochromate oxidizes alcohols one step up the oxidation ladder. pyridinium chlorochromate will not oxidize aldehydes to carboxylic acids, in contrast to chromic acid.
