I. Three Different Representations Of Glucose Aregiven Below. Identify Each Typeof Model.
Answer 2

The three structures of glucose represent three different models, they are ball and stick model, Fischer projection and bond line notation, respectively.

Glucose is a type of simple sugar (carbohydrate) that does not further hydrolyze to give monosaccharides.

Ball and stick model: The atoms are portrayed as different colored balls connected to each other by "sticks." Fischer projection: The atoms on the sides of the plane are coming out of the plane, while the atoms at the ends are moving behind.Bond line notation: It is the most frequent representation method used; it lacks C and H bonds but instead depicts carbons through bends.

Therefore, the three glucose structures reflect three distinct models: the ball and stick model, the Fischer projection, and the bond line notation, respectively.

Determine the volume (L) of nitrogen monoxide gas that is created at STP when 32.2 g

of solid copper reacts with excess nitric acid.

3Cu(s) + 8HNO3(aq) — 3Cu(NO3)2 (aq) + 4H2O(1) + 2NO(g)

Answers

Taking into account the reaction stoichiometry and STP conditions, the volume of nitrogen monoxide gas that is created at STP when 32.2 g of solid copper reacts with excess nitric acid is 7.5677 L.

Reaction stoichiometry

The balanced reaction is:

3 Cu(s) + 8 HNO₃(aq) → 3 Cu(NO₃)₂ (aq) + 4 H₂O(l) + 2 NO(g)

By reaction stoichiometry, the following amounts of moles of each compound participate in the reaction:

Cu: 3 molesHNO₃: 8 molesCu(NO₃)₂: 3 molesH₂O: 4 moles NO: 2 moles

The molar mass of the compounds is:

Cu: 63.54 g/moleHNO₃: 63 g/moleCu(NO₃)₂: 187.54 g/moleH₂O: 18 g/moleNO: 30 g/mole

By reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

Cu: 3 moles× 63.54 g/mole= 190.62 gramsHNO₃: 8 moles× 63 g/mole= 504 gramsCu(NO₃)₂: 3 moles ×187.54 g/mole= 562.62 gramsH₂O: 4 moles ×18 g/mole= 72 gramsNO: 2 moles ×30 g/mole= 60 grams

STP conditions

The STP conditions refer to the standard temperature and pressure, which values are 0 °C and 1 atmosphere and are reference values for gases. In these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

Moles of NO formed

The following rule of three can be applied: if by reaction stoichiometry 190.62 grams of Cu form 2 moles of NO, 32.2 grams of Cu form how many moles of NO?

moles of NO= (32.2 grams of Cu× 2 moles of NO)÷ 190.62 grams of Cu

moles of NO= 0.3378 moles

Then, 0.3378 moles of NO are formed.

Volume of NO created

Now, you can apply the following rule of three: if by definition of STP conditions 1 mole of NO occupies a volume of 22.4 liters, 0.3378 moles occupies how much volume?

volume= (0.3378 moles× 22.4 L)÷ 1 mole

volume= 7.5677 L

Finally, the volume of NO created is 7.5677 L.

Explanation:

D is the correct answer due to the fact that they way they are connected has 2 purple atoms and 1 orange one. thus would create a 1:2 ratio with 1 orange atom and 2 purple atoms.

A would create a 2:3 ratio, B wouldn't create a ratio comparable to the others, and C creates a 1:1 ratio with a few purple atoms floating around them, making all of the answers except D invalid.

In the given figures, the name of the model representing a compound with a 1:2 is figure D.

What is molar ratio?

Molar ration of any compound gives idea about the ratio of the concentration of given constituents present in that compound.

In the figure A molar ratio is 2:3, in figure B molar ratio of given constituents is not given because each molecule is composed of same types of atoms, in figure C molar ratio of given constitutes particles is 1:1 and in the figure D molar ratio of constituents is 1:2. Because in figure D, two atoms of one element and 1 atom of another element is present.

Hence, figure D is correct option.

Answers

Answer:

I think B) electronegativity is the correct answer.

Electronegativity is the property which is  used to determine the degree of polarity between two bonded atoms. Therefore, the correct option is option B.

What is polarity?

Polarity is the dispersion of electrical charge over the atoms linked by a chemical bond. Bonds between identical atoms, such as H2, are electrically homogeneous in the sense that both hydrogen atoms are electrically neutral, but bonds between different atoms are electrically inequivalent.

Electronegativity is the property which is  used to determine the degree of polarity between two bonded atoms. The relative electronegativities of the elements determine the polarity of a bond. Electronegativity is the ability of an element's atom to attract electrons to itself when it is part of a compound.

Therefore, the correct option is option B.

What is the volume of HCl (r= 1.17 g / cm ^ 3, omega = 36 \%) required to precipitate silver in the form of AgCl from 2, 000 g of an alloy containing 22% by weight of Ag, if used 1.5 times the amount of precipitating reagent?​

Answers

The volume of precipitating reagent, HCl required to precipitate silver in the form of AgCl from 2,000 g of an alloy containing 22% by weight of Ag is 0.530 L

In order to determine the volume of precipitating reagent, HCl required to precipitate silver in the form of AgCl from 2,000 g of an alloy containing 22% by weight of Ag, the following steps are followed:

Step 1.

The concentration of the HCl solution is calculated using the formula:

Molarity = percentage * specific gravity * 1000 cm³ / molar mass * 1 L

Percentage purity of HCl = 36% = 0.36

specific gravity, r = 1.17 g/cm³

molar mass of HCl = 36.5 g/mol

Concentration of HCl = 0.36 * 1.17 * 1000 / 36.5 * 1

Concentration of HCl = 11.53 mol/L

Therefore, 1 L of HCl solution contains 11.53 moles of HCl

Step 2:

The equation of the dissociation of HCl solution is given below:

HCl (aq) ------> H⁺ (aq) + Cl⁻ (aq)

1 mole of HCl produces 1 mole of Chloride ions, Cl⁻

Equation of reaction between Silver in the alloy and HCl is given as follows:

Ag (s) + H⁺Cl⁺ (aq) -----> AgCl (s)

A white precipitate of AgCl is formed but hydrogen gas is not formed as Silver is a less reactive metal.

1 mole of HCl produces 1 mole of Cl⁻ which reacts with 1 mole of Ag to produce 1 mole of AgCl precipitate.

Step 3: Determine the mass and number of moles of silver in the alloy

Percentage of silver in the alloy = 22% = 0.22

Mass of silver in 2000 g alloy = 0.22 * 2000 g

Mass of silver in 2000 g alloy = 440 g

Number of moles of silver in 440 g of silver is determined using the formula below:

number of moles = mass / molar mass

molar mass of silver = 108 g/mol

number of moles of silver = 440 /108

number of moles of silver in the alloy = 4.074 moles

Step 4: Calculate the volume of HCl required

Since 1 mole of Cl⁻ ions react with 1 mole of Ag; 4.074 moles of Cl⁻ ions will be required to react with 4.074 moles of Ag.

1 L of HCl solution contains 11.53 moles of Cl⁻

Volume of HCl solution that contains 4.074 moles of Cl⁻ = 4.074 * 1L/11.53

Volume of HCl that contains 4.074 moles of Cl⁻ = 0.353 L

Since 1.5 times the amount of precipitating reagent HCl is required, volume of HCl required = 1.5 * 0.353 L

Volume of precipitating reagent HCl required = 0.530 L

Therefore, the volume of precipitating reagent, HCl required to precipitate silver in the form of AgCl from 2,000 g of an alloy containing 22% by weight of Ag is 0.530 L

C2H3Br2 by 2
So c4h6Br4

What is empirical formula?

Empirical formula gives the proportion of the element that is present in a compound. It does not give information about the actual number or the arrangements of the atoms.

n=empirical formula mass÷ molecular formula mass

n=1,2,3....

empirical formula mass = 373.69 g/mol

molecular formula mass=  186.85 g/mol

substituting all the given values in the above formula, we get

n=  186.85 g/mol÷  373.69 g/mol

   = 2

Multiply C[tex]_2[/tex]H[tex]_3[/tex]Br[tex]_2[/tex] by 2, which comes out to be C[tex]_4[/tex]H[tex]_6[/tex]Br[tex]_4[/tex].

The mole ratio of the acid, H₂X (nA) = 1The mole ratio of base, NaOH (nB) = 2

From the question given above, the following data were obtained:
