A neutral atom has high electronegativity.

Describe what happens to this atom during ionic bond formation.

Answers

Please get it cleared and stored into your cerebrum that a cation is formed when a neutral atom loses one or more electrons from its valence electron shell.

However too, on other hand an anion is formed when a neutral atom gains one or more electrons in its outermost electron shell.

A cation means a positive ion

An anion means a negative ion

What is electronegativity?

Electronegativity is one of physical periodicity and property of elements that describes the tendency of an atom to attract electrons toward itself.

Generally, electronegativity of an atoms of elements in a particular trend is affected by both its atomic number and the distance that its valence electrons reside from the charged nuclei.

an analyst prepared a sucrose solution by weighing 1kg of water and add 1.5kg sucrose. estimate the concentration of the resultant solution in degree brix

Answers

The concentration of the solution is 60 degrees Brix.

What is degree Brix?

Degrees Brix is the sugar content of an aqueous solution. One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution a as percentage by mass.

Mass percent refers to the percentage of solute present in the solution.

The concentration of the substance can be expressed in mass percent.

we have to first calculate mass percent.

So, we can write,

Mass percent = mass of solute / mass of solution x 100.

Mass of solution = mass of solute + solvent.

Here, sucrose is the solute and the water is the solvent.

The mass of the solute is 1.5Kg and the mass of the solvent is 1Kg.

Mass of solution = 1.5 + 1 = 2.5 Kg.

Mass percent = 1.5/2.5x100

Mass percent is 60%.

Here, 1% = 1 degree brix.

So here, 60% = 60 degree brix.

Hence, the concentration of the solution is 60 degree brix.

Calculate the pH of a buffer solution consisting of 0.39 M HA (Ka = 8.8 x 10^-6) and 0.2 M NaA.

Answers

Answer:

The pH of the buffer is 4.77

Explanation:

Using Henderson-Hasselbalch equation we can solve the pH of the buffer:

pH = pKa + log [A⁻] / [HA]

Where pH is the pH of the buffer

pKa is -log Ka = 5.056

[A⁻] = [NaA] = 0.2M

[HA] = 0.39M

Replacing:

pH = 5.056+ log [0.2] / [0.39]

pH = 4.77

The pH of the buffer is 4.77

A mixture of hydrogen, helium and chlorine gases are in a container. The hydrogen has a partial pressure of 0.74 atm, the helium has a partial
pressure of 1.96 atm, and the chlorine has a partial pressure of 409 mmHg. What is the total pressure of the mixture, in atm?

Answers

Answer:

3.25 atm

Explanation:

convert   409 mm to atm, then add them all :

 409mm  / 760mm/atm   +   .74     + 1.96 = 3.24 atm

The total pressure of the mixture, in atm, is 3.25 atm

A container contains a mixture of hydrogen, helium, and chlorine gases. The partial pressures of the three gases are as follows: 0.74 atm for hydrogen, 1.96 atm for helium, and 409 mmHg for chlorine. 3.25 atm is the mixture's total pressure.

then multiply 409 mm by 1.0 atm, and then combine them all for total pressure :

409mm  / 760mm/atm   +   .74     + 1.96 = 3.24 atm

When more than one gas is present in a container, each gas exerts pressure, which is how atmospheric pressure is defined. Its partial pressure refers to the pressure of any gas inside the container.

A heterogeneous ore mixture contains 35.0 % In2O3 by mass. How many tons of the ore must be mined to provide 325.0 kg of indium metal? (2000 lb = 1 ton, assume exact)

Answers

Answer:

1.2375 ton of ore

Explanation:

Mass of indium = 325

Formula = In2O3

Molar mass = 277.64 g/mol

Molar mass of indium = (2*114.8)g

229.6 indium is in 277.64 of In2O3

Mass of In2O3 required = 277.64/229.6 x 325

= 392.94kg

35 % In2O3 in ore

For 35 kg = 100 kg required

For 392.94,

100/35 x 392.94

= 1122.686 kg

1122.68 x 2.2

= 2469.9 pounds

2469.9/200

= 1.235 tons of ore

Aqueous sulfuric acid (H2SO4) will react with solid sodium hydroxide (NaOH) to produce aqueous sodium sulfate (Na2SO4) and liquid water (H2O). Suppose 5.88g of sulfuric acid is mixed with 6.3 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to 3 significant digits

Answers

Answer:

2.16 g H₂O

Explanation:

Since we are not given the limiting reagent, we need to convert both reactants into the product. The actual amount of product will be the smaller mass produced.

To find the answer, we need to (1) convert grams reactant to moles reactant (via molar mass), then (2) convert moles reactant to moles H₂O (via mole-to-mole ratio from balanced equation coefficients), and then (3) convert moles H₂O to grams H₂O (via molar mass). It is important to arrange the ratios in a way that allows for the cancellation of units.

The balanced equation:

1 H₂SO₄(aq) + 2 NaOH(s) -----> 1 Na₂SO₄(aq) + 2 H₂O(l)

Molar Mass (H₂SO₄): 2(1.008 g/mol) + 32.065 g/mol + 4(15.998 g/mol)

Molar Mass (H₂SO₄): 98.073 g/mol

Molar Mass (NaOH): 22.990 g/mol + 15.998 g/mol + 1.008 g/mol

Molar Mass (NaOH): 39.996 g/mol

Molar Mass (H₂O): 2(1.008 g/mol) + 15.998 g/mol

Molar Mass (H₂O): 18.014 g/mol

5.88 g H₂SO₄           1 mole              2 moles H₂O            18.014 g
----------------------  x  -----------------  x  ------------------------  x  -----------------  =  
                                98.073 g            1 mole H₂SO₄           1 mole

=  2.16 g H₂O

6.3 g NaOH            1 mole              2 moles H₂O              18.014 g
--------------------  x  -----------------  x  --------------------------  x  ----------------  =
                              39.996 g           2 moles NaOH            1 mole

=  2.84 g H₂O

Since H₂SO₄ produces the smallest amount of product, it is the limiting reagent. In this case, H₂SO₄ is completely used up before NaOH has the chance to react totally. Therefore, the actual amount of H₂O produced is 2.16 g.

Enthalpy of reaction of nitrogen dioxide (use Hess Law)

N2(g) + 2O2(g) → 2NO2(g)

N2 + O2 → 2NO Hr= +180 kJmol-1
2NO + O2 → 2NO2 Hr= -112 kJmol-1

Starting Point Ending point
N2 (g) + 2O2 (g) → 2NO2 (g)

+180kJ -112kJ
2NO2 + O2 (g)

Use the information to calculate the H and explain how you got your answer.

Answers

Considering the Hess's Law, the enthalpy change for the reaction is 68 kJ/mol.

Hess's Law

Hess's Law indicates that the enthalpy change in a chemical reaction will be the same whether it occurs in a single stage or in several stages. That is, the sum of the ∆H of each stage of the reaction will give us a value equal to the ∆H of the reaction when it occurs in a single stage.

Enthalpy of reaction of nitrogen dioxide

In this case you want to calculate the enthalpy change of:

N₂ + 2 O₂ → 2 NO₂

which occurs in two stages.

You know the following reactions, with their corresponding enthalpies:

Equation 1: N₂ + O₂ → 2 NO     ΔH = 180 kJ/mol

Equation 2: 2 NO + O₂ → 2 NO₂     ΔH = –112 kJ/mol

Because of the way formation reactions are defined, any chemical reaction can be written as a combination of formation reactions, some going forward and some going back.

In this case, first, to obtain the enthalpy of the desired chemical reaction you need one mole of N₂ on reactant side and it is present in first equation so let's write this as such.

In the same way, you need two moles of NO₂ on product side and it is present in second equation so let's write this as such.

Finally, in this way the two moles of NO cancel.

Then, it is not necessary to modify the given equations. So, adding or canceling the reactants and products as appropriate, and adding the enthalpies algebraically, you obtain:

N₂ + 2 O₂ → 2 NO₂     ΔH= 68 kJ/mol

Finally, the enthalpy change for the reaction is 68 kJ/mol.

Why do particles with different masses have the same kinetic energy when at the same temperature?

Answers

Answer: Because Kinetic energy depends on temperature and not mass

Explanation:

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

[tex]K.E=\frac{3RT}{2}[/tex]

where K.E = Kinetic energy

R= gas constant

T= temperature in kelvin

It is visible that kinetic energy is dependent on the temperature of the system and not on the mass of the system. Thus particles with different masses have the same kinetic energy when at the same temperature
