How many atoms of N (nitrogen) are there in 1 mole of NH4Cl?

Answers

Answer:

In one mole of NH₄Cl  6.022 × 10²³ atoms of N are present.

Explanation:

Given data:

Number of atoms of N = ?

Number of moles of NH₄Cl = 1 mol

Solution:

First we have to calculate the number of  atoms in NH₄Cl .

There is only 1 mole of N in 1 mole of NH₄Cl .

Now we will calculate the number of atoms of nitrogen in one mole of N  by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1  mole of N = 6.022 × 10²³ atoms of N

Thus in one mole of NH₄Cl  6.022 × 10²³ atoms of N are present.

Liquid hexane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 17. g of hexane is mixed with 101. g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.

Answers

Answer:

52g of carbon dioxide

Explanation:

Liquid hexane + gaseous oxygen --> Carbon dioxide + gaseous water

The balance chemical equation is given as;

C6H12 + 9O2 --> 6CO2 + 6H2O

From the stochiometry of the reaction;

1 mol of hexane (86g) would consume 9 mol of oxygen (144g) to form 4 mol of carbon dioxide (264g)

The limiting reactant in this equation is hexane as it would run out before oxygen. This means hexane determines how much of the carbon dioxide is formed.

86g of hexane = 264g of crbon dioxide

17g of hexane = xg of carbon dioxide

x = 17 * 264 / 86 =  52g of carbon dioxide

If you are given 22.990 g of sodium and 12.011 g of carbon, which sample do you expect to have more particles?

Answers

Answer:

they are expected to have the same particles because their masses are the same with there molar mass

Kinetic and potential energy are two types of energy that relate too

Answers

Answer:

Option B. A tractor–trailer traveling at 80 kph.

Explanation:

Kinetic energy can be defined as the energy possessed by a body in motion. Mathematically, it is expressed as:

K.E = ½mv²

Where:

K.E is the kinetic energy.

m is the mass of the object.

v is the velocity of the object.

From the equation, K.E = ½mv²,

We can say that the kinetic energy (K.E), is directly proportional to both the mass (m) and square of the velocity (v). This implies that the greater the mass of an object, the greater the kinetic energy and the smaller the mass, the smaller the kinetic energy.

Now, considering the options given in question above, it is evident that the tractor–trailer has a greater mass than the car, cheetah and motor cycle. Hence, the tractor–trailer will have a greater kinetic energy even though they are traveling with the same velocity.

Answer:

the mean is 6 but you don't have that as an option.

Explanation:

the mean is the average.

to find the mean you have to add all of your data first

3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48

then you have to divide your answer by how many numbers there are in total.

48 / 8 = 6

The sulfuric acid–catalyzed reaction of isopentyl alcohol with acetic acid to form isopentyl acetate is performed. This reaction does not proceed to completion. After the reaction is heated under reflux for an hour, the product mixture is washed with aqueous sodium bicarbonate solution, and the organic layer is thoroughly dried. A distillation of the organic layer is then performed. Given the boiling points listed below, select the compound that will distill first.
Compound Boiling point, ℃
acetic acid 118
isopentyl acetate 142
isopentyl alcohol 130
sulfuric acid water 290

Answers

Answer:

The correct option is acetic acid

Explanation:

Distillation is the process of separating a mixture of substances based on differences in boiling points. During distillation, the compound with the lowest/least boiling point is distilled and collected first and then the one with the next least boiling point and it goes on like that.

From the explanation above, acetic acid has the least boiling point (in the organic layer) with 118°C and thus will distill first. This is then followed by isopentyl alcohol (130°C) and then isopentyl acetate (142°C) and finally sulfuric acid water (290°C).

10. What is the change in the boiling point of water at 1000 C per Pa change under atmospheric pressure conditions? The molar enthalpy of vaporization is 40.69 kJ mol-1, the molar volume of liquid water is 0.019 x 10-3 m3 mol-1, and the molar volume of steam is 30.199 x 10-3m3 mol-1, all at 1000 C and 1.01325 bar. (Hint: change in temperature per change in pressure)

Answers

Answer:

The answer  is  [tex]\frac{dT}{dP} = 2.84*10^{-4}\ K/Pa[/tex]

Explanation:

From the question we are told that

  The boiling point of water is  [tex]T_b = 100^oC = 100 + 273 = 373 \ K[/tex]

  The enthalpy of vaporization is  [tex]\Delta H_{vap} = 40.69 \ kJ mol-1 = 40.69 *10^{3} \ J/mol[/tex]

  The molar volume of liquid water is  [tex]V =0.019 * 10^{-3} m^3 mol^{-1}[/tex]

   The molar volume of steam is  [tex]V_s = 30.199 * 10^{-3} \cddot m^3\cdot mol^{-1}[/tex]

  The pressure is  [tex]P = 1.01325 \ bar[/tex]

Gnerally from Clausius Clapeyron equation we have that

      [tex]\frac{dP}{dT} = \frac{\Delta H_{vap}}{ T * \Delta V}[/tex]

Here  [tex]\Delta V = V_s - V[/tex]

=>     [tex]\Delta V = [30.199 * 10^{-3} ] - [ 0.019 * 10^{-3}][/tex]

=>     [tex]\Delta V = [30.199 * 10^{-3} ] - [ 0.019 * 10^{-3}][/tex]      

=>     [tex]\Delta V = 0.03018 \ m^3 mol^{-1}[/tex]          

So

    [tex]\frac{dP}{dT} = \frac{40.69 *10^{3} }{ 373 * 0.03018}[/tex]

=>  [tex]\frac{dP}{dT} = 3522.28 \ Pa/K[/tex]

Generally from the we are ask to obtain the change in the boiling point of water at 1000 C per Pa change under atmospheric pressure conditions which is mathematically represented as

       [tex]\frac{d T}{dP}[/tex]

So

    [tex]\frac{dT}{dP} = \frac{1}{\frac{dP}{dT} } = \frac{1}{3522.28}[/tex]

=> [tex]\frac{dT}{dP} = \frac{1}{\frac{dP}{dT} } = 2.84*10^{-4}\ K/Pa[/tex]

Rank lead, phosphorus, and barium in order of increasing ionization energy.
A) Pb < P < Ba
B) Ba < P < Pb
C) Pb < Ba < P
D) Ba < Pb < P

Answers

Answer:

D) Ba < Pb < P

Explanation:

Barium (Ba): 5,2117

Lead (Pb): 7,4167

Phosphorus (P): 10,4867

Increasing order of ionization energy:

Ba < Pb < P

Electronic configurations of given elements

Pb: [Xe] 6s² 4f¹⁴ 5d¹⁰ 6p²

P:   [Ne] 3s² 3p³

Ba: [Xe] 6s²

All the given elements have stable half-filled subshells. But phosphorus has the smallest atomic size among them, so it will have the lowest tendency to remove an electron from its valence shell and hence will require the highest amount of ionization energy.  Barium has a higher atomic size than lead, therefore it has lower ionization energy than lead.

How are ionization energy and atomic size related?The force of attraction is stronger when the electron is closer to the nucleus, and as a result, more energy is needed to overcome this attraction and remove the electron.Therefore, the ionization energy increases with decreasing radius and vice versa.

a)2

b)12.5

c)1.5

Explanation:

a)

pH = -log [H^+]

pH = -log [0.01]

pH = 2

b)

pOH = -log[OH^-]

pOH = -log [0.035]

pOH= 1.5

But

pH + pOH = 14

pH = 14 - pOH

pH= 14 - 1.5

pH = 12.5
