Consider the chemical equilibrium of a soap that is present in its aqueous solution. C17H35COONa(aq) mc017-1.jpg C17H35COO–(aq)

+ Na+(aq) sodium stearate (soap) stearate ion What will happen if a large quantity of NaCl is added to the aqueous solution?
A)The equilibrium will shift to the right, favoring the dissociation of soap in aqueous solution.
B)The equilibrium will shift to the left to such an extent that it leads to the precipitation of solid soap.
C)The equilibrium will not be affected by the addition of NaCl to the solution.
D)The equilibrium will be permanently destroyed by the addition of NaCl.

Answer : Option B) The equilibrium will shift to the left to such an extent that it leads to the precipitation of solid soap.

Explanation : The equilibrium will tend to shift to left because addition of sodium chloride salt will lead to precipitate the soap as a product. The volume increase in the sodium ions because of sodium chloride addition will generate the more amount of solid soap.

B.

The shift to the left will be due to the fact that sodium ions will be released when NaCl is dissolved in the solution.

When the electron from the n=4 excited state drops to the ground state, does it absorb energy or emit energy?
zubka84 [21]

Answer:

It emits energy since to move from a higher energy level to a lower energy level or ground state, it must lose energy.

Situation 1
SIZIF [17.4K]

Answer:

3. 17

4. 18

5. 10

6. Cation

7. 35

8. 81

9. 36

10. Anion

11. 37

12. 48

13. +1

14. Cation

15. 5

16. 5

17. 2

18. Cation

Explanation:

Situation 1

The mass number = 35 = The sum of the protons and the neutrons in an atom

The number of protons = 17

The net charge = 1

3. The atomic  number = The number of proton = 17

4. The number of neutrons = Mass number - Atomic number

∴ The number of neutrons = 35 - 17 = 18

5. Given that the net charge of the atom = +1, the number of electrons in the atom is 1 less than the number of protons

Therefore, the number of electrons = 11 - 1 = 10

6. Positively charged ions are called a cation

The atom is a positively charged and it is therefore it is a cation

Situation 2

The number of protons =  35

The number of neutrons = 46

The net charge = -1

7. The atomic number = The number of protons = 35

8. The mass number = The number of protons + The number of neutrons

∴ The mass number = 35 + 46 = 81

9. The number of electrons = The number of protons + 1

∴ The number of electrons = 35 + 1 = 36

10. The type of atom is an anion

Situation 3

Atomic number = 37

Mass number = 85

Number of electrons = 36

11. The number of protons = The atomic number = 37

12. The number of neutrons = The mass number - The atomic number

∴ The number of neutrons = 85 - 37 = 48

13. The net charge = The atomic number - The number of electrons

∴ The net charge = 37 - 36 = +1

14. Given that the net charge = +1, the type of atom is a cation

Situation 4

Mass number = 11

Number of neutrons = 6

Net charge = +3

15. The atomic number = The mass number - The number of neutrons

∴ The atomic number = 11 - 6 = 5

16. The number of protons = The atomic number = 5

17. Given that the net charge is +3, we have;

The number of electrons = The number of protons - The net charge

∴ The number of electrons = 5 - (+3) = 2

18. The type of atom with a net positive charge (+3) is a cation

What is the temperature of the gas inside a 750 ml balloon filled with 0.30 g hydrogen gas? The pressure of the balloon is 1.2 a
zhenek [66]
Use the ideal gas law: PV = nRT, and solve for T,

T = PV/nR.

We should convert any of our parameters to units that would be easy to use with a known R value. One option would be to have the pressure in atm, volume in L, and convert the mass of the hydrogen gas to moles:

P = 1.2 atm
V = 750 mL = 0.750 L
n = (0.30 g H2)/(2.0159 g/mol) = 0.1488 mol H2
R = 0.0821 L•atm/mol•K.

Solving for T,

T = (1.2 atm)(0.750 L)/(0.1488 mol H2)(0.0821 L•atm/mol•K) = 73.671 K.

If you opt to leave your temperature in Kelvin, I would go with 74 K, as that has two significant figures like the rest of the values.

If you opt to go with Celsius, then the answer would be a bit awkward if you had to follow two sig figs: 73.671 - 273.15 = -199.49 ≈ -2.0 × 10² °C.

Pick your poison, I suppose.
