Answer:

Kf

Explanation:

The stability constant Kf of a given complex specie is an equilibrium constant that represents the formation of that particular complex specie in solution. It measures the strength of the interaction between the ligands and metal that form the particular complex specie. The magnitude of Kf shows how easily a complex specie is formed in solution.

Hence if I want to dissolve the bromides or chlorides of silver which are ordinarily insoluble in water by means of complex formation, the magnitude of the stability constant for each particular complex specie is important as it gives information regarding the thermodynamic feasibility of the process.

Since the number of atoms in a substance is so large , a unit to count them was created. This unit is the number of atoms in 12
larisa86 [58]

The number of atoms in one mole of any substance is measured by Avogadro's number. The value of Avogadro's number is 6.023 x 10 ^23. It is named after scientist Avogadro who proposed this number. 12 grams of carbon-12 represents 1 mole of carbon-12. For this reason, the number of atoms present in 1 mole of any substance is 6.023 x 10 ^23. Therefore, the number of atoms present in 1 mole carbon-12 is 6.023 x 10^23.


(Answer) This unit is the number of atoms in 12 grams of carbon-12 and known as Avogadro's number.

How many liters of hydrogen gas are formed from the complete reaction of 1.04 mol of C? Assume that the hydrogen gas is collecte
Alisiya [41]

The volume is 2.23 liters of hydrogen gas.

<u>Explanation</u>:

                  moles of C = grams / molecular mass of C

                                     = 1.04 g / 12.011 g/mol.

                                     = 0.086

        The ratio between C and H2 is 1 : 1

                 moles H2 = 0.086

                               V = nRT / p

                                  = 0.086 x 0.08206 x 316 K / 1.0 atm

                              V  = 2.23 L.

<h2>The compound formed is NaCl and CaCl_{2}</h2>

Explanation:

     PART 1:

  • Atomic number of sodium is 11.
  • Sodium(Na, Z = 11, Group 1A) will lose 1 electron to become Na^{1+} which is isoelectronic to Neon (Ne ,Z = 10).
  • The symbol for the sodium ion is Na^{+}.
  • Chlorine atom (Cl, Z = 17, Group 7A or 17) gains 1 elecron to be  isoelectronic to neon.
  • The symbol for the compound formed is NaCl.
  • PART 2:
  • Atomic number of calcium is 20
  • Calcium(Ca, Z = 20 ,Group 2A) will lose two electrons to become Ca^{2+}which is isoelectronic to argon.
  • The symbol for the ion is Ca^{2+}.
  • Two chlorine atoms (Cl, Z = 17, Group 7A or 17) each gains one electron to be isoelectronic to argon(Z = 18)
  • The symbol for the compound formed is CaCl_{2}.
