<span>Ionic compounds form crystal lattices, not molecules. The term formula unit is used to indicate the simplest whole-number ratio of ions in the compound.</span>
The answer is c :) i hope its the right answer
Answer:
b. + 1.01 V
Explanation:
Sn(s) ⇒ Sn2+ + 2e⁻ Eox = 0.14 V
Ag₊ + e⁻⇒ Ered = 0.80 V
_______________________________
Sn(s) + Ag⁺(aq) ⇒ Sn2⁺(aq) + Ag(s) Eºcell = 0.14 V + 0.80 V = 0.94 V
This problem is solved by using the Nernst equation:
Ecell = Eºcell - (0.0592 / n) log Q
since we are not at standard condition given that the concentrations are not at 1 M. So we will calculate Q first
Q = ( Sn²⁺ ) / ( Ag⁺) = 0.022/2.7 = 0.0081
Ecell = 0.94 V -(0.0592/2) x log (0.0081) = 1.00 V
Answer is: 2) 14/7 N + 4/2 He --> 17/8 O + 1/1 H.
Transmutation is a process that involves a change in the nucleus of an atom. It can be natural or artificial.
This example is the first artificial nuclear transmutation described by Rutherford in 1919.
Artificial transmutation can be expressed by nuclear reaction:
Target Nuclide + Bombardment Particle → New Nuclide + Ejected Particle.
Answer: B) KCl
Explanation: Potassium chloride, KCl , is an ionic compound formed by the electrostatic force of attraction that holds the potassium cations and the chlorine anions together. Potassium, K , is located in group 1 of the Periodic Table.
