Answer:
+1.03 V
Explanation:
The standard emf of the voltaic cell is the value of the standard potential of it, which is calculated by the standard reduction potential (E°).
The standard reduction potential is the potential needed for the reduction reaction happen, and it's determined by the reaction with the hydrogen cell (which has E° = 0.0V). The half-reactions of reduction of Ni⁺² and Ag⁺, are:
Ni⁺²(aq) + 2e⁻ → Ni(s) E° = -0.23 V
Ag⁺(aq) + e⁻ → Ag(s) E° = +0.80 V
The value is calculated by a spontaneous reaction, in which the cell with the greater E° is reduced (gain electrons), and the other is oxidized (loses electrons). So, Ag⁺ reduces.
emf = E°reduces - E°oxides
emf = 0.80 - (-0.23)
emf = +1.03 V
The answer is “D Tissue”

Answer:
D
Explanation:
To answer this question, we will need to write the dissociation equation of aluminum trichloride.
AlCl3 ——-> Al3+ + 3Cl-
It can be seen that when aluminum chloride dissociates, it gives one mole of aluminum ion and three moles of the chloride ion.
From here we can see that the concentration of the aluminum chloride equals that of the aluminum ion while that of the chloride ion is thrice that of the aluminum chloride. This means we simply multiply 0.12M by 3 to get the molarity of the chloride ion while that of the aluminum ion remains the same
This works because it demonstrates that as volume increases, pressure decreases (inverse relationship)
Answer:
"Synchronize" means to place together in terms of time and manner.
Explanation:
- In the word 'synchronize' the prefix added is 'syn'.
- The prefix 'syn' has been derived from the Greek language.
- The prefixes 'syn' and 'sym' are equivalent in terms of their meanings.
- The meaning of the prefix is to put 'together'.
- The words formed by adding the prefix es 'syn' and 'sym' highlights the meaning of togetherness of the specific things.
- Here, the word 'synchronize' means to put together in terms of time and manner.
