Answer:
a chemical reaction or other process in which the products themselves promote or spread the reaction, which under certain conditions may accelerate dramatically.
Explanation:
the self-sustaining fission reaction spread by neutrons which occurs in nuclear reactors and bombs.
a series of events, each caused by the previous one.
Answer:
Explanation:
Given parameters:
Concentration of H₃O⁺ = 5.6 x 10⁻²M
Solution:
To solve for the concentration of H₃O⁺ in the solution, we simply use the expression below:
pH = -log₁₀[H₃O⁺]
where [H₃O⁺] = 5.6 x 10⁻²M is the concentration of H₃O⁺
pH = -log₁₀[5.6 x 10⁻²] = - x -1.25 = 1.25
Answer:
(a) X electrode
(b) Y electrode
(c) Y electrode
(d) X electrode
(e) Y electrode
Explanation:
<em>A galvanic (voltaic) cell has the generic metals X and Y as electrodes. X is more reactive than Y, that is, X more readily reacts to form a cation than Y does.</em>
In the X electrode occurs the oxidation whereas in the Y electrode occurs the reduction.
Oxidation: X(s) → X⁺ⁿ(aq) + n e⁻
Reduction: Y⁺ˣ(aq) + x e⁻ → Y(s)
<em>Classify the descriptions by whether they apply to the X or Y electrode.
</em>
<em>(a) anode.</em> Is where the oxidation takes place (X electrode).
<em>(b) cathode.</em> Is where the reduction takes place (Y electrode).
<em>(c) electrons in the wire flow toward.</em> Electrons in the wire flow toward the cathode (Y electrode).
<em>(d) electrons in the wire flow away.</em> Electrons in the wire flow away from the anode (X electrode).
<em>(e) cations from salt bridge flow toward.</em> Cations from the salt bridge flow toward the cathode (Y electrode) to maintain the electroneutrality.
