Answer:
i believe the answer is Aluminum (Al)
Explanation:
Each element has an equal amount of protons to electron so i you subtract one of either you will have to subtract from the other to make sure it is stable. aluminum has 13 protons and electrons. Subtracting 3 from it would gkve it the same qualities as Neon.
Answer:
check the attached image. hope it helps
Explanation:
a. What does mol/L mean? mol/L means Molar Concentration
b. Describe in your own words how mol/L compares to grams/liter. (similarities and differences)
<u>Similarities:</u><u> </u>mol/L and grams/liter both are units of concentration.
<u>Differences</u>:
mol/L concentration says how many moles of solute are present in 1L of solution.
grams/liter concentration says how many grams of solute are present in 1L of solution.
3. Describe at least 2 ways in the simulation to change each of the parameters:
a. Volume of solution= evaporating or adding more water
b. amount of solute=reducing the water or evaporating more water
c. Concentration of solute in solution = evaporating or adding more solute
Answer:
Fe2+ (aq) + 2e -> Fe(s)
Explanation:
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
Consider the following reaction:
Mg(s) + Fe2+ (aq) —>Mg2+ (aq) + Fe(s)
Magnesium loses its two valance electrons and oxidized while iron accept two electrons get reduced.
Magnesium is reducing agent while iron is oxidizing agent.
Oxidizing agents:
Oxidizing agents oxidize the other elements and itself gets reduced.
Reducing agents:
Reducing agents reduced the other element are it self gets oxidized.
The answer is d. The answer is that because both of them can reproduce that way.
When we have Kw = 1.2x10^-15
and according to Kw formula:
Kw = [OH-] [H+]
by substitution:
1.2x10^-15 = [OH-][H+]
when the solution is neutral that means:
[OH-] = [H+]
∴1.2X10^-15 = X^2
∴X = 3.46 x 10^-8
∴[OH-] = [H+] = 3.46x10^-8
