The solutions having pOH=3.37, [h+]=3.8x10^-4 and pH=5.11 are acidic. Solutions with pOH=11.40, [OH-]=6.6x10^-3 and pH=12.94 are basic. The solution with [h+]=1.0x10^-7 is neutral. The solutions with [h+]=5.8x10^-8 and [OH-]=3.5x10^-12 are mildly acidic and basic respectively.
In an aqueous solution at 25 °C, the pH and pOH scales are defined so that water, which is neutral, has a pH of 7.00 and a pOH of 7.00. If the pH is less than 7, the solution is acidic. If the pH is greater than 7, the solution is basic. Hence, solutions with pOH=3.37 and [h+]=3.8x10^-4 are acidic, as they would have a pH lower than 7. The solutions with pOH=11.40, [OH-]=6.6x10^-3 and pH=12.94 are basic, as they would have a pH higher than 7. The solution with [h+]=1.0x10^-7 is neutral as it has a pH of 7. The solutions with [h+]=5.8x10^-8 and [OH-]=3.5x10^-12 are slightly acidic and basic respectively due to being close to the pH of 7. The solution with pH=5.11 is acidic as it's less than 7.

The given solutions can be classified based on pH, pOH, [H+] and [OH-]. Based on these values, they are categorised as acidic, basic, or neutral.
The values provided are measures of the concentration of Hydronium ions [H+], hydroxide ions [OH-], pH, and pOH, which help determine whether a solution is acidic, basic, or neutral. At 25 degrees Celsius, a neutral solution has pH = 7, pOH=7, [H+] = 1.0x10^-7, and [OH-] = 1.0x10^-7. If the pH or [H+] is less than 7, or pOH or [OH-] is greater than 7, the solution is acidic. If the pH or [H+] is greater than 7, or pOH or [OH-] is less than 7, the solution is basic.
Applying this for each solution: pOH=3.37, acidic; pOH=11.40, basic; [H+]=3.8x10^-4, acidic; [H+]=5.8x10^-8, acidic; [OH-]=3.5x10^-12, acidic; [OH-]=6.6x10^-3, basic; [H+]=1.0x10^-7, neutral; pOH=7, neutral; pH=5, acidic; pH=12.94, basic.

A. They have the same shape.
B. They are made of only one kind of atom.
c. They have the same number of atoms.
D. They have the same mass.
Answer:
B
Explanation:
If they were to be made of the same element they would only be made of the same kind of atom.
Answer:
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
The equation for the ionization of the is given as:
Molar concentration =
By stoichiometry of the reaction:
1 mole of gives 1 mole of and 1 mole of
When the solubility of is S moles/liter, then the solubility of will be S moles\liter and solubility of will be S moles/liter.
Thus of the salt at is
Magnesium oxide (MgO) is an ionic compound formed by the transfer of electrons from magnesium to oxygen, resulting both atoms being electronically stable. Its properties include having high melting and boiling points, being a good electrical insulator but a thermal conductor.
Magnesium oxide, often referred to as 'MgO,' is a compound comprised of two different elements: magnesium and oxygen. It is a type of ionic compound because it is formed by a metal, magnesium, and a non-metal, oxygen. This creation occurs through a process called ionic bonding, where the magnesium atom effectively donates two electrons to the oxygen atom. Consequently, both atoms achieve a stable electronconfiguration.
In its solid state, MgO takes a form of a white, crystal-like substance. It's generally known for its high melting and boiling points, reflecting the strong ionic bonds in oxide structure. Furthermore, the compound stands out for being a good electrical insulator, but a thermal conductor.

Answer:
Second graph is more reactive.
Explanation:
I just did the lesson myself, chose the first graph, and obviously got it wrong.
Therefore I can tell you with 100% certainty that the correct answer is graph #2 in this case. Hope this helps.
