Answer:
The neutral atoms of the element have an oxidation number of 0. When the atoms loose their three valence electrons to form ions they then have an oxidation number of +3
Explanation:
I believe it’s that solar energy emits more greenhouse gasses, because solar energy is good for the environment meaning that it does not cause greenhouse gas emissions
Answer:
The higher the pH is, the more the hydroxide ion concentration increases and the more basic the solution becomes.
Explanation:
- When the pH of a solution is less than 7, then solution is called acidic and as the pH decreases the concentration of Hydronium ion increases.
- When the pH is about 7, then the solution is said to be neutral. On the other hand, when the pH is greater than 7, the solution is is said to be basic and as the pH increases the concentration of Hydroxide ions increases.
- Therefore, An acidic solution has a higher concentration of hydrogen ions compared to the concentration of hydroxide ions.
Answer is: <span>a. c6h14 and c10h20.
This pair will </span>most likely form a homogeneous solution because they are both nonpolar substances and "li<span>ke dissolves like".
Other pairs will not form homogeneous solution because nonpolar substances have low solubility in polar or ionic substances (for example LiBr is ionic and C</span>₅H₁₂ is nonpolar).
"NH4+ <----> NH3 + H+
The constant of this equilibrium is: K = Kw / Kb = 1 x 10^-14 / 1.8 x 10^-5 =5.56 x 10^-10
5.56 x 10^-10 = x^2 / 0.20-x
x = [H+] =1.1 x 10^-5 M
pH = 5.0"
