Answer:
nahhhhhhhhhhhhhhhhhhhhhhh xD
have a good day :)
Explanation:
Answer:
e. all of these
Explanation:
Let us check all the given options one by one:
a.The nucleus is positively charged.
Yes it is correct since nucleus contain protons and neutrons and protons are positively charged.
b.The nucleus contains both charged and uncharged particles.
Yes because protons are positively charged and neutrons are neutral in nature.
c.The electrons contribute very little to the total mass of the atom.
Yes we know all the mass of the atom is considered in center and mass of electron is negligible as compared to protons and neutrons.
d.The electrons are located in the atomic space outside the nucleus.
Yes, its a known fact.
e. All of these.
Since , all given options are correct .
Therefore , option e. is right .
<u>Given information:</u>
A solution with a high H+ ion concentration
<u>To determine:</u>
The nature of pH of such a solution
<u>Explanation:</u>
pH is a measure of the H+ ion concentration in a given solution. Lower the pH higher will be the H+ concentration and the solution is termed acidic. In contrast, if the pH is higher the H+ concentration will be lower and the solution is basic.
Mathematically,
pH = -log[H+]
[H+] = 
pH = 2; [H+] = 10⁻²M
pH = 7; [H+] = 10⁻⁷M
pH = 13; [H+] = 10⁻¹³M
pH = 14; [H+] = 10⁻¹⁴M
Ans: (a)
Thus, the highest concentration of H+ ions is for a solution of pH = 2
