Answer:
1. Hyphothesis 2.Theory 3. law
Explanation:
not sure, but law is observation, theory is based on knowledge things before.
PH scale is used to determine how acidic , basic or neutral a solution is. It can be calculated using the following equation
pH = -log [H₃O⁺]
hydronium ion concentration has already been given
[H₃O⁺] = 4.91 x 10⁻⁴ M
pH = -log[4.91 x 10⁻⁴ M]
pH = 3.3
the pH of medium is 3.3
No it won't lose but it will gain and it gain up to it will fill 8 and because it need to satisfy the octet rule 7 will lose or gain electron and because it needs to stastify the octet rule by filling it up till 8 valence electron
