The best answer between the two choices would be the first option TRUE because the scientific method is used to do more advance research and investigation on things.
The answer is they follow a patter for valence electrons.
Answer:
empirical formula is C7H3NCl2
Explanation:
too much work too explain and im lazy
PH + pOH = 14 ⇒ pOH = 14 - pH
pOH = 14 - 2.5
pOH = 11.5
[H⁺] = 10^(-pH) = 10^(-2.5)
[H⁺] = 0.003 M
[OH⁻] = 10^(-pOH) = 10^(-11.5) = 3 × 10⁻¹² M
[OH⁻] = 3 × 10⁻¹² M
pH = 2.5 implies one significant digit
