Oh wow , what grade are you in ukliblo ?
C. A compound !hope this helps!
Answer:
Correct option is B. It shows the ratio of elements in the compound.
Explanation:
Empirical formula is the simplest form of the chemical formula. It shows the simplest ratio of atoms in compounds. It is determined by %age of each element.
Answer:
1.0 × 10⁻⁵ mol/L
Explanation:
The concentration of a gas (C) in a liquid depends on its partial pressure (P), as expressed in Henry's law.
C = k × P
where,
k is the henry's law constant
When the partial pressure of the gas equilibrates at 3.0 × 10⁻⁴ atm, its concentration in the liquid is:
C = k × P
C = 3.4 × 10⁻² mol/L.atm × 3.0 × 10⁻⁴ atm
C = 1.0 × 10⁻⁵ mol/L
