Answer:
restrict population growth ( second choice).
Answer:
3.018 x 10⁻⁶ M.
Explanation:
- Co(OH)₂ dissociates in solution according to the equation:
<em>Co(OH)₂ → Co²⁺ + 2OH⁻.</em>
∵ Ksp = [Co²⁺][OH⁻]² = (s)(2s)² = 4s³.
∴ 4s³ = 1.10 x 10⁻¹⁶.
∴ s³ = 1.10 x 10⁻¹⁶/4 = 2.75 x 10⁻¹⁷.
<em>∴ s</em> = ∛(2.75 x 10⁻¹⁷) = <em>3.018 x 10⁻⁶ M.</em>
Answer:
36.8 g/mol of O
Explanation:
To find the number of grams, multiply the number of moles by the atomic mass of the element.
Oxygen has an atomic mass of 16.00.
2.3 moles O × (16.00 g O ÷ 1 mole) = 36.8 g/mol O
Hope that helps.
Answer:
0.6 atm
Explanation:
We have a state change at a constant temperature. For isothermal transformations, Boyle proposed the equation:
P1V1 = P2V2 (Boyle's Law)
Where P1 and V1 are the pressure and the volume in the first state and P2 and V2 the pressure and the volume at the final state. So:
4x3 = 20xP2
20xP2 = 12
P2 = 0.6 atm
