Gravitational potential energy, kinetic energy, elastic potential energy and back to kinetic energy again
Answer
is: molar solubility of barium carbonate is 4.47·10⁻⁵ M.
Chemical
reaction:BaCO₃(s) →
Ba²⁺(aq) + CO₃²⁻(aq).
Ksp
= 2.0·10⁻⁹.
s(BaCO₃) = ?M.
s(BaCO₃) = s(Ba²⁺)
=s(CO₃²⁻) = x.
Ksp
= s(Ba²⁺) · s(CO₃²⁻).
Ksp
= x · x.
2.0·10⁻⁹ =
x².
x
= √2.0·10⁻⁹ = 4.47·10⁻⁵
M.
These nutrient classes can be divided into macronutrients (nutrients required in large quantities) and micronutrients (nutrients required in tiny quantities). Carbohydrates, proteins, lipids, fiber, and water are macronutrients, whereas vitamins and minerals are micronutrients.
1.78L x (3.00M/1L) = 5.34
Answer:
The reason is that sodium attaches itself very strongly to other elements. Its compounds are very difficult to break apartand also because it is so reactive.
