L = 0 to n-1. Hence, it can have values 0, 1, 2.
<span>m = -l to +l. Hence, it can have values -2, -1, 0, 1, 2 </span>
<span>s = +1/2 and -1/2</span>
The metric system prefix for the above quantity would be D. Micro. Which is 10^-6.
Manipulated variable: the types of soil
Responding variable: how much t the plants grow
Answer is: D. Na2SO4.
b(solution) = 0.500 mol ÷ 2.0 L.
b(solution) = 0.250 mol/L.
b(solution) = 0.250 m; molality of the solutions.
ΔT = Kf · b(solution) · i.
Kf - the freezing point depression constant.
i - Van 't Hoff factor.
Dissociation of sodium sulfate in water: Na₂SO₄(aq) → 2Na⁺(aq) + SO₄²⁻(aq).
Sodium sulfate dissociates on sodium cations and sulfate anion, sodium sulfate has approximately i = 3.
Sodium chloride (NaCl) and potassium iodide (KI) have Van 't Hoff factor approximately i = 2.
Carbon dioxide (CO₂) has covalent bonds (i = 1, do not dissociate on ions).
Because molality and the freezing point depression constant are constant, greatest freezing point lowering is solution with highest Van 't Hoff factor.
6 - one sodium atom, 1 hydrogen atom, 1 carbon atom, and 3 oxygen atoms.
