Answer: Understanding the timing and processes of synthesis and racemization of amino acids on asteroid parent bodies is crucial to showing how amino acids in living organisms on Earth grew to be predominantly left-handed. It has been postulated that racemization can occur rapidly depending on several factors, including the pH of the aqueous solution.Here, within the Tagish Lake carbonaceous chondrite, we perform a nanoscale geochemical analysis of a framboidal magnetite grain to show that the interlocking crystal structure formed within a sodium-rich, alkaline fluid environment. We study, in particular, on the discovery of Na-enriched subgrain boundaries and layers of Ca and Mg nanometer-scale surrounding individual framboids.

Answer:
280.8 g
Explanation:
Definimos la reaccion:
2NaOH + FeSO₄ → Na₂SO₄ + Fe(OH)₂
Como tenemos la masa de NaOH, asumimos que el sulfato de hierro (II) es el reactivo en exceso.
Definimos masa de reactivo: 250 g . 1mol / 40g = 6.25 mol
2 moles de NaOH producen 1 mol de hidroxido ferroso
Entonces 6.25 moles producirán, la mitad (6.25 . 1) /2 = 3.125 moles
Convertimos los moles a masa:
3.125 mol . 89.85 g/mol = 280.8 g
Answer:
31.9 °C
Explanation:
The formula for the heat q absorbed by an object is
q = mCΔT where ΔT = (T₂ - T₁)
Data:
q = 12.35 cal
m = 19.75 g
C = 0.125 cal°C⁻¹g⁻¹
T₂ = 37.0 °C
Calculations
(a) Calculate ΔT
q = mCΔT
12.35 cal = 19.25 g × 0.125 cal°C⁻¹g⁻¹ × ΔT
12.35 = 2.406ΔT °C⁻¹
ΔT = 12.35/(2.406 °C⁻¹) = 5.13 °C
(b) Calculate T₂
ΔT = T₂ - T₁
T₁ = T₂ - ΔT = 37.0 °C - 5.13 °C = 31.9 °C
The original temperature was 31.9 °C.
