Bro nobody is gonna do that
Answer:
At higher temperatures, particles move faster and collide more, increasing solubility rates.
Agitation increases solubility rates as well, by bringing fresh solvent into contact with the undissolved solute
The smaller the particle size, the higher (faster) solubility rate. Vice versa, the bigger the particle size, the lower (slower) solubility rate.
Explanation:
Answer:
-4.1°C
Explanation:
The freezing-point depression (ΔTf) is a colligative property that can be calculated using the following expression:
ΔTf = i × Kf × m
where,
i: van't Hoff factor
Kf: freezing-point depression constant
m: molality
ΔTf = 1.9 × 1.86°C/m × 1.15 m = 4.1 °C
The freezing-point of pure water is 0°C. The freezing-point of this solution is:
0°C - 4.1°C = -4.1°C
Spinach and broccoli are high in Iron. The respiratory system needs constant supplies of iron to maintain healthy blood cells. Not having enough Iron can lead to low numbers of red blood cells, without red blood cells not enough blood will flow to organs, causing iron deficient anemia.
Hope this helps!
