This is a chemical change because there is a new substance that was created and the new chemical can cause other chemical reaction to happen compared to the 1st state of chemical that was in the cave. Because the cave water was exposed to another environment, the calcium bicarbonate, which is also known as salt. When the cave's groundwater was exposed to a different environment the atom in the cave water rearranged and crystallized.
Answer:
Distribution coefficient: 4.79
Explanation:
Distribution coefficient is the ratio between equilibrium concentration of non-aqueous phase and aqueous phase where both solvents are inmiscible. The equation for the problem is:
Distribution coefficient: Concentration in chloroform / Concentration in Water
<em>Concentration in water: 2.59mg / 30mL = 0.08633mg/mL</em>
<em>Concentration in chloroform: (15mg-2.59mg) / 30mL = 0.4137mg/mL</em>
<em />
Distribution coefficient: 0.4137mg/mL / 0.08633mg/mL
<h3>Distribution coefficient: 4.79</h3>
Answer:
soe are appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many other
Explanation:
M = amount of the solute / mass of the <span>solvent
0.523 = x / 2.00
x = 0.523 * 2.00
x = 1,046 moles
molar mass KI = </span><span>166.0028 g/mol
</span><span>
Mass = 1,046 * 166.0028
Mass </span>≈<span> 173.63 g
hope this helps!
