Answer:
The salt of benzoic acid would dissolve in the aqueous layer while cyclohexanol would remain in the CH2Cl2 layer.
Explanation:
The pH at which the amino acid exists primarily in its neutral form. hope this helps you :)
Answer: I think the alcohol molecules slip between the water molecules and take up that space, so you have less that you started with.
Explanation:
<u>Answer:</u>
<em>D. The reverse reaction rate increases.</em>
<u>Explanation:</u>
The<em> rate of reverse</em> increases if the products are increased in a mixture at equilibrium.
At first,<em> rate of forward and backward</em> reactions are same for a <em>mixture in equilibrium.
</em>
<em>If we add products or,the reaction moves to the opposite side I.e towards reactants side.</em>
so,according to the Le Chateliers principle,the reaction shifts opposite to the side of increase. so,according to the Le Chateliers priciple, <em>the rate of reverse or backward reaction will increase with the increase in the products.</em>
CaCO₃ → CaCl₂
Ca = 40, C = 12, O = 16, Cl = 35.5
100 →111
3 → x
x = 3.33g
Answer:
Mass = 16.4 g
Explanation:
Given data:
Mass of K = 8.50 g
Mass of KCl produced = ?
Solution:
Chemical equation:
2K + Cl₂ → 2KCl
Number of moles of K:
Number of moles = mass/ molar mass
Number of moles = 8.50 g/ 39 g/mol
Number of moles = 0.22 mol
Now we will compare the moles of potassium and potassium chloride.
K : KCl
2 : 2
0.22 : 0.22
Mass of KCl:
Mass = number of moles × molar mass
Mass = 0.22 mol × 74.55 g/mol
Mass = 16.4 g
