Answer:
no
Explanation:
they are insectivores, as they have a diet of primarily insects. producers are organisms that make their own energy, like plants, but horned lizards get their energy from consuming other organisms, so they are not producers
Answer:
nonpolar covalent, polar covalent, ionic
Explanation:
From the question ,
S - S Bond -
Both the atom are same , hence , making a non polar bond , because of no difference between the electronegativity of the atom ,
Hence , the S-S Bond is non polar covalent bond .
O-H bond -
The Oxygen atom is more electronegative than the hydrogen atom , so the bond is polar in nature .
And as the bond is formed by sharing ,
Therefore ,
O-H bond is polar covalent bond .
Ca-Cl bond -
Calcium is a metal , whereas , Chlorine is a non - metal , the bond is ionic in nature ,
Hence , Ca-Cl bond is ionic in nature .
To answer this item, we must take note that the ligand that binds the tightest is the one with the lowest dissociation constant, Kd. Kd's for both A and B are already given so, we only need to solve Kds for C and D.
Kd of C
0.3 = (1x10⁻⁶)/(1x10⁻⁶ + Kd) ; Kd = 2.3x10⁻⁶
Kd of D
0.8 = (1x10⁻⁹)/(1x10⁻⁹ + Kd) ; Kd = 2.5x10⁻10
Since Ligand D has the least value of dissociation constant then, it can be concluded that it binds the tightest.
Answer:
Se explanation below
Explanation:
Here we will use the technique of extraction taking advantange of the different solubilities of Phenol and and Benzoic Acid in the NaOH and and NaHCO₃ solvents (In reality their anions). Notice that phenol does not dissolve in the weak base NaHCO₃ so we can have the solution of phenol and benzoic acid in ether and proceed to extract with this weak base, the phenol will remain in solution in the organic ether solution and the sodium benzoate will go into the water layer.
We then will repeat the extraction procedure to separate the phenol from the organic layer by using NaOH instead.
Benzoic Acid /
Phenol/ Ether ⇒Extract w/ ⇒ Organic Layer = Phenol/Ether
10 % NaHCO₃ Aqueous Layer = Sodium Benzoate
Sodium benzoate ⇒ 10 % HCl to precipitate Benzoic Acid
Filter Precipitate benzoic Acid ⇒ Recrystallize benzoic Acid
Phenol / Ether Extract w/ Organic Layer = Eher
10 % NaOH Aqueous Layer =
Sodium Phenolate
Sodium Phenolate ⇒ 10% HCl to precipitate Phenol Filter Precipitate Phenol ⇒ Recrystallize Phenol

Have a good day and take care.
