One cup of fresh orange juice contains 115 mg of ascorbic acid (vitamin c, c6h8o6). given that one cup
kodGreya [7K]
The question is incomplete. Complete question is read as:
'<span>One cup of fresh orange juice contains 115 mg of ascorbic acid (vitamin C, C6H8O6). Given that one cup = 218.0 mL calculate the molarity of vitamin C in organic juice.'
..........................................................................................................................
Answer:
Given: weight of solute (ascorbic acid) = 115 mg = 0.115 g
Volume of solution = 218.0 mL = 0.218 L
Molecular weight of ascorbic acid = 176.12 g/mol.

Now, Molarity = </span>\frac{\text{weight of solute(g)}}{\text{Molecular weight X Vol. of solution(l)}}
                       = \frac{\text{0.115}}{\text{176.12 X 0.218}}
<span>                       = 0.002995 mol/dm3

Answer: Molarity of solution = </span>0.002995 mol/dm3<span>

What structural feature of lecithin allows it to behave like an emulsifying agent?
stepladder [879]
Lecithin is an emulsifier agent that's composed of 5 smaller molecules: phosphoric acid, choline, glycerol( is the backbone), and two fatty acids. 

The fatty acids, which are hydrophobic (afraid of water), makes this substance more similiar to fats and represent the non-polar part of the lecithin.
The phosphate group is the polar portion of the molecule and it's the negatively charged. The choline is positively charged, which readily dissolve in water<span>.

</span><span>Lecithin is a good emulsifier because of these structural features. the hydrophobic contacts with the oil, while the hydrophilic end contacts with the water.</span>

Which of the following elements will tend to form an anion?
JulsSmile [24]
Metals usually form cations because they like to lose electrons to get a full octet.
Nonmetals usually form anions because they like to gain electrons to get a full octet.

Aluminum will lose 3 electrons to form a cation
Beryllium will lose 2 electrons to form a cation
Copper can lose either 1 or 2 electrons to form a cation.
Silicon can gain 4 electrons to form an anion.

Your correct answer is silicon.
