A substance that contains two or more kinds of atoms is a molecule.
Number of mole : mass/ molar mass
87g/ (2 x 16) = 2.719 mol
volume = number of mole x molar volume
volume = 2.719 x 22.4
volume = 60.906 L
Answer : The balanced reduction half-reaction is:
Explanation :
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.
Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.
The given balanced redox reaction is :
The half oxidation-reduction reactions are:
Oxidation reaction : 
Reduction reaction : 
In order to balance the electrons, we multiply the oxidation reaction by 2 and reduction reaction by 3 and then added both equation, we get the balanced redox reaction.
Oxidation reaction : 
Reduction reaction :
The balanced redox reaction will be:
Thus, the balanced reduction half-reaction is:
The precipitate of reaction that occurs when silver nitrate solution is mixed with sodium chloride solution is of silver chloride (AgCI).
The chemical equation for this precipitation reaction is as following:
AgNO3(aq) + NaCl(aq) --> AgCl(s) [precipitate]+NaNO3(aq)
- Silver Chloride is a chemical compound which is poorly soluble in water because the chemical bond between Ag+ and Cl is very strong as the two ions are nearly the same size and have similar electronic densities.
- If the chemical bond is strong, it is difficult for water molecules to break this bond to surround the individual ions, thus solubility will decrease.

Answer:
B). The edges of lipid bilayers sheets fold back on themselves, forming a hollow sphere which releases the ordered waters at the edges.
C) The hydrophobic effect drives aggregation of phospholipids in an aqueous solution.
E) The cross-sectionalarea of the headgroups and acyl chains in the phospholipids are similar
Explanation:
A liposome is simply a tiny bubble also referred to as vesicle that is gotten from the same material as the one a cell membrane is made from. It should be noted that liposomes can be filled with drugs, and then used in the delivery of drugs for diseases such as cancer etc.
Phospholipids afford fluidity, permeability and stability to neural membranes. They're also vital for proper functioning of the receptors, integral membrane proteins, and the ion channels.
The characteristics of phospholipids that enable liposomes to form in water are:
• The edges of lipid bilayers sheets fold back on themselves, forming a hollow sphere which releases the ordered waters at the edges.
• The hydrophobic effect drives aggregation of phospholipids in an aqueous solution.
• The cross-sectionalarea of the headgroups and acyl chains in the phospholipids are similar
