Find number of moles and divide by volume to get molarity
Kepler's Laws of Planetary Motion. While Copernicus rightly observed that the planets revolve around the Sun, it was Kepler who correctly defined their orbits.

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
Answer:
A. 
B. 
Explanation:
Hello!
In this case, since the undergoing chemical reaction between nitrogen and hydrogen is:
Thus we proceed as follows:
A. Here, we first need to compute the moles of ammonia yielded by each reactant, in order to identify the limiting one:
Thus, since nitrogen yields the fewest moles of ammonia, we realize it is the limiting reactant, so the theoretical yield, in grams, of ammonia is:
B. Finally, since the actual yield of ammonia is 1.23, the percent yield turns out:
Best regards!
