Stearic acid, a fatty acid commonly found in animal fat, has a condensed chemical formula of ch3(ch2)16cooh. it is a common component of soaps and detergents. which statement below is false? stearic acid would probably dissolve in nonpolar solvents such as hexane, c6h14. the long alkane "tail," ch3(ch2)16−, is hydrophobic. stearic acid contains hydrophilic and hydrophobic regions. the –cooh group would experience hydrogen bonding with water. stearic acid and water are probably miscible.

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.

Moles = mass/molar mass by this formula 458/207+32 you should get your answer the ans. is 1.916 mol to 4 sig. fig.

Heat capacity = mcδtheat capacity = 2.676×10^3 j ..the heat capacity given is for 7.00 g of kcn,potassium cyanide which is equal to 0. mole of mole = mass  ÷ mr of kcn is 7  ÷ 65 =0.therefore: 0. of kcn liberates 2.676×10^3 j of heat1 mole   (2.676×10^3    ÷  0.107 )  × 1 =do the calculation to obtain 25009 j = 25kj
