Answer: Products have a higher total potential energy than the reactants.
Explanation:
During endothermic reactions, energy is absorbed, meaning that the products will have more potential energy.
Answer : S) 33.2 °C
Explanation : When the equal amounts of gases are placed in identical containers but subjected to different temperatures would exert pressure in different amount which will in turn increase the rate of collision between the molecules of gas.
So, when the temperature is increased to maximum greater amount of force would be exerted and the gas molecules will collide with a larger force. Hence the answer will be as the highest temperature i.e. 33.2 °C
The right answer is Hydrogen bonds with the polar end of the phospholipid molecule.
A phospholipid contains a phosphoric acid group as mono or di-ester.
The physicochemical properties of phospholipids depend both on the polar molecule of the hydrophilic head and on the aliphatic chains of the hydrophobic tails. In an aqueous medium, such amphiphilic molecules tend to be organized so that only their hydrophilic head is in contact with the water molecules, which typically results in structures in micelle, liposome or lipid bilayer.
