Study Guide: Chapter 31. What are the four emergent properties of water that contribute to Earth’s sustainability forlife? Explain each property in your own words.a. Cohesive behaviori. Cohesion- water bonding to waterii. Adhesion- water bonding to something else (water in plant cells)b. Ability to moderate temperaturei. Water has a high specific heat (it takes a lot of energy to break the hydrogen bonds)ii. Why can water absorb or energy a lot of heat without changing?1. The molecules ability to move is limited by the hydrogen bonds, therefore resisting a lot motion which resists changes in temperature.c. Expansion upon freezingi. Why is water less dense as a solid?1. The hydrogen bonds in ice are more ordered, with little motion which causes the bonds to stretch out a little make more space between molecules, making ice less dense.ii. Density= mass/volume1. Ex: Density of liquid= 100/10= 10 Density of solid=100/20= 5 (takes up more space but has same about of molecules so they are spread out)d. Versatility as a solventi. Hydration shell- When an ionic compound is dissolved in water, each ion is surrounded by a sphere of water molecules called a hydration shell.2. The four properties of water are attributed to what characteristic of water?3. A single water molecule can bond with how many other water molecules? What type of bond holds a water molecule together and what type of bond is formed between these water molecules?4. How are plants able to transport water against the pull of gravity?5. Why can some small insects walk on the surface of water? Surface tension6. Why is it important that water has a high specific heat?7. Why does water make such a versatile solvent? 8. What does it mean if a molecule is hydrophilic or hydrophobic?9. What are the properties of acids and bases?10. If the Hydrogen ion concentration of a solution is 10-3, what is the pH of the solution?11. What is the relationship between pH and [H+]?12. What is the pH scale? What pH values indicate an acidic solution, a basic solution, and a neutral solution?13. Molecular mass- (Daltons) mass multiplied by amount.a. C6= (12 Da x 6)= 72 Da14. Molarity= (# of moles)/(volume in liters)a. M= (1 mole of Glu)/(1 L of H2O)= 1M solution (180g in 1L)15. What is the molecular mass of NH3? Show your work16. How many molecules make up one mole of NaCl?17. What is the mass of one mole of
