Question
19) Hydrogen bonds also allow water to form hydrogen bonds with different like salts and sugars. What property of water is a result of this interaction? molecules 20) Hydrogen bonds allow water molecules to form a linked network with each other. What two properties of water are dependent on this bonding between water molecules? 21) What is a neutral, basic, and acidic pH? 22) When do acids and bases get stronger? 23) Why would you drink milk after ingesting bleach? 24) What makes a molecule organic? 24) Explain why oils and water not mix? Be sure to mention polar and nonpolar 25) Contrast a dehydration synthesis reaction and a hydrolysis reaction. 26) List the polymers of each organic group. 27) How is sucrose classified specifically? What type of reaction builds this molecule? JamesExplanation / Answer
19.
Water is a polar molecule.
The polarity of the O-H bond in water molecule is responsible for its H-bonding ability.
20.
H-bonding allows the strong association between water molecules. This is responsible for
1. Its high boloing point
2. High melting point
3. High specific heat
21.
Neutral pH =7
Acidic pH < 7
Basic pH > 7
22.
The strength of an acid depends upon high efficiently it can donate H+ ion.
The strength of base depends upon high efficiently it can accept H+ ion.
23.
Drinking milk dilutes the bleach and reduces its harmful effects.
The basic nature of milk and lactose sugar are responsible for this property.
Lactose slows down the absorption of bleach in the intestine.
