Chemistry Chapter 2

In blood, there are molecules which can stabilize pH. Which molecule down below can stabilize pH?

• Hydrochloric Acid

• Lactic Acid

• Carbon Monoxide

• Carbonic Acid

• Ammonia

During dissociation of most ionic compounds in water the

• positive side of water is attracted to the cation, and the negative side to the anion.

• positive side of water is attracted to both the cation and anion.

• negative side of water is attracted to both the cation and anion.

• negative side of water is attracted to the cation, and the positive side to the anion.

Covalent bonds occur when the outer orbital shells are full.

• True

• False

A neutral solution has a pH of:

• 7

• 2

• 1

• 0

• 12

Which of the following is true?

• A disaccharide has 2 or more sugars.

• Fructose is a disaccharide.

• Glucose is a disaccharide.

• A polysaccharide has 3 or more sugars.

• Sucrose is a monosaccharide.

Which is true when it comes to Ionic Bonds?

• One atom gives electrons to another so that both have filled outer orbital shells.

• Ionic Bonds do not give either electrons and protons.

• Most ionic compounds stay together when put into water.

• One atom gives protons to another so that both have filled outer orbital shells.

The number of bonds an atom can form is determined by

• the number of electrons it is missing in the outer orbital

• the number of protons it is missing in the outer orbital

• its atomic mass

• the number of neutrons it is missing in the outer orbital

• its atomic number

What is NOT an example of a Polysaccharide?

• Sucrose

• Starch

• Glycogen

• Cellulose

H+ acts as a(n)

• acid

• lipid

• enzyme

• base

• carbohydrate

The more acidic a solution is, the lesser its pH; the more basic a solution is, the greater its p

• True

• False
