Questions & Answers | Chamberlain College of Nursing |
Graded A+
1. The defining equation for density is:
D= volume/mass
D= mass x volume
D= volume x mass
D= mass/volume
none of the above
2. If you were to synthesize an ether from an alcohol, which reaction would you
likely use?
Hydrolysis reaction
Hydrogenation reaction
Dehydration reaction
Oxidation reaction
3. Describe the difference between saturated and unsaturated compounds in
organic chemistry.
Saturated compounds have a higher boiling point than unsaturated
compounds.
Saturated compounds contain only single bonds, while unsaturated
compounds have one or more double or triple bonds.
Saturated compounds are always gases, while unsaturated
compounds are liquids.
, Saturated compounds can only be alkanes, while unsaturated
compounds can be alkenes or alkynes.
4. In a neutralization reaction between sodium and hydroxide, NaOH, and
hydrochloric acid, Hcl, the salt produced would be:
sodium hydrochloride
sulfuric acid
sodium chloride
sodium oxide
5. Describe the characteristics of a covalent bond and how it differs from an
ionic bond.
Covalent bonds occur only in organic compounds, while ionic bonds
occur in inorganic compounds.
Covalent bonds are weaker than ionic bonds due to the lack of
electron sharing.
A covalent bond involves the complete transfer of electrons, whereas
an ionic bond involves sharing.
A covalent bond is formed by the sharing of electron pairs between
atoms, while an ionic bond is formed by the transfer of electrons
from one atom to another.
6. If a gas occupies a volume of 4 liters at a pressure of 1 atmosphere, what will
be the pressure if the volume is reduced to 2 liters while keeping the
temperature constant?
0.5 atmospheres
4 atmospheres
1 atmosphere
, 2 atmospheres
7. Describe the role of acids in chemical reactions and what they contribute to
the reaction.
Acids form covalent bonds with other molecules to stabilize them.
Acids donate electrons to other compounds, facilitating oxidation.
Acids donate protons (H+) in chemical reactions, which can affect
the pH and reactivity of the solution.
Acids provide energy to the reaction by releasing heat.
8. Which of the following is an example of an aldehyde?
CH3C=OOCH3
CH3CH2OH
CH3COOH
CH3CHO
9. Describe the composition of sodium nitrate and its significance in chemistry.
Sodium nitrate contains sodium and sulfate ions, commonly used in
food preservation.
Sodium nitrate consists of sodium and nitrite ions, important for
protein synthesis.
Sodium nitrate is composed of sodium ions (Na+) and nitrate ions
(NO3-), and it is significant as a source of nitrogen in fertilizers.
Sodium nitrate is made of sodium and ammonium ions, used primarily
in explosives.
, 10. In a laboratory experiment, you mix hydrochloric acid with sodium
hydroxide. What products do you expect from this reaction?
Sodium and chlorine gas
Hydrogen gas and sodium chloride
Sodium hydroxide and hydrochloric acid
Water and sodium chloride
11. Sodium nitrite is an antimicrobial salt used in the production of bacon and
salami. What is the chemical formula of sodium nitrite?
Na2NO2
Na2NO4
NaNO3
NaNO2
Na2NO3
12. Describe the significance of the ideal gas law in understanding gas behavior.
The ideal gas law is only applicable to noble gases.
The ideal gas law only applies to gases at high pressures and low
temperatures.
The ideal gas law relates pressure, volume, temperature, and the
number of moles of a gas, allowing predictions about gas behavior
under various conditions.
The ideal gas law explains the behavior of solids and liquids under
pressure.
