State the Ideal Gas Equation, what each symbol represents and
the units for each symbol. [9] - CORRECT ANSWER-PV= nRT
where...
P= Pressure measured in Pa
V= Volume measured in m³
n= number of moles
R= The molar gas constant- 8.31JK^-1mol^-1
T= Temperatures measured in K
Define Empirical Formula [1] - CORRECT ANSWER-The simplest
whole-number ratio of atoms of each element in a compound.
Define Molecular Formula [1] - CORRECT ANSWER-The actual
number of atoms of each element in a compound.
What are the four state symbols? [4] - CORRECT ANSWER-Solid (s),
liquid (l), gas (g), aqueous solution (aq)
,Describe how to perform a titration. [5] - CORRECT ANSWER-1. Fill a
burette with the acid of known concentration,
2. Accurately measure 25cm³ of the alkali solution using a
pipette and transfer it to a conical flask.
3. Add a few drops of a suitable indicator to the alkali. eg
phenolphthalein.
4. Slowly add the acid from the burette into the conical flask,
swirling constantly. As soon as the indicator changes colour the
solution has turned neutral so stop adding the acid.
5. Record the volume of acid added.
6. Repeat the process until you achieve concordant results. The
mean of these results is used to calculate the average titre.
State the formula for percentage atom economy. [1] - CORRECT
ANSWER-
State the formula for percentage yield. [1] - CORRECT ANSWER-
Describe how to make up a standard solution [7] - CORRECT
ANSWER-1. Weigh the sample bottle containing the solid on a
balance.
2. Transfer solid to a beaker and reweigh the sample bottle.
3. Record the difference in mass.
4. Add distilled water and stir with a glass rod until the solid
has dissolved.
5. Transfer to a volumetric flask with washings.
6. Makeup to the 250cm³ mark with distilled water.
7. Shake flask.
, What is an ionic bond? [1] - CORRECT ANSWER-The strong
electrostatic attraction between oppositely charged ions.
Describe the melting and boiling point of an ionic compound.
[3] - CORRECT ANSWER-- Strong electrostatic attraction between
ions.
- This requires a lot of energy to overcome.
- Giving ionic compounds high melting and boiling points.
Describe the electrical conductivity of an ionic compound. [3] -
CORRECT ANSWER-- Can conduct electricity when molten or in
solution.
- When compound is solid the ions are held in fixed position
and cannot flow.
- When compound is molten/in solution, the ions are free to
move and carry charge.
Describe the structural properties of an ionic compound. [2] -
CORRECT ANSWER-- Brittle, shatter easily.
- As if the rows of ions slide past one another and like charges
are adjacent, the two fragments repel one another.
What is meant by covalent bond? [1] - CORRECT ANSWER-A shared
pair of electrons between two atoms.
Why do covalent substances not conduct electricity? [1] -
CORRECT ANSWER-Electrons used in forming covalent bonds and
cannot carry charge.
