Answer me this:
These questions concern the following elements, which are all members of the same period of the Periodic Table: Sodium, Aluminium, Silicon, Sulphur,Chlorine
These questions concern the determination of the relative molecular mass of a liquid using the apparatus shown below
A small quantity of air was drawn into the gas syringe and the rubber cap put over the nozzle. Steam was passed through the jacket. When the thermometerreading and volume of air reached steady values these were recorded.
A small hypodermic syringe containing the liquid was weighed. The liquid was injected through the rubber cap and the syringe reweighed immediately.
When the volume of air plus vapour again reached a steady value it was recorded. The following results were obtained:
- One property of a buffer solution, prepared from a weak acid and its sodium salt, is that
[table][tr][td][size=+1]its pH is less than the pH of the original acid.
its pH is unafected by the addition of any quantity of H[sup]+[/sup] ions.
its pH is unaffected by the addition of any quantity of OH[sup]-[/sup] ions.
its pH is greater than the pH of the original acid.

When the volume of air plus vapour again reached a steady value it was recorded. The following results were obtained:
Temperature of the steam jacket = 99[sup]o[/sup]C.
Volume of air in the gas syringe = 7cm[sup]3[/sup].
Initial mass of the hypodermic syringe plus liquid = 8.36g

[table][tr][td][size=+1]Finding the mass of liquid used by weighing the gas syringe and again when the liquid has been added, instead of weighing the hypodermic syringe.
Repeating the experimental using different masses of the liquid, measuring the volume of vapour produced each time and then using these results graphically to determine the density of the vapour.
Omitting the air from the gas syringe.
Using a smaller mass of the liquid.
Heating the gas syringe with an electric light bulb instead of using steam.[/size][/td] [td][/td] [/tr][/table]- A similar experiment at 130[sup]o[/sup]C using ethanoic acid, CH[sub]3[/sub]CO[sub]2[/sub]H, as the liquid gave a value for its relative molecular mass of 120 instead of the expected value of 60.
An explanation for this result could be that under the conditions of the experiment
[table][tr][td][size=+1]the volume of the ethanoic acid molecules is NOT negligible in comparison with the total volume of the vapour.
ethanoic acid vapour exists in the form of the dimer (CH[sub]3[/sub]CO[sub]2[/sub]H)[sub]2[/sub].
the molecule of ethanoic acid partially dissociates CH[sub]3[/sub]CO[sub]2[/sub]H[sub](g)[/sub]š H[sup]+[/sup][sub](g)[/sub] + CH[sub]3[/sub]CO[sub]2[/sub][sup]-[/sup][sub](g)[/sub]

[h2]Questions 41 to 45[/h2]

[table][tr][td][size=+1]It indicates when the silver halide has been precipitated.
It prevents the immediate precipitation of the silver halide.
It acts as an electrophile.

Which of the following best explains these results?
[table][tr][td][size=+1]The solubility products of the silver halides decreases as you go down the halogens from chlorine to iodine.
