CHEMISTRY.-PART I.

The Board of Examiners.

1. State the law of Dulong and Petit.

The specific heats of tin, nickel, and lead are respectively .055, 108, and 031; and the atomic weight of tin is 118. Calculate the approximate atomic weights of nickel and lead.

2. Give the equation for the action of hot sulphuric

acid on calcium oxalate.

Calculate the total volume of gas (at standard conditions) obtainable by the above reaction from that quantity of the oxalate which would, if strongly heated by itself, yield 14 grammes of quick-lime. [Given that the atomic weight of calcium is 40, and that one gramme of hydrogen,

at standard conditions, occupies 11:16 litres.] 3. Give a short account of the occurrence, composition,

properties, and chief practical applications of any three of the following substances :-(a) Nitre, (6) fluorspar, (c) green vitriol, (d) pyrolusite,

(e) galena. 4. Compare and contrast phosphorus and arsenic,

having regard to the elements themselves and also their chief compounds.

5. Explain fully the following facts :(a) The yellow sulphide of tin is soluble in yellow

ammonium sulphide solution.

(6) The brown sulphide of tin is insoluble in

colourless, but soluble in yellow, ammonium
sulphide solution.

6. A gas is prepared by the action of hydrochloric

acid on marble, and is dried by passing through
sulphuric acid; it is then led slowly through
a tube containing red-hot charcoal; thence
through a second tube containing red-hot cupric
oxide; and finally into a bottle containing cal-
cium hydroxide solution. Describe fully all the
changes that occur, and give equations.

7. Describe what happens in each of the following

cases, and give equations where possible:(a) Sodium acetate is heated with sulphuric acid. (6) Sodium acetate is heated with sulphuric acid

and alcohol. (c) Sodium acetate solution is submitted to electro

lysis. (d) A mixture of solid sodium acetate and sodium

hydroxide is heated to redness.

A, B, and respectively. Pay particular atten

tion to the preliminary and blowpipe examination. Give a full written report of your work, arranging it

in_three parallel columns headed respectively “Experiment,” “Result,” “Inference.”

a

Only such abbreviations may be employed as are in general use among chemists.

No credit will be given for a correct result unless correct and sufficient reasons be given in support of it.
