1. The contact process is the general name given to the series of reactions leading up to the creation of H2SO4 or sulphuric acid. One of the steps is the oxidation of sulphur. Structurally speaking, what does oxidation mean? Gaining Electrons None of these Electronic configuration remains the same Losing Electrons

2. Another part of the contact process is the creation of fuming sulphuric acid. What is the chemical term for this substance? Pyruvate Oleum Mallium Cantra

3. A catalyst is a substance that speeds up a chemical reaction without reacting itself. In the contact process, a catalyst is used in one of the middle steps, during the creation of sulphur trioxide. Which of the following catalysts would it be? Magnesium Sulphate Iron (III) Bromide Vanadium (V) Oxide Hydrochloric Acid

4. Another industrial process is used to create ammonia gas. What is this process called? The Randolph Process The Haber Process The Fumigation Technique The Boston Technique

5. There are two raw materials used in the creation of ammonia gas. The first material is nitrogen. Nitrogen gas (N2) has a very strong triple bond between its two molecules and is found, abundantly in our atmosphere. It constitutes just below 80% of the total gas found in the air. This is reacted to another gas - which? Helium Oxygen Hydrogen Argon

6. The production of ammonia is efficient in the fact that the unused gases are recycled back into the process. How are these unused gases separated from the ammonia? Liquification Burning Solidification Smelting

7. A very interesting chemical process is the creation of molten iron in the blast furnace. Many raw materials are used in this process. What is the name of the ore which contains the wanted iron? Bauxite Haematite Malachite Gypsum

8. Hot air is pumped into the blast furnace which reaches very high temperatures. The hot air contains oxygen and reacts with carbon to form carbon dioxide and eventually reacts further to form the poisonous carbon monoxide. Carbon monoxide (CO) is a reducing agent and helps to extract iron from its ore. Where does the carbon originally come from? Fertiliser None of these Manure Coke

9. In the production of molten iron, lime is a material that needs to be added to the blast furnace. What is the purpose of adding this substance? Removes unwanted carbon Removes all acidic impurities Reduces temperature of the iron To be used as a catalyst

10. The molten iron sits at the bottom of the blast furnace waiting to be siphoned off. What is the name of the substance which rests on top of it? Heap Slag Pure Water Pure Calcium
