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?
Electronic configuration remains the same
None of these
Another part of the contact process is the creation of fuming sulphuric acid. What is the chemical term for this substance?
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?
Iron (III) Bromide
Vanadium (V) Oxide
Another industrial process is used to create ammonia gas. What is this process called?
The Boston Technique
The Randolph Process
The Haber Process
The Fumigation Technique
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?
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?
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?
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?
None of these
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?
To be used as a catalyst
Removes unwanted carbon
Removes all acidic impurities
Reduces temperature of the iron
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?
