Nitro Flashcards
Why is nitrogen gas so unreactive
-strong triple bond
- non polar
What is the shape of ammonia and the bond angle
Pyramidal and bond angle 107
In what type of reaction does ammonia react with water
Acid base
What is thw structure and bond angle in ammonium ion
Tetrahedral and bond angke 109.5
Reaction of ammonium cmpds with base
Gives salt
Ammonia
Water
What is used to dry ammonia gas
Calcium oxide
How does nitric acid form in acid rain
Nitrogen dioxide reacts with oxygen and water
Effect of unburnt hydrocarbon
Photochemical smog
Global dimming
In what does nitrogen dioxide and monoxide react with in catalytic converters
Carbon monoxide
What are the metals in a catalytic
Converter
Rhodium platinum and palladium
Why can nitrogen dioxide be described as a catalyst in the oxidation of sulfer dioxide
It increases the rate/lowers activition energy
It is chemically unchanged at the end of the reaction
Uses of ammonia
Used to make fertilisers
(Reaction with strong acids)
Used to make nitric acid
Amines are used to make nylon
Describe eutrophication
Fertilisers are leached out into rivers
Causes excessive algae growth which spread across the surface
Sun is blocked for plants at the bottom
They die
Bacteria multiply rapidly
To decay they use the oxygen dissolved in the water
Aquatic animals die due to lack of adequate oxygen
Uses of sulfer dioxide
-bleaching agent to make paper from wood pulp
-food presevative
Why is sulfer dioxide used as preservative
It is a reducing agent
It detroys unwanted enzymes and bacteria
Effect of acid rain
Corrosion of buildings
Killing aquatic life by lowering ph of water
Dissolving al3+ from soil
How to remove sulfur dioxide from waste gases (flue gas desulfurizarion)
Moist calcium carbonate
Uses of sufuric acid
Make fertilisers
Used as an electrolyte in car batteries
Contact process
Produces sulfuric acid
450
1 or 2 atm
Vanadium(5) oxide
