| Oxides of Carbon | Oxides of Nitrogen | Oxides of Nitrogen (Continued) | Oxides of Sulphur | True or False |
|---|---|---|---|---|
|
Carbon forms two types of oxides, carbon monoxide ‘CO’ and carbon dioxide ‘CO 2’ Also it forms carbon suboxide, C3O2. Carbon monoxide is produced when one of the naturally occurring forms of elemental carbon is heated or burned in a limited amount of oxygen.
What is Oxides of Carbon?
|
Aquatic
What environment is the ecological effects of acid rain most seen in?
|
Photochemical smog
Nitrogen oxides play a huge role in creating what formation?
|
Aluminium metal has a strong affinity for oxygen and the oxide of Al is Al2O3, which is a very stable oxide. Hence ordinary chemically reducing agents are not sufficient to reduce Al2O3 to Al. Electrolytic reduction is a more powerful reduction method.
Why is Al obtained only by electrolytic reduction of Alumina?
|
True
Atoms are composed of electrons, protons, and neutrons.
|
|
Human sources come from activities like cement production, forest fire as well as the burning of fossil fuels like coal, oil and natural gas.
What are some man made sources from Oxides of Carbon?
|
-163.6 and -151.8
What is the melting point and boiling point?
|
A heavily polluted one
What kind of environment does acid deposition make?
|
The two commonly used ores of zinc are zinc blende (ZnS) and calamine (ZnCO3)
Name the two ores of zinc that are commonly used
|
False
Ionic bonds occur between either 2 positive or 2 negative atoms
|
|
Radiatively active gases absorb specific wavelengths of radiation. Very little radiation is absorbed in the visible wavelengths, between about 0.4 and 0.75 micrometers.
What kinds of radiation pass through the atmosphere?
|
Irritated eyes, nose, throat and lungs. Coughing, tiredness, shortness of breath and nausea
Side effects of breathing in the nitrogen oxides?
|
Process of burning coal and fossil fuels
What is one way Nitrogen Oxides are created?
|
Gold and Platinum are two metals that occur in a free in state in nature
Name two metals that occur in a free state nature?
|
True
In a covalent bond, atoms share outermost electrons to achieve stability.
|
|
Clouds absorb a lot of outgoing (infrared) radiation, and reradiate it back down to earth. On nights when clouds are nonexistent, much less radiation comes back to us and more goes through the atmosphere out to space.
Why do clear winter nights tend to be colder than cloudy ones?
|
N2 + 8H + 8E = 2NH3 + H2
What is the chemical reaction?
|
Carpool, walk, bike, reduce electrical use around your house
How to decrease the pollution this creates?
|
They only need to be cleaned by physical methods.
What is the method of refining them?
|
True
Glucose is a molecule made up of C, H, and O atoms joined together by chemical bonds.
|
|
Yes, but the problem in separating the carbon and oxygen from CO2 is that CO2 is a very stable molecule, because of the bonds that hold the carbon and oxygen together, and it takes a lot of energy to separate them.
Is it possible to separate the carbon and oxygen from CO2 as is possible with other molecules?
|
Wildfires and lightning storms and then cigarettes smoking, heating and exhausts
What are 2 natural sources? What are 2 man made sources?
|
Nutrients and minerals
What does acid rain remove from soil?
|
Antoine Lavoisier
Who convinced the Science community that Sulphur was an element?
|
True
The first biogeochemical cycle to be discovered was the Sulphur cycle
