Oxides of Carbon Oxides of Nitrogen Oxides of Nitrogen (Continued) Oxides of Sulphur True or False
100
What is Oxides of Carbon?
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.
100
What is the melting point and boiling point?
-163.6 and -151.8
100
What kind of environment does acid deposition make?
A heavily polluted one
100
Why is Al obtained only by electrolytic reduction of Alumina?
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.
100
Atoms are composed of electrons, protons, and neutrons.
True
200
What are some man-made sources?
Human sources come from activities like cement production, forest fire as well as the burning of fossil fuels like coal, oil and natural gas.
200
Side effects of breathing in the Nitrogen Oxides?
Irritated eyes, nose, throat and lungs. Coughing, tiredness, shortness of breath and nausea
200
What’s one way Nitrogen Oxides are created?
Process of burning coal and fossil fuels
200
Name the two ores of Zinc that are commonly used
The two commonly used ores of zinc are zinc blende (ZnS) and calamine (ZnCO3)
200
Ionic bonds occur between either 2 positive or 2 negative atoms.
False
300
What kinds of radiation pass through the atmosphere, and what kinds are absorbed?
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.
300
What is the chemical reaction?
N2 + 8H + 8E = 2NH3 + H2
300
How to decrease the pollution this creates?
Carpool, walk, bike, reduce electrical use around your house
300
Name two metals that occur in a free state nature.
Gold and Platinum are two metals that occur in a free in state in nature.
300
In a covalent bond, atoms share outermost electrons to achieve stability.
True
400
Why do clear winter nights tend to be colder than cloudy ones?
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.
400
What are 2 natural sources? What are 2 man made sources?
Wildfires and lightning storms and then cigarettes smoking, heating and exhausts
400
What does acid rain remove from soil?
Nutrients and minerals
400
What is the method of refining them?
They only need to be cleaned by physical methods.
400
Glucose is a molecule made up of C, H, and O atoms joined together by chemical bonds.
True
500
Is it possible to separate the carbon and oxygen from CO2 as is possible with other molecules?
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.
500
Nitrogen oxides play a huge role in creating what formation?
Photochemical smog
500
What environment is the ecological effects of acid rain most seen in?
Aquatic
