Questão 2
Questão
What 3 GASES do volcanoes give out?
Questão 3
Questão
What happened to the atmosphere when plant life formed?
Responda
-
There was less CO2 in it and more O2 because as the plants went through PHOTOSYNTHESIS they converted the Carbon Dioxide into Oxygen.
-
Nothing happened, the atmosphere stayed the same.

Questão 8
Questão
What/How does CARBON MONOXIDE, SULFUR DIOXIDE and CARBON DIOXIDE do/effect people and the planet?
Responda
-
Carbon Monoxide- Cuts off the Oxygen supply your blood cells carry. (DIRECT HARM)
Sulfur Dioxide- Causes Acid rain which kills fish which people eat (INDIRECT HARM)
Carbon Dioxide- part of Climate Change which is caused by Pollution and creates World Problems. (INDIRECT HARM)
-
Carbon Monoxide- Given out by Cows and it the cause of Global Warming (INDIRECT)
Sulfur Dioxide- Stains buildings and burns skin when it falls as from the sky as rain and soot (INDIRECT)
Carbon Dioxide- Kills people and the planet (DIRECT)
Questão 9
Questão
In chemical reactions, can atoms disappear?
Responda
-
Yes, because some are lost because the just get lost
-
No, because the end product always has the same amount of each atom in and no mass is lost which also proves no atoms are lost because if they were the mass would be less.

-
A Carbon Atom that has been pressurised with Hydrogen to form dead plant cells

Absorbed into Rivers, Lakes and other forms of water
-
High powered air suction
Carbon extracting

Questão 14
Questão
Nitrogen Pollution is formed from nitrogen in the air when Fuel is burnt. Name both Nitrogen Oxides (NOx) and an example of when they form and are released?
Responda
-
Nitrogen Dioxide, Nitrogen Monoxide and Car Engines

Questão 15
Questão
Although we produce a lot of pollution there are ways to reduce the amount we make. Name one place we can reduce pollution from, a way in which cars now lower there emission and two alternate energy sources?
Responda
-
Power Stations (Remove the sulfur from burning materials and reduce amount of Fossil Fuels used), Cars are not fitted with Catalytic Converters which converts Nitrogen Monoxide in harmless Nitrogen and Oxygen, and finally Wind Power (Turbines) and Solar Panels.
