|---|---|---|---|---|---|
| Write a word equation to show the combustion of Pentane (a chemical found in crude oil) | show 🗑
|
||||
| show | C5H12 + 8 O2 --> 5 CO2 + 6 H2O (always start by writing the word equation! Then formulae! Then balance)
🗑
|
||||
| show | Carbon Dioxide and Methane
🗑
|
||||
| Describe how the Greenhouse effect warms the Earth | show 🗑
|
||||
| CHALLENGE: what happens to greenhouse gases when they absorb infrared radiation? | show 🗑
|
||||
| Why are scientists worried that the levels of Carbon Dioxide are increasing? | show 🗑
|
||||
| What is the evidence that increased levels of CO2 cause the Greenhouse effect? | show 🗑
|
||||
| What is the evidence that increased levels of CO2 does NOT cause the Greenhouse effect? | show 🗑
|
||||
| show | 1)rising sea levels; 2)extreme weather pattern 3)changes to climate (amount and timing of rainfall) that may lead to species being wiped out
🗑
|
||||
| show | The amount of Carbon Dioxide and other Greenhouse gases produced by an activity
🗑
|
||||
| show | When Carbon Dioxide is trapped, then pumped deep underground in porous rocks, or deep under the ocean
🗑
|
||||
| Describe a few measures that the Government can take to reduce the levels of CO2 | show 🗑
|
||||
| show | Fuels made from plants; when the next crop of plants grows, it absorbs the CO2 emitted by the combustion of the first crop
🗑
|
||||
| Describe a few things that You could do to reduce your carbon footprint | show 🗑
|
||||
| show | When the products of combustion are carbon dioxide and water only
🗑
|
||||
| What is incomplete combustion? | show 🗑
|
||||
| show | Carbon Monoxide binds stronger to the Haemoglobin in the red blood cells; and prevents Oxygen from binding; as Oxygen is not transported anymore, cells are unable to produce energy and die.
🗑
|
||||
| Why does incomplete combustion take place? | show 🗑
|
||||
| show | When Sulfur IMPURITIES in the fossil fuels burn in Oxygen
🗑
|
||||
| show | Sulfur Dioxide reacts with water to form Sulfuric Acid
🗑
|
||||
| What is the consequence of acid rain | show 🗑
|
||||
| show | neutralise the sulphur dioxide in factories chimneys by reacting the sulphur dioxide with calcium oxide; also by removing sulphur from fossil fuels
🗑
|
||||
| How do cars produce Nitrogen Oxides? | show 🗑
|
||||
| Is this equation balanced? CH4 + O2 --> CO2 + H2O | show 🗑
|
||||
| show | CH4 + 2 O2 --> CO2 + 2 H2O
🗑
|
||||
| What is the formula of Methane? | show 🗑
|
||||
| What is complete combustion? | show 🗑
|
||||
| show | Carbon Dioxide and Water
🗑
|
||||
| show | Soot, Carbon Monoxide and Water
🗑
|
||||
| What is the Hazard of Carbon Monoxide? | show 🗑
|
||||
| show | CO
🗑
|
||||
| show | CO2
🗑
|
||||
| show | Sulfur
🗑
|
||||
| show | Acid Rain
🗑
|
||||
| show | Greenhouse effect
🗑
|
||||
| show | Sulphur Dioxide
🗑
|
||||
| What gas is causing the Greenhouse effect? | show 🗑
|
||||
| show | Volcanic eruption
🗑
|
||||
| Name a human activity that produces Carbon Dioxide | show 🗑
|
||||
| Why is there more Carbon Dioxide in Winter than in summer? | show 🗑
|
||||
| What is the evidence that humans are responsible for causing the Greenhouse effect? | show 🗑
|
||||
| show | Levels of CO2 have risen up and down for millions of year.
🗑
|
||||
| Name 2 things that chemists are trying to do to remove CO2 from the atmosphere | show 🗑
