Examples of renewable resources are what? |
Plants and Animals |
|
|
Renewable Resources means what? |
They can be replaced in a short period of time. It can replenish by natural process at a rate comparable or faster than its rate of consumption, by humans or other users. |
|
|
Natural Resources qualify as what? |
Renewable Resources |
|
|
Examples of Natural Renewable Resources are what? |
Fresh Water, Timber, Paper, Leather, and Biomass |
|
|
What do you have to be aware of with Natural Renewable Resources? |
Carefully managed to avoid exceeding the environment's capacity to replenish |
|
|
Non-Renewable Resources are what? |
Natural Sources that cannot be produced, re-growth, regenerated,or reused on a scale which can sustain its consumption rate |
|
|
Examples of Non-Renewable Resources are what an include what main things? |
Non-Renewable Resources are things such as Coal, Petroleum, Natural Gas, and Nuclear Fuel Non-Renewable Resources include main things such as Minerals and Fossil Fuel |
|
|
Inexhaustible Resources means what? |
Will never run out |
|
|
Examples of Inexhaustible resources are what? |
Wind, Solar, and Geothermal energy |
|
|
Resources like the sun what? |
Cannot be used up by humans |
|
|
Line Graphs illustrate what? |
Relationship of two quantitative varaibles |
|
|
Bar Graphs compare what pieces of data? |
Individual pieces of data |
|
|
Pie and Circle Graphs best display what? |

Interpolation is what? |
Inferring data between measured points |
|
|
Extrapolation is what? |
Predicting data beyond the measured points |
|
|
Between Extrapolated and Interpolated data which one is not more reliable and why? |
Extrapolated data is not reliable because many variables can affect future results |
|
|
A chemical reaction produces what? The result is what of an imperfect burn? |
Imperfect burn is produced Carbon Monoxide is the result( Harmful Substance) |
|
|
What is the difference between a perfect and imperfect burn? |
Perfect burn requires more oxygen than an imperfect burn. In a perfect burn, all of the hydrocarbons are used up and no harmful chemicals are produced, but in an imperfect burn it produces Carbon Monoxide, which is a deadly gas, and some of the hydrocarbons is left over and is known as Carcinogen or a cancer- causing agent |
|
|
What is the formula for a perfect burn? |
CxHy+O2=(yeild sign) CO2+H2O |
|
|
What is the formula for an imperfect burn? |
CxHy+O2(2 is a subscript)=(yield sign)CO2+H2O+CO+CxHy |
|
|

A chemist and a teacher who used the burner for his research in isolating chemical substances
|
|
|
Gustav Kirchhoff developed what? He discovered what? |
He developed spectral anyalysis of chemicals and discovered the elements Rubidium and Cesium |
|
|
Bunsen is resopnsible for what? What was the Result? |
Improving the designs of the burner. So as a result the piece of equipment was named after him. |
|
|
Bunsen Burner is commonly used as what? Bunsen Burner is used why? It is also used to what? |
Labotaory equipment. For heating substances when an intense heat source is needed. Control a flame produced from the lightning and burning of natural gas. |
