Nature's Chemistry - Processes and Other Details Flashcards
What is the chemical equation for Respiration?
Glucose + Oxygen → Carbon Dioxide and Water
C₆H₁₂O₆ + 6O₂ → 6CO₂+ 6H₂O
What is the chemical equation for the combustion of fuels/hydrocarbons?
Hydrocarbon (Fuel) + Oxygen → Carbon Dioxide + Water
Name all of the equipment used inthe process of fractional distillation
- Thermometer
- Fractioning column
- Round-Bottom flask
- Bunsen Burner
- Condenser
- Recieving Flask
What is the word eqaution for the combustion of ethanol?
ethanol + oxygen → water + carbon dioxide
(C₂H₅OH + O₂ → H₂O + CO₂)
What is photosynthesis?
It is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.
What is respiration?
Respiration is a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide.
What is the chemical symbol for glucose?
C₆H₁₂O₆
Why is glucose NOT a hydrocarbon?
Glucose is a carbohydrate (composed of carbon, hydrogen and oxygen) and hydrocarbons are composed of ONLY carbon and hydrogen
Why are lager and beer fizzy?
The CO₂ produced is a gas
What is the chemical symbol for ethanol?
C₂H₆O
What is the chemical equation for fermentation?
C₆H₁₂O₆ → CO₂ + C₂H₅OH.
glucose + enzymes → carbon dioxide + ethanol/lactic acid.
Describe the process of Fermentation
Fermentation is the breaking down of sugar molecules into simpler compounds to produce substances that can be used in making chemical energy.
What is the chemical equation for photosynthesis?
(what do you also notice?)
Carbon dioxide + Water → Glucose + oxygen
6CO₂+6H₂O→C₆H1₂O₆+6O₂
This is respiration backwards
