Combustion Flashcards
What is an example of a fuel cell?
Hydrogen
What are hydrogen fuel cells?
Hydrogen fuel cells produce energy/electricity by combining hydrogen with oxygen atoms and then running it
What is fuel
is a chemical substance from which the stored energy can be transferred to use useful new energy
What is a fuel cell?
A fuel cell produces energy through chemical reaction that happened with oxygen
What is combustion
Combustion is a chemical reaction in which a substance reacts rapidly with oxygen and gives off energy in the form of heat and light (Also known as burning)
What is oxidation?
Oxidation is when oxygen is being added to a different substance or element
What’s the difference between an atom and a molecule?
An atom has one element in it and a molecule has a group of atoms which is 2 atoms
If a mass of 2.4g of magnesium is burnt in Air and 4.0 magnesium oxide is produces
What type of reaction is this?
Oxidation
What does a fire need to burn or catch on fire
oxygen, fuel, and heat
What is the essential ingredient for fire to keep
blazing
oxygen
What is the Law of conservation of mass?
no atom can be created or destroyed only rearranged into a fixed ratio
what is the formula for methane with oxygen?
CH4 + 2 O2 = CO2 2h2o
What could have been the start of a reaction to make the hummingbird exploded
A spark of flame could have started it
