What must be present for combustion to occur?
heat, fuel, and oxygen
Why is 2 Mg O2 equals 2 MgO is not a combustion reaction?
Because combustion reactions only occur with Carbon, Hydrogen, and Oxygen.
What is present within the mitochondrion that allows the reaction to occur?
ENZYMES
What might the result be if one particular enzymes malfunctioned or was not present?
the reaction would be slower or it may not occur at all
Which element is required for a combustion reaction to occur?
Oxygen? no, nitrogen is an odourless and colourless diatomic gas which can be used to support combustion.

What does force always do?
Forces always occur in pairs. They even have reaction force pairs occur when there is no motion
What is needed for combustion to take place?
A combustion reaction takes place when a fuel and an oxidant react, producing heat or heat and light. The most recognizable form of combustion reaction is flame, with explosions being an even faster form of combustion reaction. A combustion can happen at a wide range of speeds, and can occur in many different environments, but the majority of combustions we know and recognize happen in a fairly limited spectrum.
Which type of reaction takes place in the presence of oxygen and produces carbon dioxide and water?
A chemical reaction where one of the reactants is O2 and one of the products is water is called a combustion reaction. Combustion reactions generally take the form: __CxHx + __O2 --> __H2O + __CO2 + energy
Does combustion occur when lighting a match in the air?
Yes, combustion is simply the chemical reaction of a substance with oxygen molecules. In this case the match and match head are reacting with the ocygen int he air.
What does forces do?
Forces always occur in pairs. They even have reaction force pairs occur when there is no motion
What does the complete combustion of coal produce?
The complete combustion of organic compounds produces Carbon Dioxide (CO2), Water (H2O), and a residue of any impurities which were present in the coal before combustion. Complete combustion requires a great surplus of molecular Oxygen to occur.
Do action-reaction forces always occur in threes or pairs?
Pairs!
Why is it so important for the ignition process to occur in a gasoline car?
For a combustion engine to work, it must have the following: Air Fuel Ignition if any of the above are not present, combustion cannot take place.
