What molecule caused the flame to go out when a jar was placed over it?
CO2 as there was no more oxygen in the jar.
The process of burning something.
Combustion
What are the steps of energy exchange in a vehicle?
1. Energy is first stored in the fuel and released when burnt.
2. Burning of fuel pushes the piston done.
3. Piston movement causes crankshaft to turn
4. Crankshaft spins the transmission
5. The transmission causes the drive shaft to rotate
6. Driveshaft spins the differential which in turns spins the axels needed for the wheels.
What is the coefficient in a chemical reaction?
It tells you how many different molecules are involved in the reaction.
When I ask "what is the relationship of this graph", what am I asking?
