You have to use everything that is given since you have to know which is the limiting reactant. We find the limiting reactant by calculating the number of moles of each reactant and compare the number of moles. The limiting reactant would be the one that is consumed fully by the reaction.
The answer is double displacement is the answer
The driving thrust of the car produced by the engine is the main forward force.
The main opposing forces are air resistance (from the wind) and friction (between the tyres and the road)
Since the air resistance + friction = driving force the car moves at a constant speed.
It went under a physical change because it (1) changed color. (2) changed form.
