Conservation of energy
all of it should be transformed since the energy is convserved (neither destroyed nor created)
so answer is B
Substance that undergoes a change in a chemical reaction is
c. A reactant
Answer:
Exothermic reaction.
Explanation:
From the question given, we obtained the following:
The equation for the reaction:
A —> C
From the diagram given in the question above, the reactant, A has a higher energy than the product, C. This simply indicates exothermic reaction as the enthalphy change, ΔH will be negative for the reaction.
Enthalpy change, ΔH is simply the difference between the heat of product, Hp and the heat of reactant, Hr i.e
ΔH = Hp – Hr
Since the heat of the product is small, the enthalphy change, ΔH will be negative indicating that heat has be released to the surroundings. This is termed exothermic reaction.
B. Electrical, chemical, thermal, mechanical.
Turning the ignition switch on sends an electrical signal, which starts the chemical combustion of the fuel. This gets the engine going, which produces heat (thermal).
