Top: The grasshopper population would begin to have a dramatic increase because of the lack of being eaten if the frogs disappeared and the snakes would decrease in population because of less food availability.
Bottom: All of the organisms in the food chain are equally as important because a drastic change would occur if one disruption was made.
Answer:
a. endothermic reaction
Explanation:
In an endothermic reaction, heat is absorbed from the environment. This leaves the surrounding at a colder temperature compared to the system.
ΔH, the change in enthalpy is assigned a positive sign because the heat energy level of the final state is higher than that of the initial state.
Some examples are mostly dissolution substances in water.
Incomplete combustion occurs when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide. ... Carbon monoxide is a poisonous gas, which is one reason why complete combustion is preferred to incomplete combustion.
In this case a double displacement reaction will take place.
