Answer:
Your answer is b
Explanation:
the answer is b because if there is no phytoplankton then there will be no fish and if you take out one part of the food chain then the whole chain comes apart. So meaning if there is no phytoplankton, then there is no fish, if there isn't any fish, then the other animals that come to eat at the river will eventually starve to death or move somewhere else to get more food.
Answer:
The reaction is endothermic.
Explanation:
Heat is absorbed in endothermic reactions. An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes (wikipedia)
Standard Enthalpy of Reaction (ΔHrxn) is the amount of heat absorbed (+ΔH value) or released (-ΔH value) that results from a chemical reaction.
Answer:
Boyle´s Law
Explanation:
If we increase the volume of a gas, its pressure will decrease that is why in this question the pressure was decreased to yield the decrease in the number of collisions.
This is Boyle´s law which states that the pressure of a gas is inversely proportional to the volume of its container.
It is expressed mathematically as P₁V₁ = P₂V₂
where the subscripts refer to intial and final conditions.
