Overfishing is an example of human impact on biodiversity.
In simple terms, overfishing means that the sea animals hunted for food ( fishes, crustaceans, mollusks etc.) in a year are hunted in numbers greater than the number of newborn individuals of that species in that year. This means that the populations of these animals do not have the time to regrow their numbers.
This results in a dramatic decline of populations of many marine animals.
Answer: 2 PCl3 + 2 Cl2 > 2 PCl5
Explanation: The factors will be 2 moles of PCl3 reacted to 2 moles of chlorine gas Cl2 and the reaction will produce 2 moles of Phosphorous pentachloride PCl5.
For the reactants 2PCl3 +2 Cl2 there will be 2P, Cl (2x3) +
(2x2) so chlorine will have 10. In the product side 2PCl5. 2 P and Cl will have (5x2)=10.
The chemical reaction will have a balance chemical equation.
