Answer:
11.43g of Aluminum Hydroxide
Explanation:
Since we know that the sulfuric acid is the limiting reactant in this chemical reaction, we know that we are going to be left with excess aluminum hydroxide. So to find the amount of leftover aluminum hydroxide we are going to need to convert the given amount of sulfuric acid to the amount of aluminum hydroxide needed to react with the sulfuric acid.
Once you do that, you need to subtract that number from the amount of aluminum hydroxide given to get the amount of left over aluminum hydroxide.
Hope this helps!
Explanation:
Overpopulation of phytoplankton results in a formation of algal bloom which is harmful because these algal blooms produce highly toxic and harmful compounds that affect the population such as birds, fish, mammals, and also people.
Excessive growth of phytoplankton affect the concentration of carbon dioxide, deplete the oxygen present in water and also results in unavailability of food that affects the marine organisms,
