Moles of Hydrogen present: 100 / 2 = 50 moles
Moles of Nitrogen present: 200 / 28 = 7.14 moles
Hydrogen required by given amount of nitrogen = 7.14 x 3 = 21.42 moles
Hydrogen is excess so we will calculate the Ammonia produced using Nitrogen.
Molar ratio of Nitrogen : Ammonia = 1 : 2
Moles of ammonia = 7.14 x 2 = 14.28 moles
        
                    
             
        
        
        
Light moves in a straight line except at surfaces between different transparent materials, where its path bends.
        
             
        
        
        
Answer:
1.Ecologists often estimate the size and density of. populations using quadrats and the mark-recapture method.
2. The two key components of ecosystem stability are resilience and resistance.
3.The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) affect population
4. When the climate is changing in the colder direction it effects the planet in the opposite way than it does when it is changing in the warmer direction. Ad nauseam the contemporary, it’ll keep getting hotter and at a greater rate so the ecosystem is going to die.
 
        
             
        
        
        
A) all mechanical waves need a medium to travel through.
This is true because mechanical waves move in a wave like manner at the atomic level. This is why an table vibrates when you put a speaker on top of it .
        
                    
             
        
        
        
No,they just separate away from each other
