I believe the end result is still 83 moles since there is never an amount of sulfur atoms added to the initial amount, but rather oxygen and water is repeatedly added to it. To find it's weight, first find the molar mass of H2SO4:
H2 + S + O4 = 2.00 + 32.1 + 64.0 = 98.1 g/mol
and mass = (98.1 g/mol)(83 mol) = 8142.3 g
rounded to 8.1 x 10^3 g assuming 100% yield?
        
                    
             
        
        
        
Answer:
B) high temperatures increase the activation energy of a reaction. 
Explanation: 
Ammonia is formed when the nitrogen gas is combined with hydrogen gas in a very high temperature. The high temperature increases the activation energy and nitrogen atom make chemical bonds with hydrogen atom results in the production of ammonia. At room temperature, they cannot react with each other. 
 
        
             
        
        
        
Answer: The algae lives on the crabs and this provides the crabs with a camouflage and gives the algae a place to live so this is beneficiary to both. In other words Spider crabs and Algae are Mutualism to eachothe.
