Answer:
 3300.85 g
Explanation:
Given data:
Mass of ZnCl₂ produced = ?
Mass of H₂ produced = 49.8 g
Solution:
Chemical equation:
Zn + 2HCl     →    ZnCl₂ + H₂
Number of moles of  H₂:
Number of moles = mass/molar mass
Number  of moles = 49.8 g/ 2.056 g/mol
Number  of moles = 24.22 mol
Now we will compare the moles of H₂ with ZnCl₂ form balance chemical equation.
                          H₂              :              ZnCl₂
                           1                :                   1
                         24.22         :              24.22
Mass of ZnCl₂:
Mass = number of moles × molar mass
Mass =  24.22 × 136.286 g/mol
Mass = 3300.85 g
 
        
             
        
        
        
Explanation:
The enzyme 's active site binds to the substrate. Increasing the temperature generally increases the rate of a reaction, but dramatic changes in temperature and pH can denature an enzyme, thereby abolishing its action as a catalyst. ... When an enzyme binds its substrate it forms an enzyme-substrate complex.

Answer : 1.12 grams
Yo find the mass of the sample, you take the increased mass and subtract the original mass. 
6.130 - 5.010 = 1.12
        
             
        
        
        
The answer is: A
C-14 is not stable and this is the reason why it goes through radioactive decay.
