I’m not an expert and I haven’t taken chemistry in like a year but i believe you use stoichiometry to do this equation. It should look something like this.

The rate of change in the amount of silver supplied is equal to the ratio of the difference in the amount supplied to the number of years elapsed from 2005 to 2008. That is,
               rate of change = (25 - 200) / (2008 - 2005) = -173/3
The answer is letter A. 
        
                    
             
        
        
        
Answer:
q1 = mCpΔT
     = 18.016g × 1.84J/g.K × (418.15-373.15)
      = 1491.72 J
q2 = n×ΔH vap
      =  1mol ×44.0kJ/mol
      = 44KJ
∴ qtotal = q1+ q2
              = 1.498kJ + 44.0kJ
              = 45.498KJ
Explanation: The heat flow can be separated into steps.all that is being observed at a constant pressure,the heat flow is equal to the enthalpy.
 
        
             
        
        
        
Answer:
True water is wet because when something is wet in this case it's water it has water on it at a molecular level. Water molecules are bonded on top of each other so it's wet.
