Answer:
I would think C because you dont want to sell it (A), you dont want to conduct it or launch it agai, (B or D), so you would redesign it to make it better.
 
        
                    
             
        
        
        
I think the correct answer from the choices listed above is the first option. She concluded that the reaction is an exothermic one because t<span>he reaction released heat. Exothermic is when heat goes out of the system. The opposite is referred to as an endothermic reaction.</span>
        
                    
             
        
        
        
Answer:
Mass of sample is 99.9 g, density of ample is 11.35  and temperature of sample is
 and temperature of sample is 
Explanation:
Mass is an additive property. Therefore mass of combined sample is summation of masses of two pellets.
Mass of combined sample = (37.2+62.7) g = 99.9 g
Density is an intensive property. Therefore density of combined sample of lead will be same as with density of Pb.
Density of combined sample = 11.35 
Temperature is an intensive property. Therefore temperature of combined sample of lead will be same as with individual pellets.
temperature of combined sample =
