Answers: 1
![[OH^{-}]= 0.01M or 1.0\times 10^{-2}M](/tpl/images/0082/4318/bc443.png)
![[H^{+}]= 1.0\times 10^{-12}M](/tpl/images/0082/4318/aee4e.png)
) is a strong base that dissociates completely.
![[OH^{-}] = 0.005\times 2](/tpl/images/0082/4318/84dc9.png)
= 0.01M or 
![[H^{+}] = \frac{Kw}{[OH^{-}]}](/tpl/images/0082/4318/e9535.png)
![[H^{+}] = \frac{(1\times 10^{-14})}{[OH^{-}]}](/tpl/images/0082/4318/3f081.png)
![[H^{+}] = \frac{(1\times 10^{-14})}{[0.01]}](/tpl/images/0082/4318/e74d5.png)
![[H^{+}] = 1.0\times 10^{-12}M](/tpl/images/0082/4318/a5f50.png)
![pH = -log[H^{+}]](/tpl/images/0082/4318/8d3ec.png)
![pH = -log[1.0\times 10^{-12}]](/tpl/images/0082/4318/9b8a0.png)

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
