Part B structure questions Answer each part, before answering write the part number to be answered. [e. g a (i).]

4.6 g of sodium reacts completely with excess water:

2Na(s) + 2H20 (1)
2NaOH(aq) + H2(g)

Calculate the volume of hydrogen produced. (A, of Na = 23. molar volume = 24 dm)

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.)
