Aqueous sulfurous acid decomposes into sulfur dioxide gas and liquid water. Write a chemical equation for this reaction.

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.)

40dm3 of gas at 760 torr are heated from 5°c to 50°c what is the new volume
