Which of these refers to the strength of an acid?
measure of the quantity of acid dissolved in water

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.)

Rank the four gases (air, exhaled air, gas produced from from decomposition of h2o2, gas from decomposition of nahco3) in order of increasing concentration of co2

A155.0 9 piece of copper at 182 °c is dropped into 2500 g of water at 23.9 °c. (the specific heat of copper is 0.385 1/9°c.) calculate the final temperature of the mixture. (assume no heat loss to the surroundings.)
