When a 1.0 g sample of a candy bar is combusted in a bomb calorimeter whose total heat capacity (including the water) is 5.0 kJ/oC, the temperature of the water increases by 6.0 oC. If the candy bar has a mass of 28 g, calculate the total number of Calories that it contains. (1 Calorie

Why do cells appear different in distilled water than they do in 10% salt water?

In 2002, the rare earth elements mine in mountain pass, california was closed because

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.)
