27.0g of an unknown metal at 100 degrees Celcius was dropped into a beaker containing 313g of water initially at 22.3 degrees Celcius. The final temperature of the mixture was 25.1 degrees. What is the specific heat capacity of the unknown metal?

The element that has the greatest electronegativity is

What natural processes produce large quantities of co2

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.)
