A hot 105.9 g lump of an unknown substance initially at 154.0 °C is placed in 35.0 mL of water initially at 25.0 °C and the system is allowed to reach thermal equilibrium. The final temperature of the system is 36.2 °C. Using this information and the specific heat values for several metals in the table, identify the unknown substance.
