Help with these questions What is the specific heat of a metal sample if a 35 g sample absorbs 2.3 x 10-3 MJ of heat and its temperature changes from 25°C to 175°C? A 15.5 g piece of metal, heated to 100.0 ºC, is dropped into a calorimeter containing 55.5 g of water at 16.5 ºC. The final temperature of the metal and the water is 18.9 ºC. What is the specific heat capacity of the metal (Cs metal)? As part of your answer, complete the rest of the table with values for water on the left and the metal values on the right. Water Metal q = q = Cs = Cs = m = m = Tfinal = Tfinal = Tinitial = Tinitial = ΔT = ΔT = A piece of nickel is heated to 107.2 °C. It is then submerged into 235.0 g of water at 22.6 °C that is in a coffee cup calorimeter. The final temperature of the mixture is 28.8 °C. What is the mass of the nickel (in nanograms)? Specific heat of nickel is 0.440 J/g°C. The elemental symbol for nickel is _____?(fill in blank)
