A thermos bottle contains 150 g of water at 4 oC. Into this bottle is placed 90 g of metal at 100 oC. After equilibrium is established, the temperature of the water and metal is 21 oC. What is the specific heat capacity of the metal? Assume no heat loss to the thermos bottle. cw = 1.00 cal/goC.[3]

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
