A 50.00 g sample of an unknown metal is heated to 45.00°c. it is then placed in a coffee-cup calorimeter filled with water. the calorimeter and the water have a combined mass of 250.0 g and an overall specific heat of 1.035 cal/g•°c. the initial temperature of the calorimeter is 10.00°c. the system reaches a final temperature of 11.08°c when the metal is added. which of the following equations is the correct one to use to calculate the specific heat of the metal?
O c subscript p metal equals startfraction m metal delta t metal over m calories c subscript p calorites delta t calories endfraction.
O c subscript p metal equals startfraction negative m calories c subscript p calories delta t calories over m metal delta t metal endfraction.
