I need help calculating the specific heat of two unknown metal samples and identifying which metal they are in my general chemistry I calorimetry lab.

Below is the equation needed to use: NOTE- specific heat of water is 4.18

Below are the data from my two trials, we were heating the metal in a test tube and that test tube was in a beaker of water, while preparing the calorimeter with 20ml of room temp. water

initial temperature of metal: 21.00 degrees C

Trial 2 data:

mass of unknown metal: 20.3852g

calorimeter (cups and lid) mass: 10.7164g

20mL H2O+calorimeter mass: 29.4955g

temperature of metal after 10 minutes of heating: 99.2 degrees C

temperature of water after 10 minutes of heating: 99.2 degrees C

temperature of water in calorimeter: 20.2 degrees C

initial temperature of metal: 20.9 degrees C

After we heated the metal and prepared our calorimeter, we added the metal into our calorimeter with 20mL of water and recorded the heat over time, this is shown in the two graphs below. (I think this is where delta T would be obtained)

TRIAL 1 GRAPH:

TRIAL 2 GRAPH:

After you've found the specific heat capacity for both trials, we need to identify which metal trials 1 and 2 are, using the table below. (I used the same metal sample for trial 1 and 2) so only one metal should be identified.

please show work, thank you.
