Hi sorry to bother I know that you guys can only answer 3 questions per the ask questions so I was wondering if you could solve the following 3 for me please thank you

Chem 143 Specific Heat Capacity Lab Report Temperature of hot water bath(trial 3): 100 7 (С5) Tw = -9m Final Temperature(trial 3): 23.5 (C6) Analysis 1.) Look at your temperature data tables for the three trials. For each find the highest temperature that your calorimeter reached. This is the final temperature of both the calorimeter and the metal shot. Write this temperature in the data section on the (A6, B6, C6) line. 2.) Calculate the change in temperature of the water in your calorimeter, ATwater. ATWater= Trfinal-Tinitial= (A6, B6, C6)-(A4, B4, C4) Alo=27.2 Blo = 24.4 cle = 23.5 ATWater (trial 1)= (A7) %3D A4= 24.4 34= 21.4 C4= 20.2 ATWater (trial 2)= (B7) %3D ATWater (trial 3)= (C7) 3.) Calculate the amount of energy that went into warming up the water in your calorimeter. We will call this qwater. Use the following equation. 9Water= mWater°C Water"A Twater Here mwater is what you wrote for (A3, B3, C3), cWater=4.184 g.°C J and ATWater=(A7, B7, C7). qWater (trial 1) = x 4.184…

In the calorimetry experiment, what will happen if the temperature was recorded prior to the stabilization of the temperature reading? Select one: a. Magnitude of calculated ΔH > actual value b. Magnitude of calculated ΔH = actual value c. There is no need to wait for the stabilization of the temperature reading because it will not have much effect on the computed value. d. Magnitude of calculated ΔH < actual value

Please help me show all the work as I will be using this to study, double and triple check your answers as previous tutors got it wrong
