General Chemistry 2 Assignment

Question1:

We have a bomb calorimeter with a heat capacity of 555 JK. In this bomb calorimeter, we place 10000 ml of water. We hum 2376 g of a sold in this bomb calorimeter. The tempera of the bb calorimeter and e water increases by 2.05 C. The molar mass of the solid is 592.3 g/mol. How much beat (in kJ) will be released if we were to burs 0.136 mol of this same solid in the bomb calorimeter Keep in mind the amout of heat minised. The specific heat capacity or water is 4.384 1Kg Approximate the density of water as being exactly 100 g/ml

Question 2:

The standard enthalpies of formation, at 25.00 °C. of methane (CHg, water (HO), and carbon diende (CO) arr, respectively, 346ml, 2858 mol, and -9955 mol Call the amount of heat released (in kJ) during the combustion of 1733 Lof methane under a constant perssure of 1000 atm at 25.00 °C (NB. combustion is the reaction with molecular oxygen to produce water and carbon dioxide)

Question 3:

We place a metal rod weighing 500g with a specific beat capacity of 0.358 1Kg in 212 ml of water. The specific heat capacity of water is 4 164 J/Kg and we make the approximation that in density is exactly 1000 gin. The water has an initial temperature of 200 °C and the metal rod has an initial temperature of 87.5 °C. What is the final temperature (in C) of the water and metal rod?
