The following information is given for magnesium at 1 atm: Tb 1090.00°C Tm = 649.00°C Specific heat solid = 1.017 Specific heat liquid = 1.339 A 33.70 g sample of solid magnesium is initially at 635.00°C. If the sample is heated at constant pressure (P = 1 atm), temperature of the sample to 712.00°C. J g. °C J g. °C AHvap (1090.00° C) = 5424 J/g AH fus (649.00°C) = 368.3 J/g kJ of heat are needed to raise the

A 20.0 g sample of brass, which has a specific heat capacity of 0.375 J.g¹°C¹, is dropped into an insulated container containing 250.0 g of water at 75.0 °C and a constant pressure of 1 atm. The initial temperature of the brass is 9.0 °C. Assuming no heat is absorbed from or by the container, or the surroundings, calculate the equilibrium temperature of the water. Be sure your answer has 3 significant digits. °C x10 1 X Ś

What is AG (in kJ) for 2 SO2(g) + O2(g) – 2 S03(g) at 700 K, under standard conditions of 1 bar partial pressure for all gases, given that K = 3.0×10“ at 700 K? O -60. +36 0.0 +60. -36

A 124 gram ice cube at -33°C is placed into a 2.50 kg iron container (assume no energy is transfered as heat to or from the surroundings). The temperature of the iron container drops by 55°C. Calculate the final temperature in °C of the water in the container. The density of water is 1.00g/mL and the heat capacity of ice to be 37.7 J mol-1K-1 and the heat capacity of water is 75.3 J mol-1K-1. The molar enthalpy of fusion of water is 6.01 kJ/mol and the heat capacity of iron is 0.45 J/(gK).

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
