8. Butane, which is the fuel used in cigarette lighters, combusts according to the following thermochemical equation: 1002 2 C4H10(g) + 13 O2(g) → 8 CO2(g) + 10 H₂O(g) AH = -5316.6 kJX LR If 10.0 g of butane burns completely in oxygen and the heat is used to warm up 25.0 L of water at 22.0 °C, what will be the final temperature of the water (assuming that no heat is lost to the surroundings and that d = 1.00 g/mL for water))? 2 5 UVILS Dr. Lara Baxley *** WH 13/0 but

When 0.8451 g of naphthalene (C10H8) combusts in a bomb calorimeter, the temperature rises by 1.538°C. What is AUrxn for the reaction in kJ/mol naphthalene? The heat capacity of the bomb calorimeter is 22.15 kJ/°C. O Respond with the correct number of significant figures in scientific notation (Use E notation and only 1 digit before decimale.g. 2.5E5 for 2.5 x 10) Type your numeric answer and submit

A 23.56 g sample of a substance is initially at 23.7 °C. After absorbing 2083 J of heat, the temperature of the substance is 144.2 °C. What is the specific heat (c) of the substance? c = g-C * TOOLS x10

A 113.9 g piece of copper (specific heat 0.38 J/g･°C) is heated and then placed into 400.0 g of water initially at 20.7°C. The water increases in temperature to 22.2°C. What is the initial temperature of the copper? (The specific heat of water is 4.18 J/g･°C).

A sample of 0.750 g of peanut butter was burned in a coffee cup calorimeter filled with 300.0 g of water. The heat released caused the temperature of the water to increase 14.6°C. Note: heat capacity, C, of the water is 1.00 cal/g･°C. Calculate the caloric content of the peanut butter in nutritional calories per gram. Remember a nutritional calorie (C) is 1 kcal.

A 137.9 g piece of copper (specific heat 0.38 J/g･°C) is heated and then placed into 400.0 g of water initially at 20.7°C. The water increases in temperature to 22.2°C. What is the initial temperature (in °C) of the copper? (The specific heat of water is 4.18 J/g･°C).
