Calculate DELTA G for C(graphite) ----> C(diamond).

25 1. T The specific heat of water is 4.18 J-g-¹ K-¹. How much heat is required to raise the temperature of 500 g of water from 20 °C to the boiling point (100 °C)? What is the molar heat capacity of water? Specific heat of 11₂0= 4₁185.5-1-14-1 motor mass of waver: 18,001g/mol mas of water = 5003 a. 5 D HRAMCAT Hear = 500g (thit 3). 2014 Initial Temp: 20%= 2931 molar hear capacity & spresse head capacting of w Anal Temp: 100% = 3731 Hear =? Molar heat coperty? Hent = 1672003 Hear = 167.23 = 4.182 * 75,23/10.19 2. In studying the energy generated by a person, you may view the person roughly as a constant pressure calorimeter using sugar (i.e., sucrose, C12H22O11) to generate power. The reaction of table sugar in a calorimeter is given by C. Q b. Calculate the enthalpy of combustion per mole of sugar utilization. Does the result of your calculation make sense? C12H22O11(s)+120₂(g) →12CO₂(g)+11H₂O+heat. →give the magnitudo (no sign is recessure) What is the heat released by consuming one…
