Carey burns 1.28 grams of chips in a laboratory experiment. He notices the temperature of 50 grams of water in a can above the burning go from 31.5 °C to 63 °C. How many calories did his sample release?

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

Idon’t know what the answer is i wish i could

Heat of fusion= heat/mass  heat of fusion = 12.03kj/36 g= 0.3342 kj/g or 334.2 j/g
