How much energy is lost when the temperature of 14.6g of paladium decreases from 63°C to 31°C, if the specific heat of aluminum is 0.24 J/g°C?

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?

How many moles of co2 are produced during the complete combustion of 3.6 moles of c2h6
