A 20.0-gram piece of metal at 88OC is cooled by a sample of water to 25OC. The amount of energy (energy given off by the metal is = energy absorbed by the water) is 320 Joules. Determine the specific heat of the unknown metal.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

the complete reaction for the formation of aluminum oxide is as follows;

4al + 3 > 2

so if the molar mass of the is 32.0 g/mol and

so, to form 3.80 mol of

(3.80 mol ) x (3 mol ) x (32.0 g )

dividing by 2 because two moles of will be formed;

∴ 364.8/2   = 182.4g
