2H₂ + O₂ -------> 2H₂O
mole of H₂ =
=
= 0.7 mol
mole ratio of H₂ : H₂O
= 1 : 1
∴ if mole of H₂O = 0.7 mol
then mole of water = 0.7 mol
Thus:
mass of water = mole x Mr
= 0.7 mol x ((2 x 1) + (1 x 16))
= 12.6 g of water vapour
Answer:
IT PROVIDES MECHANICAL ENERGY
Explanation:
Turbine is a rotatatory device that provides energy from a working fluid and converts it into mechanical energy useful for the generation of electrical energy when combine with an alternator or generator.
It is used in the production of electricity. It begins from the action of a Reactor which provides energy from large radio-active isotopes as they undergo nuclear fission. The energy produced by the Reactor is used to rotate the turbine which provides the mechanical energy needed to transfer energy from a working fluid to the generator. The generator then provides the electrical energy for transmission.
Answer:
Explanation:
The gold piece is cooled by water, meaning that gold is heating the water in the meantime, such that thermal equilibrium is reached. By First Law of Thermodynamics the following relation is found:
Specific heats for gold and water are and . Last expression is simplified by substituting known variables:
