The efficiency : 95%
<h3>Further explanation</h3>Efficiency : the ratio between output and input work
In general, the value of the output of a machine is less than the value of the input because of the frictional force in the machine.
The greater the efficiency of the engine, the better the machine
Can be formulated :
w output = 190 J
W input = 200 J
The efficiency :
Answer:
Explanation:
Hello,
In this case, for the given chemical reaction:
The standard entropy change is computed by subtracting the products standard enthalpy and the reactants standard enthalpy considering each species stoichiometric coefficients:
Best regards.
The deuteriuoted water that is consists of an isotope of hydrogen in place of hydrogen from the normal water. The approximate mass of deuteriuoted water and normal water can be calculated as {(2×2)+16} = 20. However the exact mass of
is 20.027 g/mole, whereas the mass of water can also be calculated as- {(1×2)+16}=18, however the exact mass of (
) molecule is 18.015 g/mole. Thus the difference between the mass of the molecules are (20.027 - 18.015) = 2.01 2g/mole.
