Add 2 that’s why and I said if
Answer:
167 kJ
Explanation:
Given parameters
Change in enthalpy = 130 kJ (decrease)
Work done = -137 kJ
Change in energy, \delta = ?
From the first law of thermodynamics:
ΔH = ΔE + PΔV,
Where, ΔH= change in enthalpy
ΔE = change in Internal energy
Substituting values into the above formula —
130 kJ = ΔE + -137 kJ
130 kJ = ΔE - 137 kJ
therefore,
ΔE = (130 + 137 ) kJ
ΔE = 167 kJ
Therefore, the change in energy of the gas mixture during the reaction is 167 kJ.
Since the value of energy change Is positive, therefore this Is endothermic reaction
Answer:
in short weight
Explanation:
weight is mass x gravitational pull on an object
Answer:
Nuclear energy comes from splitting atoms in a reactor to heat water into steam, turn a turbine and generate electricity.
Explanation:
Ninety-five nuclear reactors in 29 states generate nearly 20 percent of the nation's electricity, all without carbon emissions because reactors use uranium, not fossil fuels.
