Answer:
=0.1293 J
Explanation:
The heat increase is the change in energy for the water ΔH.
ΔH=MC∅ where M is mass, C is the specific heat capacity for water and ∅ is the change in temperature.
M=0.7892g
C(for water) =4.2 J/g°C
∅=0.039 °C
ΔH=0.7892g×4.2 J/g°C×0.039°C
=0.1293 J
The amount of heat energy added to cause the 0.039°C temperature increase is 0.1293 Joules.
It will always be equal to the mass of the reactants in a reaction.
Answer:
23.8 torr
Explanation:
Vapor pressure of a liquid is simply the pressure of the vapor that arises when the liquid evaporates in a closed container above the liquid sample.
From the question given above, the vapor pressure is 23.8 torr at 25°C. Since the temperature is constant, the vapor will remain the same when equilibrium is reached in the new container as vapor pressure depends on the temperature of the liquid.
