Calculating Enthalpy Changes Flashcards
(3 cards)
1
Q
enthalpy change equation to find heat energy transferred (Q)
A
Q = m x c x ΔH
Q - heat energy transferred (J)
m - mass of liquid being heated (g)
c - specific heat capacity (J/g/degrees C)
ΔH - change in temperature of the liquid (degrees C)
2
Q
what is the specific heat capacity of water?
A
4.2 J/g/degrees C
3
Q
enthalpy change equation to find change in temperature of liquid (ΔH)
A
ΔH = -Q/moles
