Hydrogen, hydrogen ion (H+) is associated with acids
When the heat lost by water = heat gained by ethanol
∴( M* C * ΔT )w = (M*C*ΔT ) eth
when Mw mass of water = 40 g
C specific heat of water = 4.18
ΔT = (70- Tf)
and M(eth) mass (ethanol) = 40 g
C specific heat of ethanol = 2.44
ΔT = (Tf - 10 )
by substitution:
40* 4.18 * (70 - Tf) = 40 * 2.44 * (Tf-10)
∴Tf = 47.9 °C
