A is a model of a decomposition reaction
Answer:
=384.48°C
Explanation:
Change in enthalpy is negative because heat energy is lost to the surroundings.
Change in enthalpy= mass ×specific heat capacity× Change in temperature.
ΔH=MC∅
m=14grams
C of iron= 0.45 J/g°C
∅=?
186.0J= 14.0g × 0.45J/g°C×∅
186=6.3∅
∅=29.5°C
Final temperature= 414.0°C - 29.52°C
=384.48°C
Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere.
