When water at 50 C is added to ice at -12 C, heat is transferred from hot water to ice.
- Heat given out by water = Heat absorbed by ice
Calculating the heat released by hot water:
ΔT
Calculating heat absorbed by 16 g of ice: Ice at 
is converted to ice at 
and then ice at 
to water at 
ΔT + 
+ 
q = 405.12 J +5336.8 J =5741.92 J
- Heat given out by water = Heat absorbed by ice
-(
m = 27.4 g
Therefore, 27.4 g water at 
must be added to 16 g of ice at 
to convert to liquid water at
Fe + 3NaBr → FeBr3 + 3Na
The Na is replaced by the Fe atom.
Explanation:
Molecular formula for Propene = C3H6
The isomer of propene is cyclopropane.
(Draw a triangle to show that it is cyclopropane)
It’s “c. +1” because the Sodium is losing a proton, which has a positive chage
