Answer:
the heat released by the magnesium is 72 kJ
Explanation:
the heat exchanged will be
Q = m*c*(T final - T initial)
where Q= heat released, c= specific heat capacity, T initial= initial temperature of water, T final = final temperature of water
Assuming the specific heat capacity of water as c= 1 cal/g°C=4.186 J/g°C
replacing values
Q = m * c* (T final - T initial) = 1910 g * 4.186 J/g°C*(33.10 °C - 24°C) = 72 kJ
