Answer:
-41. 47
Explanation:
m = q / Cp x T
m = Mass
q = Energy (or joules)
Cp = Heat Capacity
T = Change in Temperature
Water's heat capacity is always 4.18.
This is the formula you'll need for change in temperature:
Final - Initial
So, 33 - 78 = -45
m = 7800 / 4.18 x -45
= -41.47
Heat require to boil 15.6 g iron from 122 C0to 355 C0 whereas,
Where, m is mass of iron
s is specific heat of iron
d T is change in temperature in celcius
If
1 cal = 4.2 J
Then,
Thus 0.389 k cal of enrgy is required by a 15.6 g Fe to reach to 355 C^0

Carbon products are obtained by heating coal (to give coke), natural gas (to give blacks), or carbonaceous material of vegetable or animal origin, such as wood or bone (to give charcoal), at elevated temperatures in the presence of insufficient oxygen to allow combustion.
