Answer:
168277.2 J
Explanation:
m = Mass of water = 600 g
c = Specific heat of water = 4.186 J/g°C
= Change in temperature of water = 
We know that the amount of heat lost = amount of heat gained
Heat lost by the iron bar is 168277.2 J.
Explanation:
thanks for the points big man
The structure that corresponds to the molecule name - 4-heptanol would be option A.
<h3>Structure of 4-heptanol</h3>
The name, 4-heptanol, indicates that there are 7 carbon atoms in the structure.
