Compound= many parts together therefore bike is the answer
Answer: The correct option is, (B) 12.3 KJ
Solution :
First we have to calculate the moles of water.
Now we have to calculate the amount of heat released.
Formula used :
where,
q = heat released
n = number of moles = 2.04 mole
= molar enthalpy of fusion of a substance = -6.01 KJ/mole
Now put all the give values in the above formula, we get the amount of heat released.
The negative sign indicate heat released.
Therefore, the amount of heat released is, 12.3 KJ

The question is accompanied of a table showing the atomic masses and abundances of the five isotopes and asks to calculate the atomic mass of the element with five significant figures. You just have to add the products of the atomic mass of each isotope times its abundance and divide by 100. This is the calculation:<span>
(179.946706*0.12 + 181.948206*26.5 + 182.9502245*14.31 + 183.9509326*30.64 + 185.954362*28.43 ) / 100 = 183.84 (which is rounded to five significant figures)</span>
Its either b or c, but i think its b
