<u>Answer:</u> The correct answer to this problem is 2.
<u>Explanation:</u>
We are given a mathematical problem, which is:
1 + 1 = ?
To solve this, we use the mathematical operator known as addition. In this, we add two numbers and the resulting value is the answer to the problem.
By adding 1 and 1, we get:
Thus, the correct answer to this problem is 2.
The heat required to melt the compound is<u> 2.56kJ.</u>
Why?
To calculate the heat required to melt 25.7 g of solid methanol, we need to calculate its molar mass, know its chemical formula, its molar heat of fusion, and calculate how many moles represent 25.7g of the same compound.
Then, we need to use the following formula to calculate the heat:
Where,
N is the moles of the compound
u, is the molar heat of fusion of the compound (J/mol)
We know that the molar mass of methanol is :
So, we can calculate the number of moles that represents 25.7g of the same compound:
Also, the molar heat of fusion of methanol is:
Now, substituting into the first equation and calculating, we have:
Hence, we have that the heat required to melt the compound is 2.56kJ.
Have a nice day!
