Answer: Option (B) is the correct answer.

Explanation:

Heat of fusion is defined as the heat energy required to convert a solid substance in liquid state.

So, when we heat a solid substance then the heat absorbed by it helps in breaking of intermolecular forces of attraction. As a result, solid substance will start to melt and during this change the temperature remains constant until the substance completely melts which is known as latent heat of fusion.

Hence, we can conclude that the temperature of a substance remains constant as its heat of fusion is added to melt the substance.

Balanced nuclear equation, what two things must be conserved
In-s [12.5K]
If you only want to balance nuclear reactions, then you should know that number of nucleons are conserved before and after nuclear reaction. Also, charge is conserved as well.
Other things which are conserved in a nuclear reaction are:
Conservation of:
1. Parity
2. Spin
3. angular momentum(vector sum of intrinsic spin and orbital angular momentum)
4. linear momentum
5. Isotopic spin
6. Energy

Which pair of atoms has the highest electronegativity difference?
zavuch27 [327]
The best way to accurately determine the pair with the highest electronegativity difference is by using their corresponding electronegativity values. For the each of the choices, the difference is:

A. H-S = 2.5 - 2.1 = 0.4
B. H-Cl = 3 - 2.1 = 0.9
C. N-H = 3 - 2.1 = 0.9
D. O-H = 3.5 - 2.1 = 1.4
E. C-H = 2.5 - 2.1 = 0.4

As show, D. has the highest difference. Without looking at their values, you can also determine the pair with the highest difference by taking note of the trend of electronegativity on the periodic table. Electronegativity increases as you go right a group and up a period. This makes oxygen the most electronegative element among the other elements paired with hydrogen.
