Heat
Explanation:
if I hold a beaker during a reaction that is supposedly an exothermic reaction, I will feel that the heat of the beaker. In exothermic reaction, the environment becomes hotter at the end of the change.
- Exothermic reaction is a type of enthalpy change.
- In this kind of reaction, heat is liberated to the surroundings.
- Here, the surrounding becomes hotter at the end of the changes.
- Change in enthalpy is assigned a negative value as the sum of heat contents of products is less than that of the heat content of reactants.

The forces in NH3 includes the vanderwaals force which will always be present and hydrogen bonding due to the electronegativity of N as compared to H. When it is in solution, there will be ionic interactions because there will be some NH4+ ions formed.
Atoms are electrically neutral because they have equal numbers of protons positively charged and electrons negatively charged.if an atom gains or loses one or more electrons it becomes an ion
Answer:
Molten lead bromide, PbBr 2(l), is an electrolyte. During electrolysis: Pb 2+ ions gain electrons at the cathode and become Pb atoms. Br - ions lose electrons at the anode and become Br atoms, which pair up to form Br 2 molecules.
