Answer:
Solid gallium is a blue-gray metal with orthorhombic crystalline structure; very pure gallium has a stunning silvery color. Gallium is solid at normal room temperatures, but as well as mercury, cesium, and rubidium it becomes liquid when heated slightly
Explanation:
gallium is like water it freezes to turn solid!

Answer:
The ΔS° for this reaction is -626.22 J/K.
Explanation:
The equation used to calculate ΔS° is of a reaction is:
![\Delta S^o_{rxn}=\sum [n\times \Delta S^o_f(product)]-\sum [n\times \Delta S^o_f(reactant)]](https://tex.z-dn.net/?f=%5CDelta%20S%5Eo_%7Brxn%7D%3D%5Csum%20%5Bn%5Ctimes%20%5CDelta%20S%5Eo_f%28product%29%5D-%5Csum%20%5Bn%5Ctimes%20%5CDelta%20S%5Eo_f%28reactant%29%5D)
The equation for the enthalpy change of the above reaction is:
We are given:
Putting values in above equation, we get:
The ΔS° for this reaction is -626.22 J/K.
The reaction is a synthesis reaction.
<h3>What are synthesis reactions?</h3>
Synthesis reactions are one of the numerous reactions in chemistry. These kinds of reactions involve the combination of two atoms of different elements resulting in the formation of new compounds.
Synthesis reactions are sometimes referred to as combination reactions, simply because they have to do with the combination of two or more atoms of different elements into a single compound.
The different elements that combine are referred to as the reactants while the result of the combination is known as the product.
For example: A + B --> AB
In the illustrated reaction, N2 combined with H2 to form NH3. N2 and H2 gases are the reactants while NH3 is the only product formed from the two reactants.
This is a good example of a synthesis/combination reaction.
