Answer:
d. a brittle solid.
Explanation:
Hello!
In this case, since cesium fluoride is widely known as an ionic compound due to the large electronegativity difference, it is possible to discard a. due to its crystalline structure, b. because conducting solids are metals, c. because ionic compounds are not likely to be gases and e. because even when it is soluble in water, the problem is not referring to an aqueous solution; therefore, the answer is d. a brittle solid.
Best regards!
Answer:
The charge on the metal is +2
Explanation:
Taking a good look at the compound zinc nitride, we will notice that it is made up of zinc and nitrogen.
Zinc has a common common oxidation state of +2 while nitrogen has a common oxidation state of -3. When the two atoms combine, the individual charges on them will be +2 for zinc and -3 for nitrogen according to their common oxidation states.
Hence the answer.
Answer:
See below.
Explanation:
One atom in an ionic compound is displaced by another atom.
For example:
Fe + CuSO4 ---> FeSO4 + Cu.
the copper is displaced by the iron,
Basically this happens because iron is more reactive than copper.
