Answer:
C. Involves a metal and a nonmetal.
Explanation:
Ionic compound involves a metal and a non-metal. Ionic compounds have electrovalent bonds between them.
These compounds are usually made up of metals and non - metals combining to form a unit.
- The metals usually has low electronegativity and transfers it electrons to the non - metal.
- The non-metal has high affinity for the electron.
- The electrostatic attraction between the ions formed results in the ionic bond.
The answer is - ide.
That is how you name the anions in a ionic compound, you replace the ending of the name of the element with ide.
Some examples:
Ionic compound anion name of the anion
NaCl Cl- chloride
KF F- fluoride
NaI I- iodide
CaBr2 Br- bromide
Answer: B. High precision
Explanation:
No disadvantage, it’s important have a lid on a crucible to hand extreme temperatures. The lid may also be used to contain chemicals being heated whilst in a lab.
