<span>ionic compounds usually involve a metal and a non metal, and non ionic (or covalent) bonds are usually between 2 non metals
a) Fe3P2 Iron is a metal, Phosphorus is a non metal so it is likely to be non ionic
p.s metals are on the left of the periodic table and non metals on the right</span>
Answer:
C Hydrogen bonding is the main force that attracts water molecules to
one another.
Explanation:
Hydrogen bonding affects water molecules because, it is the main force which holds and attracts water molecules to one another.
- Hydrogen bonding is an intermolecular force.
- Intermolecular forces holds molecules together. Examples are van der waals forces, hydrogen bonding.
- In a hydrogen bonding, hydrogen of one molecule electrostatically combines with a more electronegative specie usually nitrogen, flourine and oxygen on another atom.
- This attraction results in hydrogen bonding between two or more molecules.
- The unique and anomalous behavior of water is as a result of these hydrogen bonds between its molecules.
Answer:
The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth's terra firma. The terrestrial planets are the four innermost planets in the solar system.
