Melting Point: 155 °C (311 °F; 428 K)
Explanation:
The melting point of ammonium phosphate is 155 °C (311 °F; 428 K). The melting point is the temperature at which a compound will melt.
It is a physical property of most substances usually determined in the laboratory.
- Most solids, especially ionic salts have very high melting points.
- Ammonium phosphate is no exception.
- It is one of the key ingredients used in making plant fertilizers to ensure they grow properly.
- It is a white grain substance.
- It is an unstable compound made up of ammonium and phosphate salts.

Answer:
The Relative Formula Mass of Fe(NO₃)₂ is 179.8524 grams
Explanation:
The Relative Formula Mass is the mass of one mole of a compound expressed in grams, obtained by adding together the Relative Atomic Masses, RAM, of the elements which makes the compound
The Relative Formula Mass of a compound is the same as its Relative Molecular Mass
The relative formula mass of Fe(NO₃)₂ is given as follows;
The relative atomic mass of Fe = 55.845 amu
The relative atomic mass of nitrogen, N = 14.0067 amu
The relative atomic mass of oxygen, O = 15.999 amu
Therefore, we have;
The formula mass of Fe(NO₃)₂ = (55.845 + 2×(14.0067 + 3×15.999)) amu = 179.8524 amu
The Relative Formula Mass of Fe(NO₃)₂ = 179.8524 grams.
The electronic configuration of the elements which share the group, must have the last electron in same block..
In chemistry, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
