Citrus2011 [14]
Acceleration (change of movement) of an object is dependent on the net force acting on it and its mass.

The relationship between acceleration (a), force (f) and mass (m) is given by the Second Lay of Newton: f = m * a.

Note that the force, f, is the net force acting on the objetct.

I hope this help you.

What type of compound is fe3n2
Shkiper50 [21]

Fe3N2, also known as Iron (II) nitride, is an ionic compound.


Ionic compounds are compounds that consists of metals and non-metals bonded with ionic bonds. The metal ion gives up electron(s) to the non-metals.


Since iron is a metal and nitrogen is an non-metal, the bond they would form would be an ionic bond. Iron gives up 2 electrons to form iron(II) ion, while nitrogen gains 3 electrons to form nitride ion. Since one iron cannot let a nitrogen gain 3 electrons, so in the compound, there would be 3 iron (ii) ions that has given up 6 electrons in total while 2 nitride ions have gained 6 electrons in total.
