A2.241-g sample of nickel reacts with oxygen to form 2.852 g of the metal oxide.
calculate the empirical formula for oxide.

The empirical formula is =

Explanation:

Given that:- Mass of nickel = 2.241 g

Mass of the oxide formed = 2.852 g

Mass of the oxygen reacted = Mass of the oxide formed - Mass of nickel  = 2.852 g - 2.241 g = 0.611 g

Molar mass of nickel  = 58.6934 g/mol

Moles of nickel = = 0.03818 mol

Molar mass of oxygen  = 15.999 g/mol

Moles of nickel = = 0.03818 mol

Taking the simplest ratio for Ni and O as:

0.03818 : 0.03818 = 1 : 1

The empirical formula is =

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
