Answer: Aluminium
Explanation:
The metals are solid substances, they have shiny luster, they conduct electricity and have high melting point. The aluminium is a kind of metal that have a solid surface, it has a shiny luster, the surface of metal appears to be polished. It conducts electricity and can be used in electrical cords, connections, and devices. It has a high melting point.
0.161 mols.
Balance the equation first
2Fe + O2 •••••> 2FeO
Find the molar masses of the compound
2(56) + 2(16) •••••> 2(56+16)
112g + 32g •••••> 144g
Fe reacting with O2
112g of Fe reacting with 32g of O2
18g of Fe reacting with x
x= 32×18/112
x= 5.143g
Amount= mass/ molar mass
Amount= 5.143g/32g
Amount= 0.161mls
