Reacting masses 10. The black solid iron (11) sulfide is formed when iron and sulfur react together. (Ar values: Fe = 56, S = 32)
1 Fe(s) + S(s) → FeS(s)
a How many grams of sulfur will react with 56g of iron?

explanation:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
