Using the chemical equation provided, calculate the number of moles of hydrogen sulfide produced when 0.28 mol of aluminum sulfide and 1.30 mol of water react. nearest hundreths.
Al2S3 + 6H2O à 2Al(OH)3 + 3H2S

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

put the answers   and i could answer.

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.
