Need help with a chem lab!
Im doing a lab about learning to make predictions using the periodic table. I'm comparing four compounds from groups 1 and 2: magnesium carbonate, sodium carbonate, potassium carbonate and calcium carbonate.. mixing them all with water and i guess trying to find the similarities with the properties and reactions. They are all white powders but I'm not sure if my reactions are correct.
i am doing the same with four compounds from group 6 and 7 (or 16 and 17). copper (II) oxide, copper (II) chloride, copper (II) bromide and copper (II) sulfide.
I am also suppose to be noting which are soluable or not, but some in group one/two are and are not and same for group 6/7. so im a little lost. if you can help i would greatly appreciate it and since i may have made this a bit confusiing, basically i really need to know how can we use the periodic table to make predictions??
