1. Which combinations of substances resulted in a chemical change?

I'm honestly so confused by this entire lab, any help would be appreciated. If you're doing k12 chem, reaction of metals lab.

2. For each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table.
3. Were there any metallic compounds that did not react with either the acid or the base? Write the type of metal, based on your examination of the periodic table.
4. Make a general statement about the reactivity of the metals in this experiment.

. For each metal that participated in a chemical change, write the type of metal it is, based on yourexamination of the periodic table.Answer: Ammonium Vanadate appears to be mostly a post transition metal. Manganese sulfate also hasmore post transition atoms than transition atoms. Iron nitrate is a transition metal. The cobalt nitrate is atransition metal. Copper nitrate is a transition metal. Zinc nitrate is also a transition metal.(5 points)3. Were there any metallic compounds that did not react with either the acid or the base?

Make a general statement about the reactivity of the metals in this experiment.Answer: The transition metals in this experiment were all reactive when mixed with one of the twosubstances. The alkali and alkaline earth metals, however, did not react at all.
