Put a small amount of magnesium metal in a crucible and heat gently with a Bunsen burner. Be careful when heating as burning magnesium produces a blinding light. If the magnesium ignites, the lid is quickly placed on
the crucible to extinguish the flame. Here is what the reactants and products looked like. Write the balanced
equation with states of matter and ID types of rxn.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

elements make up everything, and they combine to make compounds.

the answer is c

i think that the answer is c
