The atmosphere becomes colder at bigher elevation as anaeags, the standard atmospheric absolute temperature in kelvin. can be expressed as t288k-(6.510 k/ is the elevation in meters how cold is it outside an airplane cruising at 12,000 m expressed in "

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

um i think it might be a car?
