The wall of an industrial furnace is constructed from 0.15-m-thick, fireclay brick having a thermal conductivity of lz w/m. k. measurements made during steady state operation reveal temperatures of 1400 and 1150 k at the inner and outer sur- faces, respectively. what is the rate of teat loss through a wall that is 0.5 m by 1.2 m on a side?

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

sry but any answer choices
