Consider the reaction: 2no(g)+o2(g)→2no2(g)estimate î”g∘ for this reaction at each temperature and predict whether or not the reaction will be spontaneous. (assume that î”h∘ and î”s∘ do not change too much within the given temperature range.)a) 298 kb) 723 kc) 842 k

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
