The iodide ion, usually consumed as potassium iodide, is a dietary mineral essential to good nutrition. in countries where potassium iodide is added to salt, iodine deficiency or goiter has been almost completely eliminated. the recommended daily allowance (rda) for iodine as 150 micrograms per day. how much potassium iodide (76.45% i) should you consume to meet the rda?

196 micrograms of potassium iodide per day

Explanation:

The question tell us that the requirement is 150 micrograms of iodine a day. Eating 150 micrograms of potassium iodide would not help because iodine would only be 76.45% of that sample. So we need to find a mass m, for which 76.45% is 150 micrograms:

m = 196 micrograms of potassium iodide

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.
