A beaker contains 1.5 x 10^23 zinc atoms. How many moles of zinc are present in the beaker?

1/4

Explanation:

1.5 * 10^23 atoms zinc * 1 mole zinc/ 6 *10^23 atoms = .25 moles zinc

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.
