If 2.0 L of 0.500 M solutions of NH3 is completely used up in a reaction with O2, how many grams of oxygen is needed? Molar mass of O2 is 31.998 g/mol.

that's what i got you can count the number of atoms

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.
