PLEASE HELP! DUE IN 5 MINS SUPER EASY CHEMISTRY!! Which of the following compounds contain the largest number of atoms?

C

Explanation:

Since they all are 2 mols worth, all you have to do is count the number of atoms in each molecule

H2SO4 contains 2 hydrogen 1 sulfur 4 oxygen                = 7 atoms

H2S      contains 2 hydrogen and 1 sulfur                          = 3 atoms

H3PO4 contains 3 hydrogens 1 phosphorus  4 oxygens = 8 atoms

HNO3   contains 1 hydrogen 1 nitrogen and 3 oxygens   = 5 atoms

You have the right answer.

i dont know

explanation:

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.
