How many atoms of P are in 3 moles of H3PO4?

2.0*10^24 atoms

Explanation:

To find the number of atoms of P in H3PO4, we need to use the Avogadro's number.

The Avogadro's number is 6.022×10^23.

From there, we can set up a "conversion factor tree" to solve for the number of atoms of P:

3 moles P ×   6.022×10^23 atoms

                      = 2.0*10^24 atoms

                                 1 mol

The moles cancel out and you are left with the number of atoms.

Make sure it's the correct number of sig figs.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

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.
