Explanation:
Chemical energy - electrical energy - light energy
The energy transformation occurring in the battery to the light given off by the computer is from chemical to electrical and to light energy.
A battery is an electrochemical cell that converts chemical energy into chemical energy. In a battery, chemical reactions are used to produce electric currents.
The electric current is an electrical energy.
This energy is used to produce the light given off by the computer.

Answer:
You can divide the mass by the volume to calculate the density of the metal
Explanation:
They all have 2 elections in the outer S orbital, and 4 electrons in the P orbitals.
<span>To convert the number of moles a compound to formula units, the conversion factor is Avogadro's number, 6.022 x10^23 formula units/ mol. In this case, we are given with 7.02 moles of sodium chloride. Hence the answer is 4.23 x 10^24 formula units.</span>
