<span>Electronegative atoms or atoms where electrons spend more of their time orbiting the atom's nucleus giving the atom a negative charge. When electronegative atoms such as oxygen bond to hydrogen they pull the hydrogen's electron to themselves becoming even more electronegative. This causes the hydrogen side to become positive. The molecule formed is a polar molecule. Molecules with positive ends and negative ends are called polar.</span>
The empirical formula of metal iodide : CoI₃(Cobalt(III) Iodide)
<h3>Further explanation</h3>
13.02 g sample of Cobalt , then mol Co(MW=58.933 g/mol) :
Mass of metal iodide formed : 97.12 g, so mass of Iodine :
Then mol iodine (MW=126.9045 g/mol) :
mol ratio of Cobalt and Iodine in the compound :
Answer:Difference between Ceres and Pluto
Nestled in the asteroid belt between Mars and Jupiter, Ceres is a tiny loner, while Pluto — in the Kuiper Belt at the edge of the solar system — is nearly three times as big and hosts a handful of moons. A mixture of rock and water ice dominates Ceres' landscape, while methane and nitrogen ices cover Pluto
