Answer:
<h2>
2Al +
3CuO ==>
3Cu + Al2O3</h2>
Explanation:
So let's break this chemical equation down into 2 parts - Reactants and Products
Reactants = Al + CuO
Products = Cu + Al2O3
So the Chemical Reaction will be
Al + CuO ==> Cu + Al2O3
So the balanced equation will be,
2Al + 3CuO ==> 3Cu + Al2O3

Answer:
electron shells
Explanation:
Eletrons are on the outeermost part of the atom called electron shells.
Based on observation of polar and non-polar molecules, polar molecules would attract each other more strongly.
<h3>What are polar and non-polar molecules?</h3>
Polar molecules are those molecules that can ionize or dissociate into their respective positive and negative ions when in an aqueous solution.
Nonpolar molecules, on the other hand, are not ionic i.e. not dissociating into ions when dissolved in water.
Polar molecules like water (H2O) contains an uneven distribution of cations (+) and anions (-), hence, would be more attracted to one another than nonpolar molecules that have an even distribution of ions.

The atomic weight reported in the periodic table of elements for Carbon is the average weight of all the known isotopes of Carbon occurring naturally. There are 3: Carbon-12, Carbon-13 and Carbon-14. The numbers represent the mass numbers, or the sum of neutrons and protons in the nucleus. Each of the individual masses are multiplied with their individual percentage abundances. Then, when you add them up, it will yield the average atomic weight equal to 12.011 amu or grams/mole C.
