One aluminum atom will cost 0.84 × 10⁻²³ cents.
Explanation:
Aluminium costs 85 cents per 453.592 grams.
number of moles = mass / atomic weight
number of moles of aluminium = 453.592 / 27 = 16.8 moles
To calculate the number of aluminum atoms we use the Avogadro's number:
if 1 mole of aluminum contains 6.022 × 10²³ aluminum atoms
then 16.8 moles of aluminum contains X aluminum atoms
X = (16.8 × 6.022 × 10²³) / 1 = 101.17 × 10²³ aluminum atoms
Now, taking in account the aluminium price, we devise the following reasoning:
if 101.17 × 10²³ aluminum atoms costs 85 cents
then 1 aluminum atom costs Y cents
Y = (1 × 85) / (101.17 × 10²³) = 0.84 × 10⁻²³ cents

Answer:
You apply the experiment in real life
Explanation:
if im thinking about how im gonna make a big kaboom explosion, I crash the plane and it makes a big kaboom explosion in the real field
Answer:
C. Less symmetrical than non-polar.
Explanation:
If molecule is symmetrical it can contain polar bond, but sum of all polar moments are equal to zero, and therefore molecule is non-polar.
Hydrogen atom is usually very easy to "polarize", respectively to drag electron pair from it. Because of that lots of molecules that contain hydrogen atoms are polar. Of course greater role in polarity is symmetry of molecules.
Answer:
Percent yield of hydrogen is 87.096%
Explanation:
Theoretical yield = 155g
Experimental yield = 135g
% yield = [experimental yield / theoretical yield] * 100
% yield = (135 / 155) * 100
% yield = 0.87096 * 100
% yield = 87.096 %
The percentage yield of hydrogen is 87.096%
