Al(s) + O2(g) > Al2O3(s) a) Balance the above equation.

b) How much aluminum oxide can be produced from 10.0 grams of oxygen?

c) How much aluminum oxide can be produced from 10.0 grams of aluminum?

d) What is the limiting reagent? How do you know this?

e) If the reactions actually produced 8.50 grams of Al2O3, what is the percent yield?

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )

the correct answer would be b) volume versus temperature, because they are also directly proportional.
