Answer:
<em>23.9 grams carbon</em>
Explanation:
One mole of carbon is 6.023 x 10^23 atoms of C.
If we calculate moles, we can use the molar mass of carbon (12 g/mole) to determine mass of 12x10^23 atoms of C.
(12x10^23 atoms of C)/(6.023 x 10^23 atoms of C/mole C)
moles C = 1.992 moles C
(1.992 moles C)*(12 g/mole C) = 23.9 grams carbon
Explanation:
because there are 4 Iodines on the left, we'll put. 4 in front of NaI to balance it. This would result in 4 Na on the left, so we'll put a 2 in front of Sodium Sulfate to balance the right side. Now we have 4 Na and I on both side, as well as 2 Sulfate on both sides. Pb is already balanced. The equation is now complete.
Answer:
Comparative- investigations show relationships that do not always indicate cause-and-effect relationships.
Experimental- investigations cannot perfectly reproduce the conditions of the natural world.
Descriptive- investigations often are not repeatable because the results may change over time.
