Answer:
Please find the complete question in the attached file.
Explanation:
It would only be radioactive if the DNA molecule that employed the poly-T rand as templates. Its other molecule of the daughter would not have been radioactive as it did not need dATP for its replication. While each strand of the second molecule includes t, simultaneous reproduction dATP from both daughter molecules is needed so that each of those is radioactive.
Answer: " 13.5 g Al " ;
→ that is: "13.5 grams of aluminum."
<u>____________________________</u>
Explanation:
<u>____________________________</u>
<u>Note</u>: What is missing from the question is the "balanced chemical equation" for the "chemical reaction" that contains:
The reactants: "aluminum (Al) " ; and "chlorine (Cl) " ; and:
The product: "aluminum choloride (AlCl₃) " .
____________________________
The "balanced chemical equation" is:
____________________________
2 Al + 3 Cl₂ → 2 AlCl₃ ;
_____________________________
<u>Note</u>: The molecular weight of "aluminum (Al)" is: " 26.98 g /mol " .
____________________________
So: We call solve using a technique known as: "dimensional analysis" :
____________________________
0.500 mol AlCl₃ *
____________________________
<u>Note</u>: The units of "mol AlCl₃" cancel out to "1' ; and:
The units of "mol Al" cancel out to "1" ; and we are left with:
____________________________
" g Al ["grams of aluminum"] ;
____________________________
<u>Note</u>: We can "cancel out the "2's" ; since "2/2 = 1 " ; and we have:
→ (0.500 * 26.98) g Al ;
= 13.49 g Al ;
→ Round to 3 (Three) significant figures;
→ Since: "0.500" has 3 (Three) significant figures:
____________________________
= 13.5 g Al ; that is: "13.5 grams of aluminum."
