What is the main exception in the atomic radius? Explain.
yarga [219]

Answer:

The atomic radius of atoms generally decreases from left to right across a period. There are some small exceptions, such as the oxygen radius being slightly greater than the nitrogen radius. Within a period, protons are added to the nucleus as electrons are being added to the same principal energy level.

hope this helps!

Given the DNA template strand 3\' AACAGACAG 5\', write the amino acid sequence in the N-terminal to C-terminal direction. Use th
Stolb23 [73]

Answer: The amino acid sequence is Leu-Ser-Val

Explanation: To produce amino acids, the DNA has to "transform" itself into a RNA by a process called Transcription. In this process, part of the DNA is transcribed into a similar RNA. The RNA produced undergoes another process, called Translation. From it, the sequence is decoded to a specific polypetide, as shown in this case. In the Translation, each 3 bases corresnpond to 1 amino acid. Because of it, the sequence above has 3 amino acids.

The N-terminal and C-terminal relates to the part where the sequence start to be read and the end of the process. Normally, the sequence starts at the 5', which correspond to the N-terminal and finishes at the 3', which matches the C-terminal. So in this example, the DNA template read 5\'GACAGACAA 3\'.

erik [133]

Answer:

\% Fe^{+2}=70%

Explanation:

Hello,

In this case, we could considering this as a redox titration:

Fe^{+2}+(Cr_2O_7)^{-2}\rightarrow Fe^{+3}+Cr^{+3}

Thus, the balance turns out (by adding both hydrogen ions and water):

Fe^{+2}\rightarrow Fe^{+3}+1e^-\\(Cr_2^{+6}O_7)^{-2}+14H^++6e^-\rightarrow 2Cr^{+3}+7H_2O\\\\6Fe^{+2}+(Cr_2^{+6}O_7)^{-2}+14H^++6e^-\rightarrow Cr^{+3}+7H_2O+6Fe^{+3}+6e^-

Thus, by stoichiometry, the grams of Fe+2 ions result:

m_{Fe^{+2}}=0.04021\frac{molK_2Cr_2O_7}{L}*0.02872L*\frac{6molFe^{+2}}{1molK_2Cr_2O_7}*\frac{56gFe^{+2}}{1molFe^{+2}}=0.388gFe^{+2}

Finally, the mass percent is:

\% Fe^{+2}=\frac{0.388g}{0.5562g}*100\%\\  \% Fe^{+2}=70%

Best regards.
