Answer:
Both contain a hydroxyl group on the second carbon.
Neither contain a hydroxyl group on an end chain carbon.
Explanation:
2,2-butanediol Formula: C4H10O2
2,3,4-pentanetriol Formula: C5H12O3
Both contain a hydroxyl group on the second carbon.
Neither contain a hydroxyl group on an end chain carbon.
Answer:
Ba>Sn>Pb>As>S
Explanation:
Hello,
In this case, we can write the atomic radius for the given elements:
In such a way, the required order is:
Ba>Sn>Pb>As>S
This is also in agreement as a periodic trend which states that the higher the period, the higher the radius.
Regards.
Correct Answer: <span>(3) Electronegativity and first ionization energy both increase.
Reason:
Electronegativity and ionization energy are dependent on effective nuclear charge and size of atom.
As we move along the periodic table from left to right, atomic size decreases and effective nuclear charge increases. The increase in effective nuclear charge and decrease in atomic radii favor ionization energy and electronegativity.
Hence, in 3rd period (from Na to Cl) electonegativity and 1st ionization energy increases. </span>
Hey There!
number of moles = 0.250 moles NaCl
Volume = 1.25 L
Therefore:
M = n / V
M = 0.250 / 1.25
M = 0.2 mol/L
hope this helps!
Yes all living things are organisms and they have cells.
