Question 7 of 10
Which of the following elements has the largest first ionization energy?
A. Boron (B)
B. Oxygen (0)
C. Carbon (C)
D. Nitrogen (N)

Total moles of gas = 0.1225

Volume of gas produced : 6.7375 L

mass of Nitrogen : 0.588 g

Given

2 ml of Nitroglycerin(ρ=1.592 g/ml)

Required

Total moles of gas

Solution

Nitroglycerin detonated ⇒ decomposition reaction

4C₃H₅N₃O₉(s)⇒ 6N₂(g)+12CO(g)+10H₂O(g)+7O₂(g)

mass of Nitroglycerin :

[tex]\tt mass=2~ml\times 1.592~g/ml=3.184~g[/tex]

moles of Nitroglycerin :

[tex]\tt moles=\dfrac{3.184}{227,0865~g/mol}=0.014[/tex]

Total moles of gas:

[tex]\tt \dfrac{6+12+10+7}{4}\times 0.014=0.1225[/tex]

Volume of gas produced :

[tex]\tt 0.1225\times 55=6.7375~L[/tex]

moles of Nitrogen :

[tex]\tt \dfrac{6}{4}\times 0.014=0.021[/tex]

mass of Nitrogen :

[tex]\tt 0.021\times 28=0.588~g[/tex]

Answer: Barium hydroxide octahydrate

Explanation:

Answer:

C) Electrons will reside closer to chlorine, and the bond will be polar

Explanation:

Electrons tend to be closer or attracted to high electronegativity and sulfur has less electronegativity than chlorine. Therefore, electrons will reside closer to chlorine. To find out if it is polar or nonpolar, according to the electronegativity chart you can find online, you can see that the electronegativity of sulfur is 2.5 while the electronegativity of chlorine is 3.0. Because the difference between these two is a slight change, it would be slightly polar. So, the bond will be polar.

Answer:

Electrons will reside closer to chlorine, and the bond will be polar.
