The diatomic molecule that is formed when two atoms share six electrons is N2.
The atomic number of nitrogen is 7 and its electronic configuration is 2,5. This implies that, nitrogen has 5 electrons in its outermost shell. To attain the octet structure, it needs 3 electrons more. To form a diatomic molecule, two nitrogen atoms come together and each donate three electrons, which are equally shared between the two, thus, each ends up having 8 electrons in its outermost shell.
Answer:
Option C (1.2 L) is the correct option.
Explanation:
The given values are:
Pressure,
![P_1=1.9 \ atm](https://tex.z-dn.net/?f=P_1%3D1.9%20%5C%20atm)
![P_2=3.8 \ atm](https://tex.z-dn.net/?f=P_2%3D3.8%20%5C%20atm)
Volume,
![V_1=2.3 \ L](https://tex.z-dn.net/?f=V_1%3D2.3%20%5C%20L)
![V_2=?](https://tex.z-dn.net/?f=V_2%3D%3F)
As we know,
The gas equation is:
⇒ ![PV=nRT](https://tex.z-dn.net/?f=PV%3DnRT)
At constant temperature,
⇒ ![P_1 V_1=P_2 V_2](https://tex.z-dn.net/?f=P_1%20V_1%3DP_2%20V_2)
or,
⇒ ![V_2=\frac{P_1 V_1}{P_2}](https://tex.z-dn.net/?f=V_2%3D%5Cfrac%7BP_1%20V_1%7D%7BP_2%7D)
By substituting the values, we get
⇒ ![=\frac{1.9\times 2.3}{3.8}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1.9%5Ctimes%202.3%7D%7B3.8%7D)
⇒ ![=\frac{4.37}{3.8}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B4.37%7D%7B3.8%7D)
⇒ ![=1.15 \ L](https://tex.z-dn.net/?f=%3D1.15%20%5C%20L)
or,
⇒ ![=1.2 \ L](https://tex.z-dn.net/?f=%3D1.2%20%5C%20L)
The IUPAC naming of compounds follow a set of rules. First, find the longest carbon chain and number them. As shown in the picture, the longest chain has 9 carbons. In the 3rd and 5th carbon atoms, there is a double bond for each. So, the parent chain is named as 3,5 - nonadiene, 'di' because there are two double bonds. Moreover, at the 5th carbon, there is a branching chain of two carbons (ethyl). Hence, its IUPAC name is: <span>(3e,5z)-5-ethyl-3,5-nonadiene.</span>
Answer:
2.24 g
Explanation:
First we use the<em> PV=nRT</em> formula to <u>calculate the number of moles of the gas</u>:
- 0.957 atm * 1.30 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 298 K
Then we can use the<em> given molar mass</em> to <u>calculate the mass</u>:
- Molar Mass = Mass / number of moles
- 44.01 g/mol = Mass / 0.0509 mol
