The term that is used to label the energy levels of electrons are principle quantum numbers and a valance band refers to the “energy levels in an atom where the electrons that participate in bonding occupy. These energy levels correspond to those of the s and p orbitals of the outermost shell of the atom being considered.” Hope this helps! :)
Answer:
The new volume at -29°C and 432 torr is 6.51 L
Explanation:
Step 1: Data given
Initial volume of CO = 4.63 L
Initial temperature = 296.0 K
Initial pressure = 737 torr = 737/760 = 0.9697 atm
Step 2: Calculate the new volume
(P1*V1)/T1 = (P2*V2)/T2
V2 = (P1V1*T2) / (T1*P2)
⇒ with P1 = the initial pressure = 0.9697 atm
⇒ with V1 = the initial volume = 4.63 L
⇒ with T1 = The initial temperature = 296.0 K
⇒ with T2 = the new temperature = -29.0 + 273 = 244 K
⇒ with P2 = the new pressure = 432/760 = 0.5684 atm
V2 = (P1V1/T1) * (T2/P2)
V2 = 6.51 L
The new volume at -29°C and 432 torr is 6.51 L
Answer:
1 electron
Explanation:
Fluorine is a nonmetal with a high electronegativity and electron affinity so it tends to gain electrons to reach stability. According to the octet rule, fluorine will gain enough electrons so as to complete its valence shell with 8 electrons. Fluorine is in the Group 17 in the Periodic Table, which means it has 7 electrons in its valence shell. Therefore, it will gain 1 electron to complete its octet and form the anion F⁻.
You need to start by subbing in the correct numbers for these values/properties in this formula:
number of moles (mol) = molar concentration (mol/L) x volume (L)

The answer is 1. CO. A gram-molecular mass is defined as mass in grams numerically equal to the molecular weight of a substance or the sum of all the atomic masses in its molecular formula. Since CO2 and CO has both carbon and oxygen, the gram-molecular mass does not change. For a compound with carbon and oxygen, the molecular mass comes respectively from 12 (atomic mass of carbon) + (2 × 16) (atomic mass of oxygen), which is 44 g.
