Answer:
H-Cl is a polar bond.
Explanation:
a polar bond is when 2 different elements share the same electrons except one is negative charge and the other is positive.
Cl is a negative charge while H gives off a positive charge, these are also the only one that have 2 different elements.
Answer:
The molar amount of the gas.
Explanation:
If the pressure, volume, and temperature of a gas are known than molar amount can be determine.
Formula:
PV = nRT
P = pressure
V = volume
R = general gas constant
T = temperature
n = number of moles
Example:
V = 2 L, P = 1 atm , T = 273 K , R = 0.0821 atm. L/mol.K
n = PV/RT
n = 1 atm. 2 L / 0.0821 atm. L/mol.K . 273 K
n = 2 / 22.413 /mol
n = 0.09 mol
Answer:
5.31x10⁻⁶ C
Explanation:
The cube is located 100 m altitude from the ground, so the superior face is at 100m and has E = 70 N/C, and the inferior face is at the ground with E = 130 N/C.
The electric field is perpendicular to the bottom and the top of the cube, so the total flux is the flux at the superior face plus the flux at the inferior face:
Фtotal = Ф100m + Фground
Where Ф = E*A*cos(α). α is the angle between the area vector and the field (180° at the topo and 0° at the bottom):
Фtotal = E100*A*cos(180°) + Eground*A*cos(0°)
Фtotal = 70A*(-1) + 130*A*1
Фtotal = 60A
By Gauss' Law, the flux is:
Фtotal = q/ε, where q is the charge, and ε is the permittivity constant in vacuum = 8.854x10⁻¹² C²/N.m²
A = 100mx100m = 10000 m²
q = 60*10000*8.854x10⁻¹²
q = 5.31x10⁻⁶ C
The new volume of air trapper in the cylinder is determined as 116.56 mL.
<h3>
New volume of air in the cylinder</h3>
The volume of air trapper in the cylinder is determined from Boyle's law;
P₁V₁ = P₂V₂
where;
- P₁ is initial pressure = 1.08 atm
- V₁ is initial volume = 145.7 mL
- P₂ is new pressure = 1.25 x 1.08 atm = 1.35 atm
- V₂ is new volume = ?
V₂ = (P₁V₁)/P₂
V₂ = (1.08 x 145.7)/1.35
V₂ = 116.56 mL
Thus, the new volume of air trapper in the cylinder is determined as 116.56 mL.
