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.

If the pressure, volume, and temperature of a gas are known, which can most lik
morpeh [17]

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

6. The Earth’s electric field is directed vertically downward; at the ground level its strength is E = 130 N/C, and at an altitu
Alexxx [7]

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

Air trapped in a cylinder fitted with a piston occupies 145.7 mL at 1.08 atm pressure. What is the new volume when the piston is
Anon25 [30]

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.

Which of these is a benefit of including comments in your code
morpeh [17]

A benefit of including comments in your code is that it helps other programmers understand your code.

<h3>What is a Code?</h3>

These are numbers and letters which are used to identify a particular thing at a point in  time.

Comments can be put in a code so as to enable others know and understand real intentions about it etc.
