Use the periodic table to identify each of the following bonds as polar or nonpolar.
Molodets [167]

Answer:

Polar  

Step-by-step explanation:

Electronegativity increases from <em>left to right</em> in the Periodic Table.

Cl is further right than C (both tinted pink) in the portion of the Periodic Table below.

Cl is <em>more electronegative</em> than C, so the Cl has a partial negative charge and the C has a partial positive charge.

The C-Cl bond is polar.

A sample of nitrogen gas occupies 1.83 L at 27 °C and 1.000 atm of pressure. What will
neonofarm [45]

Answer:

1.06L = V₂

Explanation:

Charle's Law states that the volume of a gas is directly proportional to the absolute temperature when pressure remains constant.

The equation is:

V₁T₂ = V₂T₁

<em>Where V is volume and T absolute temperature of 1, initial state and 2, final state of the gas.</em>

V₁ = 1.83L

T₂ = -100°C + 273.15 = 173.15K

V₂ = ?

T₁ = 27°C + 273.15 = 300.15K

V₁T₂ = V₂T₁

1.83L*173.15K = V₂*300.15K

<h3>1.06L = V₂</h3>

Neutral atoms of the same element can differ in their number of
konstantin123 [22]

Answer:

a. neutron

Explanation:

A neutral atom has the same number of protons and electrons because in order for it to be a neutral atom the charges must be the same.

a neutron has no charge therefore it can be different then the number of protons and electrons in a neutral atom as it won't affect the charge.
