These are electron dot diagrams.

They use dots arount the symbol of an atom to represent its <em>valence electron</em>s.

You will also see them called <em>Lewis dot symbols</em> or <em>Lewis diagrams</em>.

How much of glucose (C6H1206) is needed to make 1 L of a 1-M solution? Use details to support your answer.
Yakvenalex [24]

Answer:

200 g C₆H₁₂O₆

General Formulas and Concepts:

<u>Chemistry - Solutions</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis
  • Molarity = moles of solute / liters of solution

Explanation:

<u>Step 1: Define</u>

1 M C₆H₁₂O₆

1 L of solution

<u>Step 2: Identify Conversions</u>

Molar Mass of C - 12.01 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar mass of C₆H₁₂O₆ - 6(12.01) + 12(1.01) + 6(16.00) = 180.18 g/mol

<u>Step 3: Find moles of solute</u>

1 M C₆H₁₂O₆ = x mol C₆H₁₂O₆ / 1 L

x = 1 mol C₆H₁₂O₆

<u>Step 4: Convert</u>

<u />1 \ mol \ C_6H_{12}O_6(\frac{180.18 \ g \ C_6H_{12}O_6}{1 \ mol \ C_6H_{12}O_6} ) = 180.18 g C₆H₁₂O₆

<u>Step 5: Check</u>

<em>We are given 1 sig figs. Follow sig fig rules and round.</em>

180.18 g C₆H₁₂O₆ ≈ 200 g C₆H₁₂O₆

Which of the following compounds is not likely to have ionic bonds LiF, NaCI, CH4, MgF2
Rina8888 [55]

Methane CH_{4} does not have ionic bonds. Because of the close value of electronegativity of the carbon and hydrogen atoms the electrons are shared forming covalent bonds.

Define "Dielectric" and list the Dielectric Constant values for vacuum and water
CaHeK987 [17]

Answer:

The term dielectric makes reference to materials that are insulators (the charges in the material does not flow freely and for this reason an insulator material cannot conduce electricity). BUT if we applied this material in an electric field they can be polarized.

Dielectric Constant: It is also defined as a relative permittivity and it is the amount of charge required to produce one unit of electric flux( electric field in a surface)  in a given medium.

it is typically denoted as Epsilon (ε)

and its formula is: ε = ε(ω) /ε(0)

where:

ε(ω) = the frequency-dependent permittivity of the material

ε(0) = the dielectric constant value in vacuum

Dielectric Constant values:

  • For vacuum is always 1
  • for water depending on the temperature can be 87.9 at 0º C, 80.2 at 20º C and 55.5 at 100º C.
