Calculate the volume of 4.00 molar NaOH solution required to prepare 100 mL of a 0.500 molar solution of NaOH.
Kazeer [188]

Answer:

The answer to your question is V₁ = 12.5 ml

Explanation:

Data

Volume = V₁?

[NaOH] = C₁ = 4.0 M

Volume 2 = V₂ = 100 ml

[NaOH] = C₂ = 0.5 M

Formula of dilution

                             V₁C₁   =  V₂C₂

Solve for V₁ (original solution)

                                 V₁ = \frac{V2C2}{C1}

Substitution

                                V₁ = \frac{(0.5)(100)}{4}

Simplification

                                V₁ = \frac{50}{4}

Result

                                V₁ = 12.5 ml

If an element is lustrous, brittle, and a semi-conductor, how would you classify it?
just olya [345]

Metalloid

Explanation:

If an element is lustrous, brittle and a semi-conductor, it is best classified as a metalloid.

Metalloids shares attributes of metals and non-metals.

  • They are often described as semi-metals as they do not share the full properties that makes a metal a metal.
  • Metalloids are lustrous but not malleable like metals.
  • They do not conduct electricity but they do so on certain conditions.
  • Examples are silicon, germanium, boron, arsenic e.t.c
  • They are usually found in the middle of the periodic table.
  • They are not readily alloyed with metals.
