What are the observable properties of salt and rocks, and explain how you used empirical evidence to explain that mixtures of so
777dan777 [17]

Answer:

Appearance. Pure rock salt is colorless. However, when found underground it is generally not completely pure, so may have yellow, red, gray or brown hues. It is either transparent or translucent and when you shine a light on it, its luster is vitreous, meaning it appears shiny and glassy.

1. What is the best means to separate ammonium chloride, sand, and zinc chloride? And a
ozzi

1. A mixture of ammonium chloride, sand, and zinc chloride should be separated by sublimation.

2. A mixture of zinc chloride and silver chloride should be separated through crystallization.

<h3>What is a separation technique?</h3>

A separation technique can be defined as a technique that is typically used to separate or convert two (2) or more mixture and solution of chemical substances into distinct product such as chemical compounds or elements.

<h3>The types of separation technique.</h3>

In Chemistry, there are various types of separation technique used for the separation of mixtures or solutions and these include:

  • Crystallization
  • Fractional distillation
  • Filtration
  • Evaporation
  • Sublimation
  • Decantation
  • Simple distillation
  • Chromatography

In this scenario, the most effective and efficient means to separate a mixture of ammonium chloride, sand, and zinc chloride is by sublimation from solid to gas state.

On the other hand, the best means to separate a mixture of zinc chloride and silver chloride is through crystallization.

Determine the molecular weight of H20.<br> o 18 g<br> O 18.0 g<br> O 18.01 g<br> O 18.016 g
Sonbull [250]

Answer:

The correct answer is D

<u>18.016 g</u>

<u></u>

Explanation:

Molecular Weight : It is the sum of atomic weights of each atoms present in the compound.

The molecular weught is measured in atomic mass.unit( amu) or simply"u"

This is calculated by using :

Molecular weight = number of atom x atomic mass of the atom

For H2O

Number of H atoms = 2

Number of O atom = 1

Molecular weight of H2O = 2(mass of H atom) + 1(mass of O atom)

Molecular weight = 2(1.00784) + 15.999

= 18.01558 u

= 18.016 u
