Answer:

You can easily predict the group of any element by it's valence shell configuration. If the valence e confgn is ns1 then it belongs to 1 group if it is ns2 then it is 2 group element. For p block elements it is 10+ no of es of ns& np. Eg. Cl 3s2 3p5. So group no is 17. For d block elements group no is equal to ns+ (n-1) d es. For e.g. Cr 4s1 3d5 . Group no is 6. For f block elements group no is always 3.

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.
