Answer:

A silicon atom has 14 electrons around the nucleus, and of these, there are 4 valence electrons on the outermost orbital. When this is made into a single crystal, it can be used as a material for semiconductor products. When it crystalizes, the nuclei share electrons and they bond with 8 electrons around each nucleus.

Why would you need a locating agent in an experiment to separate amino acids by chromatography
Nadusha1986 [10]

A locating agent is needed in an experiment to separate amino acids by chromatography as it helps to analyze colorless substances on paper.

<h3>What is chromatography?</h3>

Chromatography is an analytical method frequently used to separate a chemical mixture into its components, allowing for in-depth analysis of each component.

There are many different types of chromatography including liquid, gas, ion-exchange, and affinity chromatography, but they all use the same basic principle.

<h3>What is the use of a locating agent in Chromatography?</h3>

In paper chromatography, colorless compounds are examined using a locating agent.

It is a chemical that combines with colorless substances to produce colorful compounds that are easy to see for analysis. Ninhydrin spray is an example of a locating agent of this type.

Thus, a locating agent is used in an experiment to separate amino acids by chromatography as it helps in determining colorless substances on paper.

When chlorine is added to acetylene, 1, 1, 2, 2-tetrachloroethane is formed: 2cl2 (g) + c2h2 (g) → c2h4cl4 (l) how many liters o
Otrada [13]
Answer:
             20 L of Cl₂

Solution:

The reaction is as follow,

                                   H₂C₂  +  2 Cl₂     →      H₂C₂Cl₄

According to equation,

       167.84 g (1 mole) H₂C₂Cl₄ is produced by  =  44.8 L (2 mole) of Cl₂
So,
                 75 g of H₂C₂Cl₄ will be produced by  =  X L of Cl₂

Solving for X,
                      X  =  (44.8 L × 75 g) ÷ 167.84 g

                      X  =  20 L of Cl₂
