Lewis structure k2s

Potassium sulfide represented by the chemical formula K 2 S is a compound of potassium and sulfur that is moderately soluble in acids [1]. It is deliquescent and may spontaneously ignite in air. It is a reducing agent and an ionic compound [4]. Potassium sulfide can be prepared by first treating potassium hydroxide to excess hydrogen sulfide to form potassium hydrosulfide KHS. Further treatment of KHS with the same amount of potassium hydroxide generates potassium sulfide [9]. Potassium sulfide reacts with cobalt iii bromide to produce cobalt iii sulfide and potassium bromide [10]. Potassium sulfide reacts with dilute hydrochloric acid to produce potassium chloride and hydrogen sulfide [11]. It reacts with concentrated sulfuric acid to give potassium bisulfate, sulfur dioxide, sulfur and water [13]. The compound reacts with silver nitrate to form aqueous potassium nitrate and silver sulfide precipitate [12]. It may cause a fire hazard, so precautions must be taken not to bring it in contact with air. In the form of powder or dust, it is explosive. Ingestion, inhalation and skin contact may result in severe injury and even death. It also harmfully affects the eyes and skin causing eye damage and skin burns.

Draw Lewis structures for ionic compounds. We saw this in the formation of NaCl.

Write the Lewis structure for each ionic compound. Write Lewis structures for the following ionic compounds: a calcium chloride; b barium sulfide; c lithium oxide; d sodium fluoride.

Potassium sulfide K2S consists of two potassium K atoms, each with 1 valence electron, and a sulfur S atom with 6 valence electrons. Sulfur achieves an octet configuration, akin to the noble gas argon, with 8 electrons. The electronegativity difference between K 0. Potassium sulphide k2s is a colourless solid which is yellow in colour when contaminated with any impurities. The molar mass of potassium sulphide is Its odour is like rotten egg as similar to hydrogen sulphide,H 2 S. It is hygroscopic. It can cause serious hazards like skin burns, fire hazards and environmental issues too. Potassium sulphide is prepared by heating potassium sulphate with coke or reacting potassium with sulphur in presence of ammonia.

The following procedure can be used to construct Lewis electron structures for more complex molecules and ions. Beginning with the terminal atoms, add enough electrons to each atom to give each atom an octet two for hydrogen. If any electrons are left over, place them on the central atom.

The transfer process looks as follows:. What is the Lewis dot structure of hcccooh assuming c always forms 4 bonds? These three ions attract each other to give an overall neutral-charged ionic compound, which we write as Na 2 O. Ask a new question Get plagiarism-free solution within 48 hours.

It reacts with concentrated sulfuric acid to give potassium bisulfate, sulfur dioxide, sulfur and water [13].

Lewis structures, also known as Lewis-dot diagrams, show the bonding relationship between atoms of a molecule and the lone pairs of electrons in the molecule. Lewis structures can also be useful in predicting molecular geometry in conjuntion with hybrid orbitals. A compound may have multiple resonance forms that are also all correct Lewis structures.

Submitted by William D. For the Na atom to obtain an octet, it must lose an electron; for the Cl atom to gain an octet, it must gain an electron. What is the formula of a compound that forms between barium and nitrogen? Already have an account? Tags Chemistry Subjects. For a Lewis structure of a single CaH2 molecule, simply place the Ca atom in the center single bonded to two H atoms. We want to correct this solution. With the help of the following data of a company draw up balance sheet. It is of a corrosive nature and poisonous for the environment [8]. Potassium Sulfide Structure.
