Is Dioxin chemical ionic or covalent and acidic or basic? Explain
aliya0001 [1]

Answer:

<h3>Learning Objective </h3><h3>Identify element pairs which are likely to form ionic or covalent bonds </h3><h3>Key Points </h3><h3>Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points and electrical conductivity compared to covalent compounds.</h3><h3>Dioxins are a group of highly toxic chemical compounds that are harmful to health. They can cause problems with reproduction, development, and the immune system. They can also disrupt hormones and lead to cancer. Known as persistent environmental pollutants (POPs), dioxins can remain in the environment for many years. </h3><h3>Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds. </h3><h3>Terms </h3><h3>electronegativity: The tendency of an atom or molecule to attract electrons and form bonds. </h3><h3>octet rule: Atoms lose, gain, or share electrons in order to have a full valence level of eight electrons. Hydrogen and helium are exceptions because they can hold a maximum of two valence electrons. </h3><h3>valence electrons: Electrons in the outermost principal energy (valence) level of an atom that can participate in the formation of chemical bonds with other atoms. </h3><h3>Two Classes of Compounds </h3><h3>Compounds are defined as substances containing two or more different chemical elements. They have distinct chemical structures characterized by a fixed ratio of atoms held together by chemical bonds. Here, we discuss two classes of compounds based on the bond type that holds the atoms together: ionic and covalent. </h3><h3 /><h3>Covalent Compounds </h3><h3>Covalent bonds are characterized by the sharing of electrons between two or more atoms. These bonds mostly occur between nonmetals or between two of the same (or similar) elements.Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled. </h3><h3 /><h3>Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), and iodine monobromide (IBr). </h3><h3 /><h3>Ionic Compounds </h3><h3>Ionic bonding occurs when there is a large difference in electronegativity between two atoms. This large difference leads to the loss of an electron from the less electronegative atom and the gain of that electron by the more electronegative atom, resulting in two ions. These oppositely charged ions feel an attraction to each other, and this electrostatic attraction constitutes an ionic bond. </h3><h3 /><h3>Ionic bonding occurs between a nonmetal, which acts as an electron acceptor, and a metal, which acts as an electron donor. Metals have few valence electrons, whereas nonmetals have closer to eight valence electrons; to easily satisfy the octet rule, the nonmetal will accept an electron donated by the metal. More than one electron can be donated and received in an ionic bond. </h3><h3 /><h3>Some examples of compounds with ionic bonding include NaCl, KI, MgCl2.</h3>

While playing soccer, Carla slides across one of the lines on the field. When she stands up, what base does she dust off? calciu
babunello [35]

The soccer field has been placed with the outlines of the slaked lime. The chemical dust off from the falling has been calcium hydroxide.

<h3>What is slaked lime?</h3>

The boundary wall to the soccer or the other field has been marked with slaked lime powder. The chemical has the ability to react with bacteria and act as a disinfectant.

The slaked lime chemically is a white powder of calcium hydroxide. Thus, after falling on the soccer field, the chemical dusted off by Carla is calcium hydroxide. Thus, option A is correct.

Calculate the ΔHrxn for the following
Vesnalui [34]

Answer:

2 NO (g) → N2 (g) + O2 (g)

2 NOCl (g) → 2 NO (g) + Cl2 (g)

____________________________

2NOCl (g) ⟶ N2 (g) + O2 (g) + Cl2 (g)

ΔH = [90.3 kJ x 2 x -1] +  [-38.6 kJ x -1 x 2] = -103.4 kJ

The ΔH for the reaction is -103.4 kJ
