Which molecule could form a coordinate covalent bond with a proton (h )?

Answer:

A chlorine (Cl-) molecule could make a coordinated covalent bond with a proton (H +, in this case) forming hydrogen chloride (HCl).

Explanation:

Covalent bonds occur when there is electron sharing between atoms, making all atoms that participate in this type of bond stable, but in the case of coordinated or dative covalent bond, the atom that has available pairs of electrons and is not performing Sharing them with another atom can “donate” these free electrons to any other atom, thereby performing a simple covalent bond and a coordinated or dative covalent bond, where electron (s) transfer from one atom to the other. This type of chemical bond is quite common and often occurs with chlorine, sulfur, phosphorus, among other various chemical elements. As an example we can cite the bond between chlorine and hydrogen to form hydrogen chloride.

For a coordinated covalent bond to occur it is necessary for one of the atoms to share a pair of electrons with another atom, and at the same time assign one or more electrons to another atom, which only participates in the bond receiving the electrons.

Molecule is the smallest particle of a compound or an element with similar properties as the element or the compound. Covalent bond (dative bond) is a bond that is formed due to the sharing of electrons between atoms. Coordinate covalent bond is a type of covalent where electrons shared during bond formation comes from one atom. In this case a molecule of H2O would form a coordinate bond with H+ because the oxygen contains a lone pair of electrons forming H3O+.

What groups of elements do not have a charge and why
Ghella [55]

Answer:

Noble gases because they have a full outer shell of electrons.

Explanation:

Noble gases usually called inert gases are generally non reactive gases. They belong to group 18 elements.They tend to not gain the electron or not give up a electron as they have full valence shells. Because they already have full valence shell and therefore full outer energy level, they are very stable and hardly react with any other elements.

The concentration of a chemical degrades in water according to first-order kinetics. The degradation constant is 0.2 day−1. If t
WITCHER [35]

Answer:

3566.4 days

Explanation:

The reaction follows a first-order

Rate = kC = change in concentration/time

k = 0.2 day^-1

C = 0.14 mg.L^-1

Co = 100 mg.L^-1

0.2×0.14 = 100 - 0.14/t

t = 99.86/0.028 = 3566.4 days

Why can tin (IV) sulfide and antimony (III) sulfide be separated from copper (II) sulfide and bismuth (III) sulfide by the addit
devlian [24]

Answer:

Tin (IV) sulfide and antimony (III) sulfide be separated from copper (II) sulfide and bismuth (III) sulfide by the addition of sodium hydroxide because they become soluble whereas copper (II) sulfide and bismuth (III) sulfide remain insoluble.

Explanation:

Sodium hydroxide is a  basic solution which is used as a precipitating agent for metallic ions in the laboratory.

<em>When a solution containing a mixture of the sulfides of the Group II cations,  antimony (III), copper (II), tin  (IV), and bismuth (III), is made basic by the addition of a base such as sodium hydroxide or ammonium hydroxide, the  sulfide ion concentration will increase. The sulfides of antimony (III) and tin (IV) will then become  soluble because antimony (III) and tin (IV) form stable complexes with sulfide, which are soluble in  water, while the sulfides of copper (II) and bismuth (III) do not.</em> The result is the dissolution of the antimony (III) sulfide  and tin (IV) sulfide, separating them from the copper (II) sulfide and the bismuth (III)  sulfide.

Which type of substance can conduct electricity in the liquid phase but not in the solid phase?
vampirchik [111]
The answer here is ionic compound, because they dissociate in water to form ions that conduct electricity well through the solution.

Molecular compounds and nonmetallic elements tend to be poorer conductors, while metallic elements are good conductors in the solid phase.
