Determine the [Ag+] present in solution at equilibrium when the complexing agent ammonia is added to a 0.025 M solution of AgNO3 to result in a [NH3]eq = 0.15 M.


Solubility constant (Ksp) for Ag(NH3)2 2+ is 1.7 * 10^7.

Answers

The concentration of [Ag+] present in the solution is 6.53 × 10⁻⁸ M

From the given information, the equation for the reaction between silver ion and ammonia can be represented as:

Ag⁺ + 2NH₃ ↔ [Ag(NH₃)₂]⁺

Given that the solubility constant (Ksp) for the product formed = 1.7 × 10⁷.

The solubility constant for this reaction can be expressed as:

[tex]\mathbf{Ksp = \dfrac{[Ag(NH_3)_2]^+}{[Ag^+][NH_3]^2} }[/tex]

where;

concentration of ammonia = 0.025 Mconcentration of silver nitrate = 0.15 M

[tex]\mathbf{1.7 \times 10^7 = \dfrac{0.025}{(x)(0.15)^2}}[/tex]

[tex]\mathbf{1.7 \times 10^7 = \dfrac{1.1111}{x}}[/tex]

[tex]\mathbf{x = 6.54 \times 10^{-8} \ M}[/tex]

Therefore, we can conclude that the concentration of  [Ag+] = x = 6.54 × 10⁻⁸ M.

What is oxidation state?​

Answers

Answer:

a number assigned to an element in chemical combination which represents the number of electrons lost (or gained, if the number is negative), by an atom of that element in the compound

Explanation:

sodium, magnesium, iron is zero.

The definition of oxidation state is as follows: Oxidation state is a number given to the atom of an element when participating in a chemical reaction.

OXIDATION STATE:The atoms of elements are not always neutral i.e. carry no charge. They sometimes carry either positive or negative charges to become ions.

Ions can either be cations (positively charged) or anions (negatively charged). The amount of charges are represented by numbers placed as a superscript in front of the element involved.

These superscript charge assigned to a corresponding element during a chemical reaction is called oxidation state. The oxidation state of an element portrays the number of electrons gained or lost during the reaction.

Therefore, oxidation state can be defined as a number given to the atom of an element when participating in a chemical reaction.

Answers

When energy is added to a system during phase change, the particles move faster.

When a substance is heated, the internal energy within a system associated with the motion of particles and that can be added to a substance is called thermal energy.

During a phase change, when more energy is added to the system, the particles within the system will have greater motion and the temperature will increase.

The attractions that hold molecules together are electrostatic forces. The correct statement about the attractions that hold particles is that attractions between particles break when  attractions due to Electrostatic forces when particles move fast enough these forces can no longer keep particles together.

Rubber band  is not a perfect comprehension for Bonds in a substance when considering phases change because for a phase change from liquid to gas the bonds do not break completely the particles can still slide past each other.

methane is called an organic compound why​

Answers

Answer:

Explanation:

1) Organic compounds always contain only p-block elements (Groups III-VII), at least one of which must be carbon. 2) Organic compounds almost always contain one or more C-H bonds. ... Thus, all bonds are typically covalent in organic compounds. Methane (CH4) is the prototypical organic molecule.

Methane contains carbon, forming covalent bonds, and is found in living organisms, making it an organic compound.

Methane (CH₄) is considered an organic compound due to its molecular structure and occurrence in living organisms. Organic compounds are primarily composed of carbon atoms covalently bonded to hydrogen and often other elements like oxygen, nitrogen, sulfur, and more.

Methane consists of one carbon atom bonded to four hydrogen atoms through covalent bonds. Carbon's unique ability to form stable covalent bonds with other elements, including itself, leads to the vast diversity of organic molecules found in living organisms.

Methane is a crucial component of natural gas and is produced by various biological and geological processes. It is present in the digestive systems of animals, formed during decomposition, and plays a role in carbon and energy cycles.

Its prevalence in living systems and its molecular structure classify methane as an organic compound, reflecting the foundational principles of organic chemistry.

Use your periodic table, notes on transition metals, and polyatomic ion table to correctly answer the following:
What is the ionic compound formed from calcium and sulfide ions?
Select one:
O a.
Cas
O b. Ca s
O c. CaSO4
O d. CazS2

Answers

Answer:

The high melting point is also consistent with its description as an ionic solid. In the crystal, each S2− ion is surrounded by an octahedron of six Ca2+ ions, and complementarity, each Ca2+ ion surrounded by six S2− ions.

Explanation:

You can use the periodic table to predict whether an atom will form an anion or a cation, and you can often predict the charge of the resulting ion. Atoms of many main-group metals lose enough electrons to leave them with the same number of electrons as an atom of the preceding noble gas. To illustrate, an atom of an alkali metal (group 1) loses one electron and forms a cation with a 1+ charge; an alkaline earth metal (group 2) loses two electrons and forms a cation with a 2+ charge, and so on. For example, a neutral calcium atom, with 20 protons and 20 electrons, readily loses two electrons. This results in a cation with 20 protons, 18 electrons, and a 2+ charge. It has the same number of electrons as atoms of the preceding noble gas, argon, and is symbolized Ca2+. The name of a metal ion is the same as the name of the metal atom from which it forms, so Ca2+ is called a calcium ion.

When atoms of nonmetal elements form ions, they generally gain enough electrons to give them the same number of electrons as an atom of the next noble gas in the periodic table. Atoms of group 17 gain one electron and form anions with a 1− charge; atoms of group 16 gain two electrons and form ions with a 2− charge, and so on. For example, the neutral bromine atom, with 35 protons and 35 electrons, can gain one electron to provide it with 36 electrons. This results in an anion with 35 protons, 36 electrons, and a 1− charge. It has the same number of electrons as atoms of the next noble gas, krypton, and is symbolized Br−. (A discussion of the theory supporting the favored status of noble gas electron numbers reflected in these predictive rules for ion formation is provided in a later chapter of this text.)

The graph below shows the solute concentration inside a paramecium over time. What is happening at the time indicated by the pointer?



Water is moving rapidly into the paramecium by osmosis.
Water is moving rapidly out of the paramecium as the contractile vacuole contracts.
The paramecium is having a meal.
Solutes from the surrounding water are diffusing through the cell membrane, causing the solute concentration inside the paramecium to rise.

Answers

The pointer indicated the point at which water is moving rapidly out of the paramecium as the contractile vacuole contracts.

The pointer specifically indicates where the water solute concentration dropped. In order for the solute concentration of the water to drop, more water would have to be added.

This means that water from the paramecium moves into the surrounding water as the contractile vacuole contracts. Consequently, the solute concentration of the surrounding solution decreases.

When water moves from the solution into the paramecium, the solute concentration increases and this forms a continuous cycle in the graph.
