3:CoSO4

4:Co2(SO4)3

5:CoSO3

6:Co2(SO3)3

Explanation:

1:Co(II) is -2 and S is -2, so the charges cancel

2:Co(III) is -3 and is -2, so you cross the charges but do not reduce

3:Co(II) is -2 and SO4 is -2, so the charges cancel

4:Co(III) is -3 and SO4 is -2 so the charges cross but do not reduce

5:Co(II) is -2 and SO3 is -2 so the charges cancel

6:Co(III) is -3 and SO3 is -2 so the charges once again cross

Answer:

Cobalt (II) sulfide → CoS

Cobalt (III) sulfide → Co₂S₃

Cobalt (II) sulfate → CoSO₄

Cobalt (III) sulfate → Co₂(SO₄)₃

Cobalt (II) sulfite → CoSO₃

Cobalt (III) sulfite → Co₂(SO₃)₃

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.

which characteristic do valence electrons indicate about reactions between atoms?

Answers

Bond number

The characteristic of reactions that depends on valence electrons is the bond type.

In chemistry, a chemical bond could be;

Ionic

Covalent

The type of bond formed depends on the number of valence electrons present. When there are few valence electrons on an atom, it mostly forms ionic bonds.

When there are more electrons on an atoms, it mostly forms covalent bonds and the electrons between the atoms are shared.

explain why boiling is a reversible change​

Answers

Answer:

This is a reversible change. Similarly, if you boil water, it evaporates and becomes water vapor. When you cool this vapor down, it turns back to water. A change which cannot happen backward, that is, it cannot be reversed is called an irreversible change.

Explanation:

When we boil water by heating, then it changes into steam. Now, if we cool the steam, then water is formed again. So, the changing of water into steam has been reversed by cooling. Thus, the boiling of water (or evaporation of water) is a reversible change.

How are covelant and ionic bonds different and what types of elements combine to form each?

Answers

Answer:

Ionic bonds result from the transfer of electrons from one atom to another

Explanation:

In covalent bonds, atoms share electrons, whereas in ionic bonds atoms transfer electrons. The reaction components of covalent bonds are electrically neutral, whereas for ionic bonds they are both charged.Covalent bonds are formed between two non-metals, whereas ionic bonds are formed between a metal and non-metal.  

Answer:

Covalent bonds are defined as sharing of electrons, ionic bonds are the result of transferred electrons;

Covalent bonds form between non-metals (elements) and ionic bonds form between metal and non-metals (ions)

The statement which best describes the hydrogen and oxygen atoms in

water is that the lone pairs of electrons in the oxygen atom causes the

molecule to be bent; the oxygen atom has a partial negative charge, while

the hydrogen atoms have partial positive charges.

Water is a compound which comprises of the elements hydrogen and

oxygen. They  share electrons in the covalent bond present between the

atoms. The sharing of electrons isn't equal which is why it has a bent

structure.

The oxygen atom has a partial negative charge, while the hydrogen atoms

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.

Answers

Imagine A is a Heterogeneous mixture because it a mixture composition that does not stay the same throughout the mixture.
Imagine B is the Homogeneous mixture because it has no changes or irregularities

Imagine A represents a heterogeneous mixture as it is a mixture composition that does not remain the same throughout the mixture whereas Imagine B represents a homogeneous mixture as it does not have any change or irregularity.

What are Homogenous and Heterogenous mixtures?

A homogeneous mixture is defined as having a fairly uniform form and composition, so many homogeneous mixtures are referred to as solutions whereas heterogeneous mixtures are defined as separate substances or phases. The three states or states of matter are gas, liquid and solid.

Some examples of mixtures that include mixtures of sand and water, mixtures of sugar and salt, and mixtures of lime juice and water.

In homogenous solution, particles are distributed uniformly and have uniform composition while in heterogenous solution, particles are distributed non-uniformly and have non-uniform composition

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.

The small flashlight has less inertia and smaller force is required to move it.

According to Newton's first law of motion, an object will continue at rest or in its state of uniform motion unless it is acted upon by an external unbalanced force. This is also called the law of inertia.

The quantity of mass contained in a body is a measure of its inertia. The greater the mass of the body, the greater the inertia and the greater the force required to move the body.
