Coordination complexes can have different types of isomers. compare the types of isomerism in another pair of related coordination complexes. how are these two complexes related to each other?

Answers

Answer 1

Isomers are formed when coordination complexes with two different ligands in the cis and trans positions of a ligand of interest. The octahedral[tex][Co (NH _{3} )_{4} Cl _{2} ] ^{+}[/tex] ion, for example, has two isomers. The two chloride ligands are adjacent to each other in the cis configuration.

Do coordination molecules have various isomers of different types?

The isomers that coordination compounds display include many that are distinct as well as the same isomers that organic compounds display. Compounds known as isomers have distinct structural formulas but the same molecular formula and may not always have the same characteristics.

Which two sorts of isomers are there?

Stereoisomerism and structural isomerism are the two basic types of isomerism (spatial isomerism). Structural isomers are isomers that differ in structure or kind of bond and have the same number of atoms of each kind but differ in how those atoms are connected to one another.

determine the freezing point depression of a solution that contains 30.7 g glycerin (c3h8o3, molar mass

Answers

The freezing point depression of a solution containing 30.7 g of glycerin  is  calculated as -1.65°C

Equating :

It is given that,

Given mass of glycerin is = 30.7 grams (Solute)

Volume of water = 376 mL

[tex]K_{f}[/tex]or molar -freezing-depression point is = 1.86°C/m

Molar mass of glycerin = 92.09 g/mole

Now, to work out the value, the mass of water should be known. Thus, to calculate, the formula used will be:

Mass = Density X Volume

Mass = 1.0 g/mL X 376 mL

Mass = 376 g or 0.376 Kg

Using the formula of melting point depression, the equation becomes:

             Δ[tex]T_{f}[/tex] = i ×[tex]K_{f}[/tex] ×m

T⁰-[tex]T_{s}[/tex]  = [tex]i *K_{f} *\frac{mass of glycerin}{molar mass of glycerin * mass of water in kg}[/tex]

in which,

Δ[tex]T_{f}[/tex] = change in freezing point

Δ[tex]T_{s}[/tex] = freezing point of solution that has to be find

ΔT° = freezing point of water ()

Since, glycerin is a non-electrolyte, the Van't Hoff factor will be 1.

Substituting the values in the above equation:

0⁰C₋T[tex]_{s}[/tex] = 1 ×1.86°C/m ×[tex]\frac{30.7}{92.09g/mol * 0.376kg}[/tex]

[tex]T_{s}[/tex] = -1.65°C

Thus, the freezing point depression of a solution is  -1.65°C

Freezing point depression

Freezing point depression is a colligative property observed in solutions that results from the introduction of solute molecules to a solvent. The freezing points of solutions are all less than that of the pure solvent and is directly proportional to the molality of the solute

Is melting point elevation or depression?

Boiling point elevation is that the raising of a solvent's boiling point due to the addition of a solute. Similarly, melting point depression is the lowering of a solvent's freezing point due to the addition of a solute. In fact, because the boiling point of a solvent increases, its melting point decreases

If any of the substances are ionic compounds, which element is the cation and which is the anion?
Explain your answer.

Answers

AB is an ionic Compound , BC is covalent Compound , AC is an Ionic Compound.

What is Electronegativity ?It is the tendency of an atom in which molecule is usually attract towards the shared pair of electrons which generally is known as electronegativity. As we move across a period i.e from left to right. Here the nuclear charge increases and the atomic size decreases, hence the value of electronegativity increases across a period according to the modern periodic table.Atomic number increases as we move down the group.The nuclear charge also increases but it's effect increase in nuclear charge is overcome with the help of addition of one shell. the value of electronegativity decreases while moving down the group.

Now,

 A = 0.9

 B = 3.0

 C = 3.5

AB is an ionic compound. If the difference of electronegativity between two atoms is more than 1.7 , then they will form ionic compound. Here A is Cation and B is Anion .

Electronegativity difference between A and C = 3.5 - 0.9 = 2.6

     Hence AC is an ionic compound.

A is Cation and B is Anion .

Electronegativity difference between B and C = 3.5 - 3.30 = 0.5

      Hence BC is a covalent Compound.

Thus , from the above conclusion we can say that, AB is an ionic Compound , BC is covalent Compound , AC is an Ionic Compound.

Answers

The molarity of a solution made by dissolving 7.50 g of magnesium nitrate in enough water is 2.04 M

To solve this problem, the formulas and the procedures that we have to use are:

M = n(solute)/v(solution) Ln = m / MWMW= ∑ AWT

Where:

M= molarityn = molesm = massv = volumeMW = molecular weightAWT = atomic weight

Information about the problem:

m = 7.50 gv = 25.0 mlM = ?MW Mg(NO₃)₂ = ?AWT(Mg) = 24 g / molAWT(N) = 14 g / molAWT(O) = 16 g / mol

Converting the volume units from (ml) to (L) we have:

v(solution) =  25.0 ml * (1 L/1000 ml)

v(solution) = 0.025 L

We calculate the moles of the Mg(NO₃)₂ from the MW:

MW = ∑ AWT

MW Mg(NO₃)₂= AWT (Mg) + AWT (N)*2 + AWT (O)*6

MW Mg(NO₃)₂= 24 g/mol + 14 g/mol*(2) + 16 g/mol*(6)

MW Mg(NO₃)₂= 24 g/mol + 28 g/mol + 96 g/mol

MW Mg(NO₃)₂= 148 g/mol

Having the MW we calculate the moles of Mg(NO₃)₂:

n = m / MW

n Mg(NO₃)₂ = 7.50 g / 148 g/mol

n Mg(NO₃)₂ = 0.051 mol

Applying the molarity formula, we get:

M = n(solute)/v(solution) L

M =0.051 mol  / 0.025 L

M = 2.04 M

a. 2 moles of zinc oxide (ZnO)

Answers

The mass of 2 moles of zinc oxide (ZnO) is 162.76g/mol

The International System of Units uses the mole (symbol: mol) as the unit of material quantity. How many elementary entities of a particular substance are present in an object or sample is determined by the quantity of that material. It is specified that the mole contains exactly 6.02214076×[tex]10^{23}[/tex] elementary entities.

As, we know that

moles = mass / molar mass

so, using the formula

2 = mass / 81.38

mass = 162.76g/mol

So,  the mass of 2 moles of zinc oxide (ZnO) is 162.76g/mol

Under what condition does the ideal gas line not apply and gases are considered real? Check all that apply

Answers

Answer:At high pressure and low temperature.

Explanation:

At high pressure voleme of a gas is'nt negligible as compared to the container

And at low temperature, kinetic energy of gas molecules lower, so they come closer to one another and intermolecular forces between them are considerable

when the relative humidity is 100 percent water will condense out of the air evaporation ceases the specific humidity is greater than the saturation specific humidity the saturation specific humidity is greater than the specific humidity

Answers

The air is saturated when the relative humidity reaches 100%.

What is humidity?

The human eye typically cannot see water vapor, which is water in a gaseous condition. The level of humidity reflects the possibility of precipitation, dew, or fog.

The temperature and pressure of the target system have an impact on humidity. In cool air compared to warm air, the same amount of water vapor causes a higher relative humidity. The dew point is a related variable. The higher the temperature, the more water vapor is required to reach saturation.

Magnesium acts similar to sodium when forming an ionic bond in terms of losing or gaining electrons. what is the most likely way in which an atom of magnesium (mg) will satisfy the octet rule when it forms bonds? by losing two electrons by losing four electrons by gaining six electrons by gaining eight electrons

Answers

Answer:

C. by gaining 6 electrons

Explanation:

The most likely way in which an atom of magnesium (Mg) will satisfy the octet rule when it forms bonds is by losing two electrons.

What is octet rule?

The octet rule, a chemical guideline, is based on the idea that main-group elements normally bind so that each atom has eight electrons in its valence shell, giving it the same electrical configuration as a noble gas. Although more broadly applicable to the s-block and p-block of the periodic table, the rule is particularly applicable to carbon, nitrogen, oxygen, and halogens. For example, the duplet rule for hydrogen and helium or the 18-electron rule for transition metals apply to other elements.

An atom of magnesium (mg) will most likely lose two electrons when it makes bonds in order to satisfy the octet rule.

Read the excerpt from John Muir's "Calypso Borealis" and answer the question.[1] After earning a few dollars working on my brother-in law's farm near Portage [Wisconsin], I set off on the first of my long lonely excursions, botanising in glorious freedom around the Great Lakes and wandering through innumerable tamarac and arbor-vitae swamps, and forests of maple, basswood, ash, elm, balsam, fir, pine, spruce, hemlock, rejoicing in their bound wealth and strength and beauty, climbing the trees, revelling in their flowers and fruit like bees in beds of goldenrods, glorying in the fresh cool beauty and charm of the bog and meadow heathworts, grasses, carices, ferns, mosses, liverworts displayed in boundless profusion.[2] The rarest and most beautiful of the flowering plants I discovered on this first grand excursion was Calypso borealis (the Hider of the North). I had been fording streams more and more difficult to cross and wading bogs and swamps that seemed more and more extensive and more difficult to force one's way through. Entering one of these great tamarac and arbor-vitae swamps one morning, holding a general though very crooked course by compass, struggling through tangled drooping branches and over and under broad heaps of fallen trees, I began to fear that I would not be able to reach dry ground before dark, and therefore would have to pass the night in the swamp and began, faint and hungry, to plan a nest of branches on one of the largest trees or windfalls like a monkey's nest, or eagle's, or Indian's in the flooded forests of the Orinoco described by Humboldt.[3] But when the sun was getting low and everything seemed most bewildering and discouraging, I found beautiful Calypso on the mossy bank of a stream, growing not in the ground but on a bed of yellow mosses in which its small white bulb had found a soft nest and from which its one leaf and one flower sprung.
