given that the values of the formation constants are large, what can you deduce about the equilibrium concentration of cu(nh3)4 21 versus the equilibrium concentration of cu21?

Answers

Answer 1

If the formation constants of a complex are large, it means that the complex is more stable than the individual species and therefore, the equilibrium concentration of the complex will be greater than the equilibrium concentration of the individual species.

In the case of Cu(NH3)4^2+ versus Cu^2+ The large value of the formation constant for Cu(NH3)4^2+ suggests that it is more stable than Cu^2+ and the equilibrium concentration of Cu(NH3)4^2+ will be greater than the equilibrium concentration of Cu^2+.It should be noted that large formation constants also indicate that the complex is more difficult to dissociate, and more energy is required to do so.

The average rate is 7.14*10-5 M/s in units

The instantaneous rate of the reaction at t = 800 s can be determined by taking the derivative of the concentration of the reactant or product = 800 s.t with respect to time at that specific point.

However, we don't have an equation describing the relationship between the concentration and time, so we can't calculate the derivative. Instead, we can approximate the instantaneous rate by using the average reaction rate over a small interval of time that includes t=800s.

Using the average rate between 500 and 1200 is a good approximation of the instantaneous rate at t = 800. The average rate is 7.14*10-5 M/s in units.

Answers

Answer:

Explanation:

An equation in point-slope form for the line perpendicular to y=1/4x-7 and passing through (-2,-6) is:

y - (-6) = -4(x - (-2))

This equation can also be written in slope-intercept form (y = mx + b) as:

y = -4x + 4

The slope of the line is -4 because it is perpendicular to the line y=1/4x-7 and the slope of that line is 1/4. The point (-2,-6) is the point where the line passes through, so the y-intercept is 4.

8. distinguish between a strong electrolyte and a weak electrolyte. how can colligative properties be used to distinguish between strong and weak electrolytes?

Answers

There's some characteristic that can distinguish between a strong and weak electrolyte:

1. in strong electrolyte when in aqueous solution, it totally dissociates into ions while  weak electrolyt, in an aqueous solution, it partially dissociates into ions.

2.In strong electrolyte most free ions are present in the solution. while weak electrolyte both free ions and undissociated molecules can be found in its solution.

3. strong electrolyte concentration of ions in the solution is extremely high.

while in weak electrolyte Ion concentration in the solution is low.

4. Strong electrolyte  has high electrical conductivity while weak electrolyte  has some electrical conductivity.

An electrolyte splits into ions when it is dissolved in a solvent like water (or any other conductive species). Because of this, two or more moles of conductive species always result from the dissolution of one mole of electrolyte. As a result, when an electrolyte is dissolved in a solvent, the colliding characteristics of the electrolytes change significantly.

For instance, the following generic equation can be used to describe variations in freezing point and boiling point:

Tb = Kbm, and Tfz = Kfm.

Tfzeeze stands for freezing point depression and Tb for boiling point elevation. The freezing point depression constant is Kf, and the boiling point elevation constant is Kb. The solution's molarity is given by m. The aforementioned equations are adjusted as follows for electrolytic solutions:

iKbm for Tb and iKfm for Tfz

I stands for the Van't Hoff factor, an ion multiplier. The number of moles of ions provided by an electrolyte is equal to this factor. Therefore, the amount of ions released by an electrolyte during its dissolution in a solvent can be used to calculate the Van't Hoff factor. Van't Hoff factor values for NaCl and CaCl2, respectively, are 2 and 3, respectively.

So what is being shown is a phase change diagram. Because we start at an atm of 1.5 (staying steady means that it doesn't drop so we always stay at 1.5 atm) and at a temperature of -150, the original state of matter is a solid. Next, we look at what happens when the temperature goes to 300 degrees, yet still maintaining the 1.5 atm. This means that it now turns into a liquid (based on placement on diagram). This means the matter after the temperature change was a liquid. And going from solid to liquid would be called melting.

The Ka for hypochlorous acid is  0.841 x 10^-8 whose pH of 0.10M HOCl is 4.23 is and its pKa for this acid is 8.075.

Given pH of  hypochlorous acid (HOCl) = 4.23

The concentration of [HOCl] = 0.10M

We know that HOCl is dissociated as follows:

HOCl <==> H+ + ClO-

Ka = [H+] [ClO-]/[HOCl]

Let the concentration of [H+] and [ClO-] be x. Then,

Ka = (x)(x) / 0.10

We know that pH = -log([H+])

[H+] = 10^-4.23 = 0.000058M = 0.58 x 10^-4M

Ka = (0.58x10^-4) * (0.58 x 10^-4) / 0.40 = 0.841 x 10^-8

Then pKa = -log(Ka)

pKa = -log(0.841 x 10^-8) = 8.075

Methane is the second most important anthropogenic greenhouse gas, contributing approximately 20% of the 2.5 W m-2 increase in radiative forcing due to human activities (IPCC (2001)). CH4 also plays a central role in global atmospheric chemistry, affecting tropospheric OH concentrations and acting as a source of stratospheric water vapor. The increase in the total methane burden can be linked qualitatively to increases in human activities that emit methane.

In a sample of 400 lithium atoms, it is found that 30 atoms are lithium-6(6.0g/mol) and 370 atoms are lithium-7(7.0g/mol). calculate the average atomic mass of lithium

Answers

Lithium-6 (6.0g/mol) makes up 30 atoms, while lithium-7 (7.0g/mol) makes up 370 atoms. The average atomic mass of lithium is 0.9750 g/mol.

The average atomic mass of a sample of atoms can be calculated by taking into account the relative abundance of each isotope present in the sample and their individual atomic masses.

In this case, there are 30 atoms of lithium-6 (6.0 g/mol) and 370 atoms of lithium-7 (7.0 g/mol) in the sample of 400 lithium atoms.

To find the average atomic mass, we need to calculate the weighted average of the atomic masses of the two isotopes, using the formula:

average atomic mass = (mass of isotope 1 x % abundance of isotope 1) + (mass of isotope 2 x % abundance of isotope 2) + ...

Where % abundance = (number of atoms of isotope / total number of atoms) * 100

so for the given sample:

average atomic mass = (6.0 g/mol x (30/400)) + (7.0 g/mol x (370/400))

= (0.0375 g/mol) + (0.9375 g/mol)

For which of the following elements could the central atom exhibit sp 3 d 2 hybridization?CSNB

Answers

Since there is not much of an energy difference between the 3p and 3d subshells in S, an electron may move easily between them, making sp³d² hybridization conceivable.

What exactly does hybridization mean?

The process of two key mono DNA and/or RNA molecules joining together to generate a double-stranded molecule is known as hybridization in the context of genomics. The proper base pairing between the four single-stranded molecule is necessary for the bonding.

D begins from the third orbital as the energy disparity between subshells.

As a result, an electron cannot move from the second to the third orbital plane. They are therefore unable to undergo sp³d² hybridization.

A chemist burns 100. 0 g of chromium (Cr) in excess oxygen. There is only one product, and it has a mass of 192. 31 g.

What is the empirical formula of the product?

Answers

The empirical formula of the compound (chromium oxide) formed when 100 grams of chromium is heated in the presence of excess oxygen is CrO₃

How do I determine the empirical formula?

The chemical formula of a compound that gives the proportions (ratios) of the elements present in the compound but not the precise number or arrangement of atoms is known as an empirical formula.

We'll start by figuring out how much oxygen is in the compound. Below is an example of this.

Mass of chromium = 100 grams

Mass of compound  = 192.31 grams

Mass of oxygen =?

Mass of oxygen = (Mass of product) - (Mass of chromium)

Mass of oxygen = 192.31- 100

Mass of oxygen = 92.31 grams

Mass of chromium (Cr) = 100 grams

Mass of oxygen = 32.31 grams

Empirical formula = ?

Divide by their molar mass

Cr = 100/52 = 1.9

O =92.31/16 = 5.7

Divide by the smallest

Cr = 1.9/1.9 = 1

Br = 5.7/1.9 = 3

Answers

Cr(NO) is a non-reactive solution. The most basic solution is NH4Cl. NaI is a weakly acidic solution.

What is compound?

A chemical compound is a substance made of numerous identical molecules joined by chemical bonds and containing atoms from various chemical elements. Therefore, a molecule composed entirely of one element's atoms is not a compound. a material made up of two or more different elements joined chemically. Compounds include things like water (H2O), which is created from the elements hydrogen and oxygen, and table salt (NaCl), which is created from the elements sodium and chloride. A substance made up of two or more constituents is called a compound. Water, carbon dioxide, and table salt are examples of compounds.

Here,

Cr(NO) is neutral solution. NH₄Cl is basic solution. NaI is acidic solution.

he rusting of iron involves the conversion of iron atoms into iron(iii) ions. what change occurs during this reaction?

Answers

Iron atoms are changed into iron(iii) ions during the rusting process. By gaining three electrons, iron atoms are oxidized.

The electrons have vanished.

 In contrast to neutrons and protons which are found inside the atom's nucleus, electrons are discovered outside the nucleus. Negative electrons are drawn to the positive nucleus because their opposing electric charges attract one another.
