Why do some transition metals have multiple oxidation states?

Transition metals have multiple oxidation states because of their (a. completely filled b. partially filled c. empty) (s, p, d, or f) sublevel.

Answers

Answer 1

Answer:

because of energy difference between (n1)d and ns orbitals (sub levels) and involvement of both orbital in bond formation

Explaination:

the reason is that there is a difference in energy of orbitals of an atom of transition metal, so there (n1)d orbitals and there ns orbitals both make a bond and for this purpose they lose an electron that is why both sublevels shows different oxidation state.  

Hope this helped you

Answer 2

Transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.

What are transition metals?

Transition metals are defined as essentially, a configuration attended by reactants during complex formation, as well as the reaction coordinates.

It can also be defined as a very short-lived atomic configuration at a reaction-energy diagram's local energy maximum.

Transition metals are best defined as an element with a partially filled d sub-shell on its atom or that can give rise to cations with an incomplete d sub-shell.

Transition state is defined as a chemical reaction is defined as a certain configuration along the reaction coordinate.

Oxidation state is defined as the total number of electrons that have been deleted or added to an element.

It can also be defined as an atom's charge if all of its links to other atoms were entirely ionic.

Thus, transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.

AgF (aq) + KNO3 (aq) →

Answers

Answer:

AgF (aq) + KNO₃ (aq) → AgNO₃(aq) + KF(aq)

Explanation:

AgF (aq) + KNO₃ (aq) →

The products from the equation above can be obtained as follow:

1. AgF and KNO₃ will dissociate in solution as shown below:

AgF (aq) —> Ag⁺(aq) + F¯(aq)

KNO₃ (aq) → K⁺(aq) + NO₃¯(aq)

2. A double displacement reaction will occur between AgF and KNO₃ as illustrated below:

AgF (aq) + KNO₃ (aq) →

Ag⁺(aq) + F¯(aq) + K⁺(aq) + NO₃¯(aq) → Ag⁺NO₃¯(aq) + K⁺F¯(aq)

AgF (aq) + KNO₃ (aq) → AgNO₃(aq) + KF(aq)

A careful observation of the above equation shows that the equation is balanced.

Explanation:

It is important to know the properties and chemical formulas of ionic and molecular compounds because, knowledge of the properties of a compound aids you in deciding how to use the compound, how to store it and how dangerous it can be. Knowledge of its formula is the first step towards identifying its properties since most chemicals occur in groups having similar chemical/physical properties.

Knowledge of the chemical properties and formula of bleach and drain cleaner will help you to decide which product is a better cleaning agent based on its chemical composition. This will help you as the user to make  better decision.

SCIENCE A meteorologist uses a weather map to explain an upcoming change in weather. The map shows a blue line with triangles approaching a red line with semicircles. Based on the map, which weather prediction is most valid? (1 point) A a significant drop in temperature will occur across the area. B There is no chance of precipitation in the forecast. C Warm temperatures will replace cold temperatures. D Humidity levels will rise.

Answers

Answer:

The correct option is D) Humidity levels will rise

Explanation:

A rise in humidity means that it is most likely there is going to be a rain.

When blue semi-circle lines with triangles approach red semi-circle lines it is a situation where cold front is approaching a warm front.

The resultant effect is that the warm and cold air both come to a standstill. This will most likely trigger cloud and fog and may even lead to rain.

Answers

Answer:

C. Bohr’s model showed that electron orbits had distinct radii

Explanation:

In Rutherford's atomic model, the electrons moved on arbitrary orbits, which was only due to the condition that the Coulomb force acts as a radial force. In Bohr's atomic model, only very specific orbits were allowed, which were determined by Bor's quantum condition.

Explanation:

you need 16.66ml (+-0.01) of 53.4 (+-0.4)wt% of NaOH with a density of 1.52 (+-0.01)g/mL to prepare 2.00L of 0.169M of NaOH. What is the uncertainty in the molarity of NaOH. FM of NaOH=39.9971 g/mol. Neglect the uncertainty in the final volume and FM.

Answers

Answer:

The absolute uncertainty is approximately 1.69 × 10⁻³

Explanation:

The volume needed for NaOH needed to make the solution = 16.66 ml

The wt% of the added NaOH = 53.4 wt%

The volume of the NaOH to be prepared = 2.00 L

The concentration of the NaOH to be prepared = 0.169 M

The molar mass of NaOH = 39.997 g/mol

Therefore, 100 g of sample contains 53.4 g of NaOH

The mass of the sample = 16.66 × 1.52 = 25.3232 g

The mass of NaOH in the sample = 0.534 × 25.3232 = 13.5225888 g ≈ 13.52 g

Therefore;

The number of moles of NaOH = 13.52/39.9971 = 0.3381 moles

Therefore, we have 0.3381 moles in 2.00L solution, which gives;

The number of moles per liter = 0.3881/2 = 0.169045 moles/liter

The molarity ≈ 0.169 M

The absolute uncertainty, u(c) is given as follows;

[tex]u(c) = \sqrt{ \left (\dfrac{0.01}{16.66} \right )^2 + \left ( \dfrac{0.4}{53.4} \right )^2 + \left ( \dfrac{0.01}{1.52} \right )^2 } \times 0.169 \approx 1.69 \times 10^{-3}[/tex]

The absolute uncertainty, u(c) ≈ 1.69 × 10⁻³.
