Answer:

Option C

Explanation:

According to Hund's rule

pairing of electrons occur first in lower energy orbitals then in orbitals having higher energy.

d subshell has 5 orbitals.

so first these 5 get filled.
The. one will be added to first one.

What type of reaction does this illustration represent?

natita [175]

Answer:

The answer to your question is A. Decomposition

Explanation:

In the picture, we can observe that there is only one reactant that after the reaction are formed two products.

We observe that this is a decomposition reaction.

It is not a synthesis reaction, this reaction is the opposite of a decomposition reaction.

In a single-replacement and double-replacement reaction, there is an interchange of cations between the reactants, this does not happen in the picture.

Question 23 (5 points)

iren [92.7K]

Answer:

λ = 6.25 × 10⁻¹⁰ m

x-ray

General Formulas and Concepts:

Speed of Light = Wavelength times Frequency

c = λν

Explanation:

Step 1: Define

C = 3.0 × 10⁸ m/s

ν = 4.80 × 10¹⁷ Hz (s⁻¹)

λ = unknown

Step 2: Solve for wavelength

3.0 × 10⁸ m/s = λ(4.80 × 10¹⁷ Hz)

λ = 6.25 × 10⁻¹⁰ m

Step 3: Check

We are given 3 sig figs. Follow sig fig rules.

6.25 has 3 sig figs. No changes necessary.

Step 4: Identify

6.25 × 10⁻¹⁰ m is in the x-ray spectrum according the the Electromagnetic Spectrum

For the molecule whose condensed structural formula is given below, decide if cis-trans isomers are possible. If they are, enter

ziro4ka [17]

Answer:

cis 2,3-dibromo- 2-butene

trans 2,3-dibromo- 2-butene

Explanation:

The cis-trans or geometric isomerism is due to restricted rotation around a carbon-carbon bond. This restriction may be due to the presence of double bonds or cycles.

The carbon-carbon double bond prevents free rotation of atoms in molecules. These two molecules have the same atoms, but they are different molecules. They are geometric isomers to each other.

The given compound can exist in the form of two isomers, cis and trans. The isomer that has the substituents on the same side is called cis, and the one that has them on opposite sides is trans.
