10.5 milliliters of 3.5 M zinc hydroxide react completely with 15.0 milliliters of 4.9 M nitric acid.

<h3>What is molarity?</h3>

It is a unit of concentration equivalent to moles of solute per liter of solution.

  • Step 1: Write the balanced equation.

Zn(OH)₂ + 2 HNO₃ ⇒ Zn(NO₃)₂ + 2 H₂O

  • Step 2: Calculate the reacting moles of Zn(OH)₂.

10.5 mL of 3.5 M Zn(OH)₂ react.

0.0105 L × 3.5 mol/L = 0.037 mol

  • Step 3: Calculate the reacting moles of HNO₃.

The molar ratio of Zn(OH)₂ to HNO₃ is 1:2.

0.037 mol Zn(OH)₂ × 2 mol HNO₃/1 mol Zn(OH)₂ = 0.074 mol HNO₃

  • Step 4: Calculate the molarity of HNO₃.

[HNO₃] = 0.074 mol / 0.0150 L = 4.9 M

10.5 milliliters of 3.5 M zinc hydroxide react completely with 15.0 milliliters of 4.9 M nitric acid.

According to the bohr model, what determines the shortest wavelength in a given series of wavelengths emitted by the atom?
algol13

According to the bohr model "The lower energy level into which the electron deflects from a higher energy level is designated by the quantum number nf" determines the shortest wavelength in a given series of wavelengths emitted by the atom.

By explaining that electrons move in fixed orbitals (shells) and not anywhere in between, Bohr theory amended the atomic structure model.

He also showed that each orbit (shell) has a fixed energy. Bohr refined Rutherford's model of the atom's nucleus to include electrons and their varying energy levels.

According to Rydberg formula

1/λ = R [1/ni² - 1/nf²]

λ = wavelength

R = Rydberg constant

ni & nf are integers or principal quantum numbers where nf > ni

So if we want wavelength(λ) to be shortest, then 1/nf should be zero.

In this way , it depends on nf and not on ni

That's why the lower energy level into which the electron deflects from a higher energy level is designated by the quantum number nf" determines the shortest wavelength in a given series of wavelengths emitted by the atom.

AnnyKZ [126]

Answer: Read through this, hope It helps

Explanation:

Covalent bonds are formed when nonmetals form compounds with each other by sharing electrons between them.

Ionic bonds are formed when one ion — an atom or molecule with a net charge, either positive or negative — finds another ion of the opposite charge to bond with, creating an overall neutral ionic compound.

Where in the cell do transcription and translation take place? Transcription takes place in a protein, and translation takes pla
oksano4ka [1.4K]

Answer:

The correct answer will be option-Transcription takes place in the nucleus, and translation takes place in ribosomes.  

Explanation:

The regulation of gene is regulated and controlled by two main processes of central dogma called transcription and translation.

Transcription is the process of formation of messenger RNA or mRNA from a single strand of DNA whereas translation is the formation of protein from mRNA.

This process takes place in different sites in prokaryotes and eukaryotes. In prokaryotes, both transcription and translation take place in the cytoplasm but in eukaryotes, the transcription takes place in the nucleus whereas translation takes place in the ribosomes present in the cytoplasm.

Thus, the selected option is the correct answer.
