Answer is:  the maximum wavelength of light is 7.34 × 10⁻⁷ m.

E= 163 kJ/mol; bond energy of one mole of nitrogen.

E = 163000 J/mol ÷ 6.022·10²³ 1/mol.

E = 2.707·10⁻¹⁹ J; bond energy per molecule.

E = h·c/λ.

c = 3.00 × 10⁸ m/s; light speed.

h = 6.62607004·10⁻³⁴ J·s; Planck constant.

λ(photon) = h·c/E.

λ(photon) = 6.62607004·10⁻³⁴ J·s · 3.00 × 10⁸ m/s ÷ 2.707·10⁻¹⁹ J.

λ(photon) = 7.34 × 10⁻⁷ m.

λ(photon) = 734 nm.

Two scientists, Tara and Victor, work in the same scientific field of study. Victor asks Tara to review a research paper that he
sashaice [31]

Answer:

Tara does not get the same results when she conducts the experiment

Explanation:

<em>The most likely reason Tara suggested to Victor to perform the experiment again before publication would be because she did not get the same results when she conducted the experiment.</em>

A good scientific research or experiment should have an element of reproducibility. In order words, the claim made in published scientific research should be reproducible by any other scientist that decides to replicate the research. <u>Tara repeated Victor's experiment in order to check its reproducibility and when she could not reproduce the results, she had to tell Victor to conduct the experiment again before deciding to publish it.</u>

What is the molarity of a solution prepared by dissolving 30.0 grams of NaOH in enough water to make a solution with a total vol
Simora [160]

Answer:

\fbox{0.3125 M}

Given:

  • Given mass of NaOH = 30 gram
  • Molar mass of NaOH = 40 gram
  • Volume = 2.40 litres

To find:

Molarity = ?

Solution:

<em>Molarity is nothing but the number of moles of solute dissolved in per litre of solution. given by </em><em>formula,</em>

Molarity =  \frac{given  \: mass}{molar \: mass  \times Volume}

\sf Molarity \: =  \frac{30}{40 \times 2.4}  = 0.3125  \: M
