Mass in grams of 4.25 × 10³ mol of N2?

Chemistry
1 answer:
Lesechka [4]2 years ago
7 0

Answer:

From the periodic table: mass of nitrogen = 14 grams. This means that: molar mass of N2 = 2*14 = 28 grams. Now, number of moles can be calculated using the following rule: number of moles = mass / molar mass. Therefore: mass = number of moles * molar mass. mass = 4.25*10^3 * 28.

Why can’t elements be separated into smaller parts using chemical means?
fenix001 [56]
Why can't elements be separated into smaller parts using chemical means? Too much energy is required, since you'd have to break them down into protons, neutrons, and electrons. You can get this much energy together with nuclear reactions, but not by chemical means.

Calcula el pH de las siguientes sustancias formadas durante una erupción volcánica:
Virty [35]

<em>Calculate the pH of the following substances formed during a volcanic eruption: </em>

<em>• Acid rain if the [H +] is 1.9 x 10-5 </em>

<em>• Sulfurous acid if [H +] = 0.10 </em>

<em>• Nitric acid if [H +] = 0.11</em>

<em />

<h3>Further explanation  </h3>

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.  

pH = - log [H⁺]  

  • pH acid rain

\tt pH=-log[1.9\times 10^{-5}]\\\\pH=5-log1.9\\\\pH=4.72

  • pH Sulfurous acid

\tt pH=-log[10^{-1}]\\\\pH=1

  • pH Nitric acid

\tt pH=-log[11\times 10^{-2}]\\\\pH=2-log~11=0.959

When a hydrogen atom makes the transition from the second excited state to the ground state (at -13.6 eV) the energy of the phot
viktelen [127]

Answer : The energy of the photon emitted is, -12.1 eV

Explanation :

First we have to calculate the 'n^{th}' orbit of hydrogen atom.

Formula used :

E_n=-13.6\times \frac{Z^2}{n^2}ev

where,

E_n = energy of n^{th} orbit

n = number of orbit

Z = atomic number  of hydrogen atom = 1

Energy of n = 1 in an hydrogen atom:

E_1=-13.6\times \frac{1^2}{1^2}eV=-13.6eV

Energy of n = 2 in an hydrogen atom:

E_3=-13.6\times \frac{1^2}{3^2}eV=-1.51eV

Energy change transition from n = 1 to n = 3 occurs.

Let energy change be E.

E=E_-E_3=(-13.6eV)-(-1.51eV)=-12.1eV

The negative sign indicates that energy of the photon emitted.

Thus, the energy of the photon emitted is, -12.1 eV
