Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Now, as the stoichiometrical factors are in terms of mole but no information about neither the temperature nor the pressure is given, by means of the Avogadro's law, one could perform the stoichiometric calculations with the given volume as both the pressure and temperature remain the same, that is:
Such 1:1 volume relationship equals the 1:1 molar relationship given in the chemical reaction in terms of their stoichiometric coefficients, therefore, the yielded volume of carbon dioxide is also 9.23m³
Best regards.
Hey There!:
The density is the quotient between the mass of a material and the volume occupied by it, The density can be expressed for a substance or for a mixture of substances. For example, water density in ambient conditions is equal to 1.00 g/cm3, which means that in 1 cm³ or 1 mL, there are 1.0 g of water. Therefore:
D = m / V
D = 20 g / 5 mL
D = 4,0 g/mL
hope that helps!

Bohr's model explained the position of the electron, proton, and neutron in the atom of the element. The energy at the n = 2 level of the atom will be - 3.40 eV.
<h3>What is the principal quantum number (n)?</h3>
The principal quantum number (n) has been the distance of the electron of that atom in the nucleus and its energy in the structure. It can also be said to define the size of the atomic orbit.
n = 2 is the first excited state whose energy is calculated as:
Eₙ = − 13.6 ÷ n² eV
E₂ = - 13.6 eV ÷ 2²
= -3.40 eV
Therefore, -3.40 eV is the energy of electron at n = 2.

Answer:
Explanation:
Since the crystal structure is FCC , every unit cell will have 4 atoms . If a be the edge length
average density = 4 x average atomic no / volume of unit cell x N
N is avogadro no or 6.02 x 10²³
average atomic no
= 100 / (87/107.9 +13/106.4) = 107.72
average density = 100 / (87/10.49 + 13/12.02)
= 10.667
10.667 = (4 x 107.72 )/ (a³x 6.02 x 10²³)
a³ = 4 x 107.72 / (10.667 x 6.02 x 10²³)
= 6.71 x 10⁻²³
a = 4.063 x 10⁻⁸ m
