Answer:
The actual yield of iron is 0.208 moles.
Explanation:
Given data:
Moles of Fe₂O₃ = 0.301 mol
Mass of iron = 11.6 g
Actual yield of iron in moles = ?
Solution:
Number of moles = mass / molar mass
Number of moles = 11.6 g/ 55.85 g/mol
Number of moles = 0.208 mol
It is the actual yield of iron in moles.
Theoretical yield can be calculated from given data.
One mole of Fe₂O₃ produce two mole two mole of iron.
0.301 moles will produce:
0.301× 2 = 0.602 mol
Theoretical yield in moles will be 0.602 moles.
So, for compound with composition <span>NH3O</span> the correct structure would be <span>H2N−OH</span><span>. The structure of second type is stable for compound </span><span>NOF3</span> and may be observed for amine oxides like (C2H5)3N→O<span> or pyridine-N-oxide.

Answer:
4.1 * 10^-22 J
The wave belongs to the infra red portion of the electromagnetic spectrum.
Explanation:
From the formula;
E = hc/λ
We know that;
h= plank's constant = 6.6 * 10^-34 Js
c= speed of light = 3 * 10^8 m/s
λ = wavelength of the wave = 4.80 x 10^5 nm or 4.80 x 10^-4 m
Hence;
E= 6.6 * 10^-34 * 3 * 10^8/ 4.80 x 10^-4
E= 4.1 * 10^-22 J
The wave belongs to the infra red portion of the electromagnetic spectrum.
The element that is the main constituent of paper, diamond, and clothes, among others is CARBON. It forms covalent bonds with itself and other elements. It is one of the most abundant and accessible elements on Earth. All organic compounds consist of at least one Carbon atom.
