Here we have to identify a piece of iron by its chemical property.
There are several chemical properties of iron for its identification but the simplest way to identify one of the renowned chemical property of iron is the formation of rust on iron in presence of water.
The iron in presence of water forms different types of iron oxides like hydrated Iron (III) oxide [Fe₂O₃.nH₂O], Iron (III) oxide-hydroxide [FeO(OH). Fe(OH)₃].
The rust is brown in color and forms only by keeping the iron piece in atmosphere. Although the humidity has an effect on the formation. The more humid the atmosphere there will be more chance to form rust on iron rod.
Answer:
2800 g de ácido nítrico
Explanation:
La ecuación por la oxidación de amoniaco es:
4NH₃ + 7O₂ → 4H₂O + 2HNO₂ + 2HNO₃
Si pensamos que el oxígeno es el reactivo limitante, trabajamos con el amoniaco. Convertimos su masa a moles:
1.36 kg = 1360 g
1360 g . 1mol /17g = 80 moles
Si 4 moles de amoniaco pueden producir 2 moles de acido nítrico
80 moles producirán, (80 . 2)/4 = 40 moles.
Convertimos los moles a gramos:
40 mol . 63g /mol = 2520 g
Si le aplicamos la pureza
2520 g . 100/90 = 2800 g
Sc (neutral) [Ar] 3d1 4s2
Sc+ [Ar] 3d1 4s1
Sc2+ [Ar] 3d1
hope this helped!
Answer: Vander waals
Explanation:
Tellurium is a chemical element with atomic number 52. It's symbol is Te.
Nitrogen is a chemical element with atomic number 14. Its symbol is N
VANDER WAALS bond is found between Nitrogen and Tellurium, just as in Tellurium(II) Nitrogen.
This bond is relatively weak compared to some other kinds of bonds.
That is why tellurium and most of its compounds are usually brittle and easily grounded.
So, Vander Waals bonds is the answer
Answer:
His phraseology and his turns of invention are too empirically pseudoscientific for the simplicity of nature.
