Answer:
0
Explanation:
pure elements will always possess an oxidation number of 0, regardless of their charge.
Answer:
The average translational kinetic energy per atom for nitrogen atoms (not N₂) in a gas of nitrogen at atmospheric pressure at a temperature of 81 ∘C = 7.32 × 10⁻²¹ J
Explanation:
Average translational kinetic energy is given by
Eₐᵥ₉ = 3RT/2Nₐ
R = molar gas constant
T = absolute temperature in Kelvin
Nₐ = Avogadro's constant
The average translational kinetic energy is given more conveniently as
Eₐᵥ₉ = 3kT/2
k = Boltzmann's constant = (R/Nₐ) = 1.381 × 10⁻²³ J/K
T = 81 + 273.15 = 353.15 K
Eₐᵥ₉ = (3 × 1.381 × 10⁻²³ × 353.15)/2 = 7.32 × 10⁻²¹ J
Aristotle considered correct over Democritus based on their time period because Aristotle was more popular than Democritus and had a better reputation, and his philosophical points overcame Democritus'. Aristotle was a famous scientist and know for being the teacher of Alexander The Great.
Answer: Materials that do not allow electricity to pass easily through them are called insulators. Rubber, glass, plastic, and cloth are poor conductors of electricity. This is why electrical wires are covered in rubber, plastic, or cloth.
Explanation: I hoped that helped plzz mark me as brainliest!
When a solid (solute) comes in contact with the liquid (solvent), the solute goes about C) dissolution, in which the solid dissolves into the liquid.
