Answer:
The correct approach will be the "Linguistic-relativity hypothesis".
Explanation:
- This theory can be defined as either the Hypothesis of Sapir-Whorf. This theory proposes whether our cognitive capabilities are influenced by languages as well as decide how we start behaving and communicate throughout society.
- Sapir Whorf explains these variations throughout the nature of human language throughout the manner a person understands the world.
Answer:
Mass = 279.23 g
Explanation:
Given data:
Number of moles of Fe₂O₃ = 3 mol
Number of moles of Al = 5 mol
Maximum amount of iron produced by reaction = ?
Solution:
Chemical equation:
Fe₂O₃ + 2Al → Al₂O₃ + 2Fe
Now we will compare the moles of iron with Al and iron oxide.
Fe₂O₃ : Fe
1 : 2
3 : 2×3 = 6 mol
Al : Fe
2 : 2
5 : 5 mol
The number of moles of iron produced by Al are less so Al is limiting reacting and it will limit the amount of iron so maximum number of iron produced are 5 moles.
Mass of iron:
Mass = number of moles × molar mass
Mass = 5 mol × 55.845 g/mol
Mass = 279.23 g
Both liquids and gasses are fluids is the answer
NH₄Cl → NH₄⁺ + Cl⁻
NH₄⁺ (the ammonium cation)
