Answer:
1.5 moles
Explanation:
Given data:
Number of moles of O₂ consumed = 2.5 mol
Moles of CO₂ produced = ?
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Now we will compare the moles of oxygen with carbon dioxide from balance chemical equation:
O₂ : CO₂
5 : 3
2.5 : 3/5×2.5 = 1.5
Thus from 2.5 moles of oxygen 1.5 moles of carbon dioxide are produced.
Answer:
Combustibility is a measure of how easily a substance bursts into flame, through fire or combustion. This is an important property to consider when a substance is used for construction or is being stored. It is also important in processes that produce combustible substances as by product
Answer is: chromium (Cr).
Chromium with atomic number 24, it means it has 24 protons and 24 electrons.
Electron configuration of chromim atom: ₂₄Cr 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s¹.
In chromium, half full d-sub level (3d) is more stable than a partially filled d sub-level (3d⁴), thai is why an electron from the 4s orbital goes to a 3d orbital.
