Answer:
Mass = 80.6 g
Explanation:
Given data:
Mass of N₂ consumed = ?
Mass of CaCN₂ formed = 265 g
Solution:
Chemical equation:
CaC₂ + N₂ → CaCN₂ + C
Number of moles of CaCN₂:
Number of moles = mass/molar mass
Number of moles = 265 g/ 92.11 g/mol
Number of moles = 2.88 mol
Now we will compare the moles of CaCN₂ and N₂.
CaCN₂ : N₂
1 : 1
2.88 : 2.88
Mass of N₂:
Mass = number of moles × molar mass
Mass = 2.88 mol × 28 g/mol
Mass = 80.6 g
The correct answer of the given question above would be a PICTOGRAM. OSHA’s required pictograms must be in the shape of a square set at a point and
include a black hazard symbol on a white background with a red frame sufficiently wide enough to
be clearly visible.
Answer:
The chemical equilibrium of the system will be unaffected. The chemical equilibrium of the system will shift to the right to favor the forward reaction. The chemical equilibrium of the system will shift to the left to favor the reverse reaction. (I hope this helped!!)
Answer:
See explanation below
Explanation:
When the bromine (Br₂) reacts in presence of FeBr₃ with the isopropylbenzene, the isopropylbenzene is a ring activator, therefore, it will promote the substitution in the ortho and para positions. However, as the Isopropyl is voluminic, the ortho position would have steric hindrance and hence, this product is not formed in greater proportions. Instead, the para position becomes more available to reaction, and this product is formed in majority.
The mechanism of reaction can be seen in the following picture, along with the products of the reaction
