Answer:
6 mins
Explanation:
The time taken for Ar to effuse can be obtained as follow:
Time for Br₂ (t₁) = 12 mins
Molar mass of Br₂ (M₁) = 2 × 80 = 160 g/mol
Molar mass of Ar (M₂) = 40 g/mol
Time for Ar (t₂) =?
t₂/t₁= √(M₂/M₁)
t₂ / 12 = √(40/160)
Cross multiply
t₂ = 12 × √(40/160)
t₂ = 12 × 0.5
t₂ = 6 mins
Therefore, it will take 6 mins for the same amount of Ar to effused out.
Answer:
(a) Concentrated sulphuric acid is called the king of chemicals as it is a very strong acid and is highly corrosive. ... (c) If water is added to sulphuric acid, then a large amount of heat is evolved. This changes water to steam, which can splash the acid. Hence, it is dangerous
