Ba(NO₃)₂(aq) + Na₂SO₄(aq) → BaSO₄(s) + 2NaNO₃(aq)
Ba²⁺ + SO₄²⁻ → BaSO₄
Answer:
Option A, C, D
Explanation:
A reversible adiabatic process is an isentropic process as entropy remains constant. Thus,
Entropy change (Delta S) = integral of (Q_rev)/T
Thus, option A and C are correct
For a reversible process, entropy generation is a positive quantity or zero. hence, statement B is not true
In an Adiabatic processes, entropy do not decrease. Hence, option D is also correct
Answer:
Molarity of acid soln = 0.176M
Explanation:
Molarity of NaOH soln x Volume of NaOH soln = Molarity of acid soln x Volume of acid soln
=> 26.23ml x 1.008M = 150.2ml x Molarity of acid solution
=> Molarity of acid soln = (26.23ml)(1.008M)/(150.2ml) = 0.176M
The layers of the atmosphere are defined by variations in temperature and pressure with altitude. These include the troposphere (0 to 16 km), stratosphere (16 to 50 km), mesosphere (50 to 80km) and thermosphere (80 to 640km).
Answer:
76.5g is present in 2.55mol of diazine
Explanation:
no. of mole equals mass over molar mass
molar mass of diazine equals 30g/mol.. then substitute to get the mass in grams which is 76.5g
