Explanation:
Please find the attached file for the solution:
The true statements are B, C, and D
-first ( A ) the concentrations of reactants and products are equal is false, As the concentrations of reactants and products may be different from each other.
- But (B) the concentrations of reactants and product remains constant is true, as the equilibrium remains when there is no change in the concentration of the reactants and products.
-(c) reactants are being converted to products (and vise verse) is true also, as there are reactions still happened at a constant rate so it looks like nothing is happening.
Answer:
0.44 m is the molality
Explanation:
Molality means mol of solute in 1kg of solvent.
Solute → CdBr₂
Solvent → H₂O
Mass / Molar mass = 45.38 g / 272.21 g/m = 0.167 moles
1 g = 1x10⁻³ kg
375 g = 0.375 kg
0.167 m/0.375 kg = 0.44 m
