Iconic compounds are electrolytes because they dissociate into ions when dissolved in water. Many molecules compounds are noneelectrolytes
Answer:1kg. Explanation: ( b is the symbol for molality, and molality is the number of moles of solute per kilogram of solvent). b=nm. 0.5=0.5m. m=1kg.

Answer:
Explanation:
Hello there!
In this case, according to the given information, it will be possible for us to use the Dalton's law, in order to solve this problem. However, we first need to calculate the mole fraction of oxygen by firstly calculating the moles of each gas:
Next, we calculate such mole fraction as follows:
Then, given the following equation:
So we solve for the total pressure as follows:

Answer:
Eªcell > 0; n = 2
Explanation:
The reaction:
I2 (s) + Pb (s) → 2 I- (aq) + Pb2+ (aq)
Is product favored.
A reaction that is product favored has ΔG < 0 (Spontaneous)
K > 1 (Because concentration of products is >>>> concentration reactants).
Eªcell > 0 Because reaction is spontaneous.
And n = 2 electrons because Pb(s) is oxidizing to Pb2+ and I₂ is reducing to I⁻ (2 electrons). Statements that are true are:
<h3>Eªcell > 0; n = 2</h3>
