A scientific law describes an observed occurrence or phenomena.
Answer:
0.15 L
Explanation:
Step 1. Calculate the <em>moles of KF.</em>
Molar mass = 58.10 g/mol
Moles of KF = 8.0 × 1/58.10
Moles of KF = 0.138 mol KF
===============
Step 2. Calculate the <em>volume of KF
</em>
c = n/V Multiply both sides by V
V = 0.138 × 1/0.89
V = 0.15 L
Answer:
AgCl
Explanation:
The reaction of KCl (In aqueous phase K⁺ + Cl⁻) with AgNO₃ ((In aqueous phase Ag⁺ + NO₃⁻) produce:
Ag⁺ + Cl⁻ ⇄ AgCl(s)
The reaction has a k of 5.56x10¹⁰
That means you will produce 5.56x10¹⁰ molecules of AgCl per molecule of Ag⁺ and Cl⁻ in solution.
As the AgCl is in solid state, this molecules is the precipitate.
I hope it helps!
Explanation:
Is the loss of electrons, gains of oxygen or loss of hydrogen
Answer:
None of the options are correct.
Explanation:
1) when the temperature of the solution is increased the solubility of the gas in the liquid decreases , hence option 1 is incorrect.
2)The heat released by the dissolution of an ionic compound in water is heat of hydration of the compound and is independent of the initial temperature of the solution.
3) The solubility of a liquid in water is not affected significantly by the pressure changes in the system as gases only have a significant cahne in solubility with change in pressure.
