Answer:
M
Explanation:
The concentration of the analyte in the 5-mL flask would be M
This is a problem of simple dilution that can be solved using the dilution equation;
C1V1 = C2V2,
where C1 = initial concentration, V1 = initial volume, C2 = final concentration, and V2 = final volume.
<em>In this case, the initial concentration (C1) is not known, the initial volume (V1) is 1.00 mL, the final concentration is 6.97 x 10-5 M, and the final volume is 10.00 mL.</em>
Now, let us make the initial concentration the subject of the formula from the equation above;
C1 = C2V2/V1. Solve for C1 by substituting the other parameters.
C1 = 6.97 x 10-5 x 10/1 = M
Answer:
E°= E°cathode- E° anode= 0.271-0.330= -0.59V
Explanation:
NB: the stoichiometry does not affect E°values,
And the more positive the E° values , the greater it's tendency to become spontaneous and hence irreversible, and the more negative the E° values the more likely to become less spontaneous and reversible, hence the above reaction is reversible
Answer:
kinetic energy
Explanation:
When solids are heated the particles gain energy and start to vibrate faster and faster.
Hi there!
Liquid and gas phase can both allow objects to pass through them, whereas solid phase does not.
Hope this helps!

Answer:
Unsaturated.
Explanation:
Hello,
In this case, since the solubility is useful to determine whether a solute will completely dissolve in a solvent or not, we must recall the solubility of potassium chloride at 50 °C that is 42.6 g per 100 g of water, it means that 42.6 g of KCl will completely dissolve in 100 g of water at such temperature. In such a way, since 14 g in the same mass of water is by far lower than the solubility at this temperature we can infer that the formed solution is unsaturated.
Best regards.
