Identify each of the following household substances as a strong electrolyte, weak electrolyte, or non-electrolyte: salt solution

wolverine [178]

Answer:

Electrolytes are substances that can ionize in water. They could be acids, bases or salts as long as they give ions when they dissolve in water.

Explanation:

Strong electrolytes completely ionize when dissolved in water, leaving no neutral molecules. The strong electrolytes here are: salt water, baking soda (NaHCO3) solution.
Weak electrolytes do not completely dissociate in solution, and hence have a low ionic yield. Examples of this would be vinegar and bleach (which could be sodium hypochlorite or chlorine, which are weakly dissociated).
Non-electrolytes will remain as molecules and are not ionized in water at all. In this case, sugar solution is a non-electrolytes, even though sugar dissolves in water, but it remains as a whole molecule and not ions.

Which of the following is the largest volume? 4.0 x 101 m3 3.8 x 107 cm3 3.8 x 105 dm3 3.8 x 108 mm3

fiasKO [112]

Answer : Option A) 4.0 X 101 $m^{3}$

Explanation : As per the measurement chart the greatest metric system is measured in meters.

So the rest values are given in the form of metric values which are obviously less than that of meters. values of centimeters, decimeter and millimeters are less than that of meters.

If you assume this reaction is driven to completion because of the large excess of one ion, what is the concentration of [Fe(SCN

viktelen [127]

Answer : The concentration of $[Fe(SCN)]^{2+}$ is, $4.32\times 10^{-4}M$

Explanation :

When we assume this reaction is driven to completion because of the large excess of one ion then we are assuming limiting reagent is $SCN^-$ and $Fe^{3+}$ is excess reagent.
