Answer:

Two of the three salts are soluble.

One of the three salts is soluble.

Explanation:

<em>One or two of the three salts would be soluble in water depending on if the water is cold or hot.</em>

<u>According to the solubility rules of chloride salts, all chlorides are soluble in cold water except for those of silver (Ag), lead (Pb), and mercury (I) (Hg). </u>

This thus means that both AgCl and PbCl_2 would be insoluble in cold water while LiCl would be soluble.

PbCl_2 is, however soluble in hot water.

Hence, in cold water, one of the three salts (LiCl) would be soluble, while in hot water, two of the three salts (LiCl and PbCl_2) would be soluble.

What mass of cucl2 is contained in 75.85 g of a 22.4% by mass solution of cucl2 in water?
Sindrei [870]
First  step: convert   22.4%  into   fraction
 that  is  22.4/100  which  is equivalent  to 0.224
  The  mass  of Cucl2  contained  in  75.85  of  22.4%  by  mass  of   solution  of  CUcl2 in  water is   therefore,
0.224 x75.85=16.99g
alternatively
75.85 --->100%
      ?        22.4%
by cross  multiplication =(22.4 x 75.85)/100 =16.99g

Of the following: H2(g); He(g); CO2(g); which would behave least like an ideal gas? Why?
Margarita [4]
Answer:

CO2(g)

Because CO2 is the larges molecule with specific geometric, therefore it is not likely to behave as an ideal gas.

10.0 mL of a HF solution was titrated with a 0.120 N solution of KOH; 29.6 mL of
Ilia_Sergeevich [38]

Answer:

0.355 N of HF

Explanation:

The titration reaction of HF with KOH is:

HF + KOH → H₂O + KF

<em>Where 1 mole of HF reacts per mole of KOH</em>

<em />

Moles of KOH are:

0.0296L × (0.120 equivalents / L) = 3.552x10⁻³ equivalents of KOH = equivalents of HF.

As volume of the titrated solution was 10.0mL, normality of HF solution is:

3.552x10⁻³ equivalents of HF / 0.010L =<em> 0.355 N of HF</em>
