Does the antifreeze you put in a car radiator have a lower or higher freezing point than water
saveliy_v [14]
Hello!
Antifreeze says it in the name. This means that it helps prevent freezing. The liquid that would freeze if you wouldnt use the antifreeze is water. This means that the antifreeze has to have a higher freezing point then water, because otherwise it would only freeze faster!

Hope this helped you!

A solution of NaCl ( aq ) is added slowly to a solution of lead nitrate, Pb ( NO 3 ) 2 ( aq ) , until no further precipitation o
statuscvo [17]

Answer : The molarity of Pb(NO_3)_2  solution is, 0.352 M

Explanation :

First we have to calculate the moles of PbCl_2

\text{Moles of }PbCl_2=\frac{\text{Given mass }PbCl_2}{\text{Molar mass }PbCl_2}

Molar mass of PbCl_2 = 278.1 g/mol

\text{Moles of }PbCl_2=\frac{19.58g}{278.1g/mol}=0.07041mol

Now we have to calculate the moles of CaCl_2

The balanced chemical equation is:

Pb(NO_3)_2(aq)+2NaCl(aq)\rightarrow PbCl_2(s)+2NaNO_3(aq)

From the balanced reaction we conclude that

As, 1 mole of PbCl_2 produced from 1 mole of Pb(NO_3)_2

So, 0.07041 mole of PbCl_2 produced from 0.07041 mole of Pb(NO_3)_2

Now we have to calculate the molarity of Pb(NO_3)_2

\text{Molarity of }Pb(NO_3)_2=\frac{\text{Moles of }Pb(NO_3)_2}{\text{Volume of solution in (L)}}

\text{Molarity of }Pb(NO_3)_2=\frac{0.07041mol}{0.200L}=0.352M

Therefore, the molarity of Pb(NO_3)_2  solution is, 0.352 M
