Pb(NO3)2 + 2KCl ------) PbCl2 + 2KNO3
Pb+2 + 2Cl- ---------) PbCl2
<span>Mendeleev's solution was to group elements that shared similar properties, after the table was revised according to atomic number, newly discovered elements fell into place. </span>
Moles of NaCl
Molality
i is vant Hoff factor
For NaCl vant Hoff factor is 2( Actually 1.9)
Add up all the grams to get 9.96, then divide the amount if each element by the total;
4.56 of Pb divided by 9.96 = 0.4578313 now multiply by 100 and get 45.8% of Pb, then do the same for the rest of the elements, hope this helped <3
Answer:
Heterogenous
Explanation:
Heterozygous mixtures seperate and consist of two or more layers. For example, When oil and water are combined, they do not mix evenly, but instead form two separate layers. They also use filter and can scatter light.
