Answer 1

Answer:

DANG :/ IM TOO LATE

Explanation:

Answer 2

Answer:

Explanation: Unbalanced Equation;

Na³SO⁴+PbCl²=NaCl+ Pb³(SO⁴)²

Balanced Equation:

2(Na³SO⁴) +3PbCl²=6NaCl+Pb³(SO⁴)²

Mole ratio:2:3=6:1

Molar mass of Na³SO⁴=3×(23)+32+(4×16)

= 69+32+64

= 69+96=165g/mol

No. of moles in 84.05g of Na³SO⁴

=84.05/165

= 0.51 moles

Using the mole ratio, The number of NaCl moles=0.51×6/2

= 0.51×3

. = 1.53 moles

Mass of NaCl produced. = 1.53×23

= 35.19g
