Answer:BaCl (aq)+ K2CO3 (aq)——> Ba2CO3 (aq) + KCl (aq)
Explanation:
The equation is already balanced and it is a double replacement reaction.

Boyle’s Boyle’s law I believe is correct answer
Answer: 11 g
Explanation:
Zn + 2HCl → ZnCl₂ + H₂
Number of moles of Zn:
Number of moles = 5 g / 65.38 g/mol
Number of moles = 0.08 mol
Number of moles of HCl :
Number of moles = 50 g / 36.5 g/mol
Number of moles = 1.4 mol
Compare the moles of both reactant with zinc chloride:
Zn : ZnCl₂
1 : 1
0.08 : 0.08
HCl : ZnCl₂
2 : 1
1.4 : 1/2×1.4 =0.7 mol
The number of moles of zinc chloride produced by Zn are less so it will limit reactants.
Mass of zinc chloride:
Mass = 0.08 mol × 136.3 g/mol
<u>Mass = 11 g</u>
