Answer:
The answer to your question is 17.2 g of AgCl
Explanation:
Data
mass of NaCl = 7 g
mass of AgNO₃ = 95 g
mass of AgCl = ?
Balanced chemical reaction
NaCl + AgNO₃ ⇒ AgCl + NaNO₃
Process
1.- Calculate the molar mass of the reactants
NaCl = 23 + 35.5 = 58.5 g
AgNO₃ = 108 + 14 + 48 = 170 g
2.- Calculate the limiting reactant
theoretical yield = AgNO₃ / NaCl = 170 / 58.5 = 2.9
experimental yield = AgNO₃ / NaCl = 95 / 7 = 13.6 g
From these results we conclude that the limiting reactant is NaCl because the experimental yield was lower than the theoretical yield.
3.- Calculate the mass of AgCl
Molar mass of AgCl = 108 + 35.5 = 143.5 g
-Use proportions
58.5 g of NaCl ------------------ 143.5 g of AgCl
7.0 g of NaCl ------------------- x
x = (7 x 143.5) / 58.5
x = 17.2 g of AgCl

Answer:
The answer to your question is letter C.
Explanation:
Reaction
Potassium hydroxide = KOH
Barium chloride = BaCl₂
Potassium chloride = KCl
Barium hydroxide = Ba(OH)₂
KOH + BaCl₂ ⇒ KCl + Ba(OH)₂
Reactant Elements Products
1 K 1
1 Ba 1
2 Cl 1
1 H 2
1 O 2
The reaction is unbalanced
2KOH + BaCl₂ ⇒ 2KCl + Ba(OH)₂
Reactant Elements Products
2 K 2
1 Ba 1
2 Cl 2
2 H 2
2 O 2
Now, the reaction is balanced
