Explanation:Movable sodium chloride and silver nitrate 2 IN () solution
Answer:
4. 1HCL + 1NAOH- I NACL+1H2O
Explanation:
there is 2 hydrogens on the left side of the equation, balancing out to the other side of the equation. everything else would be balanced out too
Answer:

Explanation:
2AgNO₃(aq) + Na₂S(aq) => 2NaNO₃(aq) + Ag₂S(s)
given 2.0g 2.5g Spec Ions Driving Force ppt
= 2.0g/169.8g·mol⁻¹ =2.5g/78g·mol⁻¹
= 0.012mol =0.032mol
0.012/2=>0.006* 0.032/1=>0.032*
Limiting Reactant => *Dividing moles by respective coefficient => Limiting Reactant is the smaller resulting value. Therefore <u>AgNO₃ is the Limiting Reagent</u>
Theoretical Yield of ppt Ag₂S(s) = 1/2(0.012 mol) = 0.006 mol Ag₂S(s) = 0.006mol(246g·mol⁻¹ ) =<u> 1.48g Ag₂S(s)</u>
%Yield = (Lab Yield/Theoretical Yield) x 100% = (1.25g/1.48g)100% =<u> 84%</u>
Reagent in Excess => Na₂S(aq) => 0.032mol is given but only 0.016mol is consumed in the reaction. That is, (0.032 - 0.016)mol = 0.016mol Na₂S(aq) remains in excess = (0.016mol)(78g·mol⁻¹) = <u>1.25g Na₂S(aq) in excess.</u>
