Respuesta :
The balanced chemical reaction is [tex]CaCl_{2} + Na_{2}CO_{3}[/tex] → [tex]CaCO_{3} + 2NaCl[/tex].It is kind of double displacement reaction.
What is balanced chemical reaction?
An equation that has the same quantity of elements on both sides of the arrow has been shown to represent a balanced chemical reaction.
What is double displacement reaction.?
A class of reaction called a double displacement reaction involves the exchange of ions between two reactants to create two new molecules.
It is known that (50 ml) × (2 M [tex]CaCl_{2}[/tex]) = 100 m mol [tex]CaCl_{2}[/tex].
(50 mL ) × (3.M [tex]NaHCO_{3}[/tex] ) = 150 m Mol [tex]Na_{2}CO_{3}[/tex]
(c) It can be seen that [tex]CaCl_{2}[/tex] reacts with 100 mili moles of [tex]Na_{2}CO_{3}[/tex] but [tex]Na_{2}CO_{3}[/tex] have more amount hence, [tex]CaCl_{2}[/tex] will be limiting reagent.
(d) The amount of precipitate will be 10 g [tex]CaCO_{3}[/tex].
(100 mmol [tex]CaCl_{2}[/tex] ) × (1 mol [tex]CaCO_{3}[/tex] / 1 mol [tex]CaCl_{2}[/tex] ) × (100.875 g [tex]CaCO_{3}[/tex] /mol ) = 10 g [tex]CaCO_{3}[/tex].
(e) The percent yield will be (8.29 g / 10 g ) = 0.829 = 83 %.yield
