Barium chloride and potassium carbonate combine to form barium
carbonate and potassium chloride. The equation for this chemical
reaction is shown below.
BaCl2 + K2CO3-->
BaCO3 + KCl
The reaction is a double displacement reaction.The double displacement reaction is the one when cations and anions of two different molecules switch their places.
No equation is not balance, in order to balance the equation just put the 2 as the coefficient of KCl.
BaCl2 + K2CO3 BaCo3 + 2KCl ( This is the balanced equation)
In the given equation
1mol of BCl2 produces 2mol of KCl.
2mol of BCl2 will produce , the number of mole of KCl = ?
Number of mole of KCl produced = 4mol (Answer)
Now number of grams of KCl = ?
weight in gram of KCL = number of moles molecular weight
= 4mol74.5g/mol
= 298g
