NaCi and Mg(CO3)2
A reaction doesn't occur.
double replacement
For a double replacement reaction to take place, one of following must occur:One product is only slightly soluble and precipitates from solutionOne product is a gas that bubbles out of the mixtureOne product is a molecular compound
Double Replacement
One example is the reaction between silver nitrate and potassium chloride, which produces silver chloride and potassium nitrate. The term (aq) means in aqueous solution, and the term (s) means that the compound is a solid. AgNO3(aq) + KCl(aq) ---> AgCl(s) + KNO3(aq) In a double replacement reaction, one of the products will be a solid, a gas, or water.
Double replacement
a single replacement has one product and the double replacement has two products.
Na2CO3 + CaCl2 >> CaCO3 + 2 NaCl ( double replacement)
A reaction doesn't occur.
Two products are formed; one is a precipitate.
Balancing equation of FeCl2 and Na2CO3 yield 2NaCl and FeCO3
2 reactants and 2 products.
In a double replacement reaction a change of bonds between reactants occur.

2 reactants and 2 products
A white precipitate, lead (II) carbonate, and aqueous sodium nitrate will form. The chemical equation is Pb(NO3)2(aq) + Na2CO3(aq) --> 2NaNO3(aq) + PbCO3(s). This type of reaction is called a double replacement or double displacement.
