a compound + a compound-----%26gt; 2 compounds
and I know that a synthesis reaction is:
a compound + a compound----%26gt; one compound
But if you don't know the products, how can you tell the difference? They both start with a compoud + a compoud
??????
Example:
H2SO4+Mg(OH)2----%26gt;
synthesis? or double replacement?How can you tell the difference between a double replacement reaction and a synthesis reaction?Double replacement. This is a simple acid-base reaction, which is always double replacement.
H2SO4 + Mg(OH)2 鈫?MgSO4 + 2H2O
Check if the ions allow complete synthesis. Mg has a charge of +2. It cannot hold both the SO4 and the two OH ions, because that would overpower its charge. It has to lose one type of ion, therefore it cannot be a synthesis reaction.How can you tell the difference between a double replacement reaction and a synthesis reaction?synthesis, you only get MgSO4 and water.
