Question

Can someone please hep me with grade 11 chemistry?! Types of Chemical reactions



1. How come my answer sheet says that

Calcium chloride + ammonium nitrate forms a chemical reaction?? I thought there was calcium nitrate and ammonium chloride are both aqueous so there's no reaction?

Answer 1

2. How come barium sulfate and calcium chloride DONT react? i thought they form a percipitate so therefore they reacted?!?!

Answer 2

3. How do I know when something is a synthesis reaction of double displaement or what not.

IE apparently CaO + H2O would create a synthesis reaction?

Answer 3

For 2, BaSO4 is insoluble in water, even though you put it into water with CaCl2, it is still insoluble and is still BaSO4

Answer 4

For 3, to my knowledge... CaO + H2O -> Ca(OH)2, which is the lime water. But I don't really know how it comes

Answer 5

THanks :)
