Question

2) Name the type of chemical reaction in the following equation.
3. CaO+H2o=Ca(OH) 2
b. 3 BaCl2 + Al(SO4)3= 3BaSO4 + AlCl3
c. 2FeSO4 = Fe203 + SO2+ SO3​

Answer 1

a) combination reaction

b)double displacement reaction

c) decomposition reaction

Answer 2

$\:$

Answer:

1) CaO+H2O----->Ca(OH)2

This is a Combination Reaction:

When two or more substances react to form a single product.

Other examples:

2Mg+O2----->2MgO

2) 3BaCl2+Al2(SO4)3------>3BaSO4+AlCl3

This is a double displacement reaction:

There is a mutual exchange of ions between the reactants.

Other examples:

CaCl2 + Na2CO3 → 2NaCl + CaCO3

3) 2FeSO4------>Fe2O3+SO2+SO3

This is a decomposition reaction.

Here, a single reactant breaks down to form simpler products.

Example:

CaCO3-------->CaO+CO2.
