What type of chemical reaction is Ba(ClO3)2 --> BaCl2 + O2.
1 answer:
→
is a decomposition reaction. Barium chlorate
decomposes to give barium chloride and oxygen.
A decomposition reaction can be defined as a chemical reaction in which one reactant breaks down into two or more products.
A decomposition reaction produces multiple products from a single reactant.
Combustion reactions are the combination of some compound with oxygen to make oxides of the other elements as products.
Hence, →
is a decomposition reaction. Barium chlorate
decomposes to give barium chloride and oxygen.

Answer:
Explanation:
First, we find in the tables the ΔH of formation of each compound. As you can see in the (image 1)
Then we solve the ecuation for ΔH°reaction
ΔH°reaction=∑ΔH°f(products)−∑ΔH°f(Reactants)
ΔH°reaction= (-2* 393.5 - 2*285.8) - (52.4 + 0) kJ/mol
ΔH°reaction = -1.41 *10^3 kJ/mol
