Question

1. The chemical reaction when two or more chemicals

bond together forming a new substance
Synthesis
Decomposition
2. What type of chemical reaction is this?
→Al + O₂
Al₂O3
Decomposition
Combination/Synthesis
Combustion
Single Displacement

Answer 1

Step-by-step explanation:

1) if it forms one product it is synthesis.

2) combination/synthesis as it forms 1 product. Your equation is hard to read(where the arrow is) so this answer is if the equation is Al + O2 ---> Al2O3

if the equation is Al2O3 ---> Al + O2 then it is decomposition
