This is the whole question i only need number 3 answered pls, will give brainlies 1. Aluminium oxide is the catalyst. What is a catalyst? A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

2. What type of reaction is it? Neutralisation

3. What 2 products are formed? Highlight the two correct answers. alkene acid gas bromine alkane

The answer is b metal denting

I’m not sure about this question

Answer isno products will be formedyou need the required activation energy/good geometry  to be able to get a reaction going. (without favorable  geometry, more energy would be needed.)this is because molecules in a reaction have electrons surrounding them. as molecules approach one another, they start to slow down because of the like charge repulsion (electrons have a negative charge—like charges repel). the appropriate amount of energy is needed to overcome that mutual repulsion. without that amount of energy, the speed of the molecules will be slowed down to such an extent  they do not even collide; they end up rebounding from each other.
