Day2 Day 3 TEP Quizz

Types of chemical reaction EXCEPT:

• Combination

• Decomposition

• Displacement or substitution

• Composition

• Precipitation

What you understand regarding reversible reaction:

• the reactant and product 100% react

• Some reactant will always present in product

• the reactions are occurring simultaneously

• the reactions can be forward and backwork

Which is not Le Chatelier's principle:

• Change in concentration

• Change in Pressure

• Change in Level

• Change in Temperature

What is the function of catalyst?

• Slow down reaction

• Make product quality good

• boost the reaction forward

• Boost the reaction backward

Choose below that related to acid.

• Organic acid

• Inorganic acid

• H+

• COOH

• HO-

What are alkali ?

• OH-

• H2O

• H+

• COOH

Can acid reaction with alkali? if yes, normally what are the reactant produce?

• Yes, H2 and CO

• Yes, Salt and H2O

• No. acid react only with H2 gas

• No,
