Chemistry

The pH scale ranges from 0-14. A pH of 0-7 is considered acidic. The lower the pH, the stronger the acid. So a pH of perhaps 0-2 would be a strong acid while a pH closer to 7 may be considered a weak acid.

double displacement reaction is when the positive ion of one compound replaces the other, to form two new compounds.

Single displacement reaction is when one element replaces another in a compound

its a chemical reaction

• milk
• steel
• air

Catalysts are substances that increase the rate of a chemical reaction -APEX

Catalysts

The _____________ of an acid and a base is determined by how completely they dissociate in water.

strength

when one element replaces another element in a compound during a chemical reaction.

Breaking a substance down into two or more simpler substances is called as decomposition reaction.

Ab+cd+=ad+cb

A precipitation reaction contains two aqueous reactants, one aqueous product, and one solid product. A precipitation reaction will produce an insoluble product.

Sodium hydroxide, also known as lye or NaOH, is a common base. NaOH is a strong base, and thus fully dissociates in aqueous solution.

Adding.

Combustion. Any reaction that has O2 as a reactant is combustion.

Aspirin

acid + base → salt + water

Single displacement reaction and a double displacement reaction are redox reactions.

Hydrochloric acid -APEX;)

Oxygen.

This reaction can be synthesis or combination reaction.

Reactants (apex)

Apex- react with litmus paper and turn it read, produce a painful/burning sensation on skin
