most cleaning products are (bases or acids)?
base
very reactive because they accept a hydrogen ion
exothermic
in this type of reaction heat is released in to the surroundings by forming bonds
products
substances that form in a reaction
molecular mass
atomic mass of a compound if you add up the mass of each element
acid
