When many were taught chemistry in the 1970s this was called a double decomposition reaction. It is now called a salt metathesis reaction and also double displacement reaction. There are examples and more information at the related link.
The reaction between hydrogen and iodine to form hydrogen iodide is a synthesis reaction, also known as a combination reaction. In this type of reaction, two or more reactants combine to form a single product.
Single replacement
A characteristic of a synthesis reaction is that two or more reactants combine to form a single product. This type of reaction is used to create new compounds by building larger molecules from smaller ones.
The general form for a double-displacement reaction is AB + CD -> AD + CB, where two compounds swap anions or cations to form two new compounds.
An exothermic chemical reaction.
yes because ab plus bc is ac
2ab
Commutativity.
The existence of the additive inverse (of ab).
associative property
the midpoint of AB.
C minus B equals AB
Yes an No. You can have blood type AB in following situations: AO+BO AO+BB AA+BO AA+BB AB+BB AA+AB AB+AB So there's more possible ways to get type AB other than the combination of ABs.
ab=1a+1b a is equal to either 0 or two, and b is equal to a
Yes.
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
