Match the type of reaction with its example equation.

displacement /ab = a + b

combination /a+bc=ab+c

decomposition /a+b=ab

➷ Displacement reactants are when one element replaces the other in a compound

Displacement : A + BC = AB + C

As you can see, in this reaction, 'A' has replaced 'C' in the compound 'BC'

Combination reactions are simply when two elements combine

Combination: A + B = AB

As you can see, 'A' and 'B' have combined to form 'AB'

Decomposition is when the compound is broken down

AB = A + B

As you can see 'AB' has broken down into just 'A' and 'B'

➶ Good Luck (:

➶ Have A Great Day ^-^

i think it's the first one because doctors aren't the ones who get rid of the old needles. most of them time it's not even doctors who give you shots, it's nurses.
