yep,d is right

Answer 4

Lol "D"

Answer 5

Answer 6

In a decomposition reaction: A reactant is broken down, into smaller products.
In a double displacement reaction: Two new products are formed by the 'swapping' of ions of the reactants, like NaI + HCL -> NaCl + HI
In an ionic reaction, ions are reacted together to form a new products.
In a synthesis reaction: smaller reactants react to create a larger product.
Is it clearer now?
