Question

Element A and Element B chemically combine in a synthesis reaction. They would then be

a
a mixture
b
a compound
c
an element
d
a solution

Answer 1

Mixtures and solutions are both physical combinations, not chemical ones. An element is pure and uncombined.
Since none of those can be the possible answer, we're left with "a compound", which makes sense, since that is the chemical combination of elements

Answer 2

ahhhhh, alright I was thinking compound but I needed clarification, thank you

Answer 3

No problem!
