I would think it is a heterogeneous mixture since it can't be an element since there are more than one type of atom, it can't be a compound since the leaves are not bonded together, and it can not be a homogeneous mixture since the leaves don't all blended together (the pile is not uniform) and you can distinguish all the different parts of the mixture. It can be considered a heterogeneous mixture since the leaves are mixed together (along with other things like dirt) in a non-uniform way so that you can point out the parts of the mixture and it does not look like one thing.
I hope this helps. Let me know in the comments if anything is unclear.

Answer:
Enthalpy of a reaction = P - R
Synthesis: ΔH = 25 kJ - (-30 kJ) = 55 kJ
Single Replacement: ΔH = 30kJ - 65 kJ = -35 kJ
Double Replacement: ΔH = 60 kJ - 10 kJ = 50 kJ

Answer:
graph 2
Explanation:
Graham's law:
∴v1: gas diffusion rate 1
∴ v2: gas diffusion rate 2
∴ M1: gas molecular weight 1
∴ M2: gas molecular weight 2
Let Y = R = v1/v2 and X = M2/M1
⇒ Y = √X
the graph for the function Y = √X; is as shown in graph 2.
