Heterogeneous. It doesn't make one single, consistent substance (it still has chunks in it) so it couldn't be homogeneous.
Heterogeneous. You can see the different parts: bread, peanut butter.
Depends in what context you mean "homogeneous". In an economics sense, you could classify "chunky peanut butter" as homogeneous if you wanted it to mean that all batches/brands of chunky peanut butter are essentially "interchangeable". (Whether that's a reasonable statement, I'm not sure. In the UK it is a reasonable assumption since peanut butter isn't really a "big thing" here, in the way that it seems to be in the US. I suspect the US market may feature slightly more brand loyalty than is experienced here...) If you mean homogeneous in texture, chunky peanut butter is not a homogeneous substance, due to the "chunks". However smooth peanut butter would (or at least, "should", by definition) be homogeneous.

The sandwich is Heterogenous, the bread and peanut butter are homogenous since you can't seperate them into the original ingredients.
The main difference between smooth and chunky peanut butter is one has actual peanuts mixed in with creamy peanut butter. Looking at both side by side, smooth peanut butter is creamy while the chunky has tiny lumps. They also may come in different colored labels.

No. Crunchy peanut butter is a heterogeneous mixture.
Peanut butter won
Heterogeneous mixture
because yo face is chunkey
Due to the way that it is made. Some peanut butter is made with the peanuts still in there, so that would make it "chunkier". But some peanut butter is smooth because they take out the peanuts and other such ingredients.
