1. Put the vegetable mix on the gas stove.

2. Put the vegetable mix over the gas stove.

3. Put the vegetable mix on the gas range.

4. Put the vegetable mix over the gas range.

(Which ones are grammatical? Which preposition do I have to use?)

1 and 3 are grammatical. As for the difference between range and stove, http://answers.yahoo.com/question/index?qid=20080322160757AACWRwb

has a good explanation.

Americans would probably be more likely to say "the mixed vegetables" than "the vegetable mix".

Putting it "on" the stove would indicate placing it on the surface of the stove. Putting it "over" the stove would indicate holding it above the surface of the stove.

I hope this helps a little more. Thanks for asking.

Among the given sentences, all four are grammatically correct. However, the choice of preposition can slightly change the meaning or emphasis of the sentence. Here's a breakdown of each sentence:

1. "Put the vegetable mix on the gas stove."
This sentence means that you should place the vegetable mix directly on top of the gas stove, perhaps in a pot or pan.

2. "Put the vegetable mix over the gas stove."
This sentence suggests that you should position the vegetable mix in a way that it covers or spans across the gas stove. It could imply that the vegetable mix is placed on a surface above the stove, like a wire rack or a tray.

3. "Put the vegetable mix on the gas range."
Similar to the first sentence, this one indicates that the vegetable mix should be placed directly on the gas range, using a pot or pan.

4. "Put the vegetable mix over the gas range."
This sentence, like the second one, implies that the vegetable mix should be positioned above the gas range, potentially covering or spanning across it. It suggests that the mix is on a surface above the range, such as a wire rack or a tray.

The choice of preposition depends on whether you want the vegetable mix directly on the stove or range (using "on"), or if you want it positioned above or covering the stove or range (using "over").
