When zinc oxide (ZnO) is mixed with vinegar, which contains acetic acid (CH₃COOH), a chemical reaction occurs. The acetic acid reacts with zinc oxide to form zinc acetate, water, and carbon dioxide gas, which may be observed as bubbles. This reaction highlights zinc oxide's amphoteric nature, as it can react with both acids and bases. The end result is a solution containing dissolved zinc acetate.
A solution of vinegar is obtained with a layer of oil on the top.
If you mix water and vinegar (acetic acid) it forms a homogeneous solution (mixture). Shaking it and letting it stand for 5 minutes will not change the appearance or the composition of the solution. So, basically noting happens.
Nothing will happen to the penny unless kept under vinegar for a very long time.Vinegar is acetic acid but, is a weak acid.Therefore,the property of acid to liberate hydrogen when an active metal is put in it or reacted with it will also be weak. A penny made of ,say copper is not a so very active metal.Therfore it will be time taking for it to react.If it does react ,then there will be a green/blue precipitate seen in the solution,due to formation of copper acetate.
When you mix cornstarch and vinegar together, it is a chemical change. This is because a new substance is formed due to the reaction between the cornstarch and vinegar.
When vinegar and soap are mixed together, the soap can be neutralized by the acidity of the vinegar, causing it to lose its effectiveness in cleaning. It is not recommended to mix vinegar and soap as this can render both components less effective for cleaning purposes.
u get zinc oxide
When iron is mixed with zinc oxide and heated, a redox reaction occurs where the iron reduces the zinc oxide to form zinc and iron oxide. The temperature needed for this reaction is significantly higher than normal atmospheric conditions.
Nothing

wel u put the mixture in a glass cup and pour vinegar and salt and surgar into it. mix it around by putting ur hand on top of the glass and shake.the apply 2 pints of water and shake it. then watch as they separate!!!!!!!!!! its cool. trust me=)
You get a physical change (the corn starch dissolves in the vinegar).
nothing
You will ruin the battery.
Not much will happen if you mix baking soda with water. If you mix it with vinegar something will happen. Vinegar is more acidic.
you get lovely salad dressing
bubbles
You get h i g h like a rocket!
