Want this question answered?
The vinegar dissolves the powder and its particles sink to the bottom of the mixture, leaving a cloudy look.
Nothing !!
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.
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.
u get zinc oxide
a redox reaction takes place ( one gains oxygen and the other looses oxygen) the zinc (oxide) is displaced and the iron becomes iron oxide and zinc oxide becomes zinc
If you mean how do you create it, you react zinc oxide and phosphoric acid
If you mix Zinc with Zinc Chloride a heterogeneous mixture with no tendency toward chemical reaction is formed.
Nothing
what happens when you mix vinegar and baking soda
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=)
Nothing
it blows up
You get a physical change (the corn starch dissolves in the vinegar).
Any reaction occur.
nothing
