homogenous
yes.
It's a chemical change because the lemon and water cannot be separated by physical means. If it were a physical change, then the lemons and water would not be dissolved.
I think the answer you're looking for is a "Chemical Reaction". For instance, combining Hydrochloric Acid (HCl) and Sodium Hydroxide (NaOH) will cause a Chemical Reaction resulting in salt water (NaCl + H20).
No. A chemical reaction is not alive.
A chemical reaction is a reaction in which elements have their chemical and/or physical properties altered by the end of the reaction.
Juice is not a reaction; it is a liquid mixture.
there is no chemicle reaction
It depends what happened to the glass of juice...? An object is not a change =P
maybe
Yes, grape juice is slightly acidic
yes
physical reaction
When metal is brought into contact with fruit juice, the reaction is that of mild corrosion. This is because of the chemical makeup of both substances.
yes.
== == Washing Soda+lemon juice=co2+other products == == A chemical reaction has taken place between the reactants, washing soda and lemon juice. Carbon dioxide is one of the products. the chemical change cannot be reversed. So it is a irreversible change.
There is no Chemical Reaction involved in the freezing of apple juice. It is purely a Physical change. However, if the apple juice has fermented into hard cider (a Chemical Reaction) freezing it will cause the alcohol to separate as Apple Jack (a liquid) and the remainder of the cider will solidify ... again a Physical change.
