Its because that is the sensation triggered by the part of your taste buds sensitive to the chemical structure of sugar.Humans are hard-wired for three main flavors: salt, fat and sugar.Thats because
The question asks, you want to electroplate a spoon with gold.
You want the gold to be 10 um thick on the spoon (40 cm^2).
I know how to solve this problem except for finding the volume for the equa
But of course we can use acids to make hydrogen fuel.
2HC(aq) + Zn(s) --> ZnCl2(aq) + H2(g)
How practical it is is another matter.It costs energy and therefore, money to make HCl and to refine the z
it all depends buddy
if u want spicy food or acidic itll be at least 5 or 6just anything between is fine but anything extreme like 2 or 12 is dangerous fyi soda is between 3 and 4
