Abeaker contains an aqueous solution of sodium acetate (nac2h3o2) of unknown concentration. a few crystals of sodium acetate are added to the beaker. they sink to the bottom of the beaker and remain there unchanged even after further mixing. what can you conclude about the level of saturation of the solution?

b i think it’s a water wheel turning in a stream

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

a electronegativity decreases beacuse the size of nucleus is bigger.
