Please help will mark brainliest 1) what proccess can be used to extract pure water from salt water ?
2) how is an element different to a compound

1= simple distillation

2 - elements contain just one type of atom ; compounds contain atoms of at least two different elements , which have been chemically combined or bonded

Explanation:

hope this helps

chromotragraphy

because it has mixture of compounds and elements

i think these are the answers

Explanation:

answer

the ions in solute supperate from eachouthere

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 !
