I’m a bit confused, anyone ?

Looking up graphs on google, you can see thaty = force(n)x = time(s)

In the question "in a solution of brine  (salt water), what is the  salt? " the correct answer is a solute. a solute is a component of a  solution  dissolved in the solvent.

Most elements have more than one naturally occurring isotope. as you learned previously, the atoms of those isotopes have the same atomic number (number of protons), making them belong to the same element, but they have different mass numbers (total number of protons and neutrons) giving them different atomic masses. so which mass is put on the periodic table for each element? is it the most common isotope’s mass? the heaviest mass? this activity will answer that question.
