The mixture used in today’s experiment was prepared as a 1: 1: 1 mixture (by mass) of sand, salt, and salicylic acid. what does this underlined term mean? do your results for the mass of each recovered solid indicate a 1: 1: 1 composition of the mixture? (firstly to mathematically calculate your own ratio, divide the smallest mass into itself and then into each of the two larger masses)

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
