Consider a hypothetical compound composed of elements X, Y, and Z with the
empirical formula X2YZ3. Given that the atomic masses of X, Y, and Z are 41.2,
57.7, and 63.9, respectively.
A. Calculate the percentage composition by mass of the compound. If the
molecular formula of the compound is found by molar mass determination to be
actually X4Y226.
B. What is the percentage of each element present? Explain your results.

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry

ill try to . no promises tho.

explanation:

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.
