Achef makes salad dressing by mixing oil, vinegar, and spices. which type of matter is the salad dressing? a. element b. compound c. homogeneous mixture d. heterogeneous mixture

              Heterogeneous mixture

Explanation:

                      The easiest way of defining Heterogeneous mixture is that it is mixture in which the composition of components is not uniform. Also, the substances present in this mixture are visible to naked eye. In fact, the size of solutes in heterogeneous mixture is greater as compared to that the sizes of solutes in homogeneous solutions. hence in salad dressing the oil, vinegar and spices are all visible and can easily be seen by naked eye.

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
