How many grams of Sodium (Na) would be needed to react with the 17 grams of Oxygen if we wanted to produce 25 grams of Sodium superoxide (Na2O)? Make
sure your answer follows the Law of Conservation of Matter (Mass).

2Na + O —> Na2O

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

answer

Idon't know hope someone you
