Ill give brainliest for correct answer!!

For the reaction represented by the equation KClO3 > KCl + O2, how many moles of potassium chlorate (KClO3) are required to produce 250.0 g of oxygen?

I'm really confused :(

Iwould go with i'm not positive because i'm dumb that

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
