Explain the concept of mole ratio as used in reaction stoichiometry problems

Substance that is formed as the results of a chemical reaction. a.The concept of mole ratio in reaction stoichiometry problems are used as conversion factors frommoles of a reactant to another.The ratio is also used to show the balance equation of the reaction occurring. For example, converting moles to grams.

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

Butterfly wingspan is 7.7
