If 3. 95 g of n2h4 reacts with excess oxygen and produces 0. 650 l of n2 , at 295 k and 1. 00 atm, what is the percent yield of the reaction?.

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

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
