How many moles of co2 are produced when 84.0 mol o2 completely react?

84.0 mol H2O. The reaction of 84.0 mol of O2 produces 84.0 mol of CO2.

(a)Write the partially balanced equation in terms of O.

We assume that all the CO2 comes from the O in O2.

O2 + … → CO2

(b)Use the molar ratio of CO2:O2 to calculate the moles of CO2.

Moles of CO2 = 84.0 mol O2 x (1 mol CO2/1 mol O2) = 84.0 mol CO2

explanation:

i think option no d is the correct answer

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
